Base class for scene graph nodes. A scene graph is a set of tree data structures where every item has zero or one parent, and each item is either a "leaf" with zero sub-items or a "branch" with zero or more sub-items.

Each item in the scene graph is called a Node. Branch nodes are of type Parent, whose concrete subclasses are Group, Region, and Control, or subclasses thereof.

Leaf nodes are classes such as Rectangle, Text, ImageView, MediaView, or other such leaf classes which cannot have children. Only a single node within each scene graph tree will have no parent, which is referred to as the "root" node.

There may be several trees in the scene graph. Some trees may be part of a Scene, in which case they are eligible to be displayed. Other trees might not be part of any Scene.

A node may occur at most once anywhere in the scene graph. Specifically, a node must appear no more than once in all of the following: as the root node of a Scene, the children ObservableList of a Parent, or as the clip of a Node.

The scene graph must not have cycles. A cycle would exist if a node is an ancestor of itself in the tree, considering the Group content ObservableList, Parent children ObservableList, and Node clip relationships mentioned above.

If a program adds a child node to a Parent (including Group, Region, etc) and that node is already a child of a different Parent or the root of a Scene, the node is automatically (and silently) removed from its former parent. If a program attempts to modify the scene graph in any other way that violates the above rules, an exception is thrown, the modification attempt is ignored and the scene graph is restored to its previous state.

It is possible to rearrange the structure of the scene graph, for example, to move a subtree from one location in the scene graph to another. In order to do this, one would normally remove the subtree from its old location before inserting it at the new location. However, the subtree will be automatically removed as described above if the application doesn't explicitly remove it.

Node objects may be constructed and modified on any thread as long they are not yet attached to a Scene in a Window that is showing. An application must attach nodes to such a Scene or modify them on the JavaFX Application Thread.

The JavaFX Application Thread is created as part of the startup process for the JavaFX runtime. See the Application class and the Platform.startup(Runnable) method for more information.

An application should not extend the Node class directly. Doing so may lead to an UnsupportedOperationException being thrown.

String ID

Each node in the scene graph can be given a unique id. This id is much like the "id" attribute of an HTML tag in that it is up to the designer and developer to ensure that the id is unique within the scene graph. A convenience function called lookup(String) can be used to find a node with a unique id within the scene graph, or within a subtree of the scene graph. The id can also be used identify nodes for applying styles; see the CSS section below.

Coordinate System

The Node class defines a traditional computer graphics "local" coordinate system in which the x axis increases to the right and the y axis increases downwards. The concrete node classes for shapes provide variables for defining the geometry and location of the shape within this local coordinate space. For example, Rectangle provides x, y, width, height variables while Circle provides centerX, centerY, and radius.

At the device pixel level, integer coordinates map onto the corners and cracks between the pixels and the centers of the pixels appear at the midpoints between integer pixel locations. Because all coordinate values are specified with floating point numbers, coordinates can precisely point to these corners (when the floating point values have exact integer values) or to any location on the pixel. For example, a coordinate of (0.5, 0.5) would point to the center of the upper left pixel on the Stage. Similarly, a rectangle at (0, 0) with dimensions of 10 by 10 would span from the upper left corner of the upper left pixel on the Stage to the lower right corner of the 10th pixel on the 10th scanline. The pixel center of the last pixel inside that rectangle would be at the coordinates (9.5, 9.5).

In practice, most nodes have transformations applied to their coordinate system as mentioned below. As a result, the information above describing the alignment of device coordinates to the pixel grid is relative to the transformed coordinates, not the local coordinates of the nodes. The Shape class describes some additional important context-specific information about coordinate mapping and how it can affect rendering.

Transformations

Any Node can have transformations applied to it. These include translation, rotation, scaling, or shearing.

A translation transformation is one which shifts the origin of the node's coordinate space along either the x or y axis. For example, if you create a Rectangle which is drawn at the origin (x=0, y=0) and has a width of 100 and a height of 50, and then apply a Translate with a shift of 10 along the x axis (x=10), then the rectangle will appear drawn at (x=10, y=0) and remain 100 points wide and 50 tall. Note that the origin was shifted, not the x variable of the rectangle.

A common node transform is a translation by an integer distance, most often used to lay out nodes on the stage. Such integer translations maintain the device pixel mapping so that local coordinates that are integers still map to the cracks between pixels.

A rotation transformation is one which rotates the coordinate space of the node about a specified "pivot" point, causing the node to appear rotated. For example, if you create a Rectangle which is drawn at the origin (x=0, y=0) and has a width of 100 and height of 30 and you apply a Rotate with a 90 degree rotation (angle=90) and a pivot at the origin (pivotX=0, pivotY=0), then the rectangle will be drawn as if its x and y were zero but its height was 100 and its width -30. That is, it is as if a pin is being stuck at the top left corner and the rectangle is rotating 90 degrees clockwise around that pin. If the pivot point is instead placed in the center of the rectangle (at point x=50, y=15) then the rectangle will instead appear to rotate about its center.

Note that as with all transformations, the x, y, width, and height variables of the rectangle (which remain relative to the local coordinate space) have not changed, but rather the transformation alters the entire coordinate space of the rectangle.

A scaling transformation causes a node to either appear larger or smaller depending on the scaling factor. Scaling alters the coordinate space of the node such that each unit of distance along the axis in local coordinates is multiplied by the scale factor. As with rotation transformations, scaling transformations are applied about a "pivot" point. You can think of this as the point in the Node around which you "zoom". For example, if you create a Rectangle with a strokeWidth of 5, and a width and height of 50, and you apply a Scale with scale factors (x=2.0, y=2.0) and a pivot at the origin (pivotX=0, pivotY=0), the entire rectangle (including the stroke) will double in size, growing to the right and downwards from the origin.

A shearing transformation, sometimes called a skew, effectively rotates one axis so that the x and y axes are no longer perpendicular.

Multiple transformations may be applied to a node. Custom transforms are applied using the transforms list. Predefined transforms are applied using the properties specified below. The matrices that represent the transforms are multiplied in this order:

  1. Layout (layoutX, layoutY) and translate (translateX, translateY, translateZ)
  2. Rotate (rotate)
  3. Scale (scaleX, scaleY, scaleZ)
  4. Transforms list (transforms) starting from element 0
The transforms are applied in the reverse order of the matrix multiplication outlined above: last element of the transforms list to 0th element, scale, rotate, and layout and translate. By applying the transforms in this order, the bounds in the local coordinates of the node are transformed to the bounds in the parent coordinate of the node (see the Bounding Rectangles section).

Bounding Rectangles

Since every Node has transformations, every Node's geometric bounding rectangle can be described differently depending on whether transformations are accounted for or not.

Each Node has a read-only boundsInLocal variable which specifies the bounding rectangle of the Node in untransformed local coordinates. boundsInLocal includes the Node's shape geometry, including any space required for a non-zero stroke that may fall outside the local position/size variables, and its clip and effect variables.

Each Node also has a read-only boundsInParent variable which specifies the bounding rectangle of the Node after all transformations have been applied as specified in the Transformations section. It is called "boundsInParent" because the rectangle will be relative to the parent's coordinate system. This is the 'visual' bounds of the node.

Finally, the layoutBounds variable defines the rectangular bounds of the Node that should be used as the basis for layout calculations and may differ from the visual bounds of the node. For shapes, Text, and ImageView, layoutBounds by default includes only the shape geometry, including space required for a non-zero strokeWidth, but does not include the effect, clip, or any transforms. For resizable classes (Regions and Controls) layoutBounds will always map to 0,0 width x height.

The image shows a node without any transformation and its boundsInLocal:

A sine wave shape enclosed by an axis-aligned rectangular bounds

If we rotate the image by 20 degrees we get following result:

An axis-aligned rectangular bounds that encloses the shape rotated by 20 degrees

The red rectangle represents boundsInParent in the coordinate space of the Node's parent. The boundsInLocal stays the same as in the first image, the green rectangle in this image represents boundsInLocal in the coordinate space of the Node.

The images show a filled and stroked rectangle and their bounds. The first rectangle [x:10.0 y:10.0 width:100.0 height:100.0 strokeWidth:0] has the following bounds bounds: [x:10.0 y:10.0 width:100.0 height:100.0]. The second rectangle [x:10.0 y:10.0 width:100.0 height:100.0 strokeWidth:5] has the following bounds: [x:7.5 y:7.5 width:105 height:105] (the stroke is centered by default, so only half of it is outside of the original bounds; it is also possible to create inside or outside stroke). Since neither of the rectangles has any transformation applied, boundsInParent and boundsInLocal are the same.

The rectangles are enclosed by their respective bounds

CSS

The Node class contains id, styleClass, and style variables that are used in styling this node from CSS. The id and styleClass variables are used in CSS style sheets to identify nodes to which styles should be applied. The style variable contains style properties and values that are applied directly to this node.

For further information about CSS and how to apply CSS styles to nodes, see the CSS Reference Guide.

JavaFX 2.0

  • Property Details

    • parent

      public final ReadOnlyObjectProperty<Parent> parentProperty
      The parent of this Node. If this Node has not been added to a scene graph, then parent will be null.
      Default value:
      null
      See Also:
      getParent()

    • scene

      public final ReadOnlyObjectProperty<Scene> sceneProperty
      The Scene that this Node is part of. If the Node is not part of a scene, then this variable will be null.
      Default value:
      null
      See Also:
      getScene()

    • id

      public final StringProperty idProperty
      The id of this Node. This simple string identifier is useful for finding a specific Node within the scene graph. While the id of a Node should be unique within the scene graph, this uniqueness is not enforced. This is analogous to the "id" attribute on an HTML element (CSS ID Specification).

      For example, if a Node is given the id of "myId", then the lookup method can be used to find this node as follows: scene.lookup("#myId");.

      Default value:
      null
      See Also:
      getId(), setId(String)

    • style

      public final StringProperty styleProperty
      A string representation of the CSS style associated with this specific Node. This is analogous to the "style" attribute of an HTML element. Note that, like the HTML style attribute, this variable contains style properties and values and not the selector portion of a style rule.
      Default value:
      empty string
      See Also:
      getStyle(), setStyle(String)

    • visible

      public final BooleanProperty visibleProperty
      Specifies whether this Node and any subnodes should be rendered as part of the scene graph. A node may be visible and yet not be shown in the rendered scene if, for instance, it is off the screen or obscured by another Node. Invisible nodes never receive mouse events or keyboard focus and never maintain keyboard focus when they become invisible.
      Default value:
      true
      See Also:
      isVisible(), setVisible(boolean)

    • cursor

      public final ObjectProperty<Cursor> cursorProperty
      Defines the mouse cursor for this Node and subnodes. If null, then the cursor of the first parent node with a non-null cursor will be used. If no Node in the scene graph defines a cursor, then the cursor of the Scene will be used.
      Default value:
      null
      See Also:
      getCursor(), setCursor(Cursor)

    • opacity

      public final DoubleProperty opacityProperty
      Specifies how opaque (that is, solid) the Node appears. A Node with 0% opacity is fully translucent. That is, while it is still visible and rendered, you generally won't be able to see it. The exception to this rule is when the Node is combined with a blending mode and blend effect in which case a translucent Node may still have an impact in rendering. An opacity of 50% will render the node as being 50% transparent.

      A visible node with any opacity setting still receives mouse events and can receive keyboard focus. For example, if you want to have a large invisible rectangle overlay all Nodes in the scene graph in order to intercept mouse events but not be visible to the user, you could create a large Rectangle that had an opacity of 0%.

      Opacity is specified as a value between 0 and 1. Values less than 0 are treated as 0, values greater than 1 are treated as 1.

      On some platforms ImageView might not support opacity variable.

      There is a known limitation of mixing opacity < 1.0 with a 3D Transform. Opacity/Blending is essentially a 2D image operation. The result of an opacity < 1.0 set on a Group node with 3D transformed children will cause its children to be rendered in order without Z-buffering applied between those children.

      Default value:
      1.0
      See Also:
      getOpacity(), setOpacity(double)

    • blendMode

      public final ObjectProperty<BlendMode> blendModeProperty
      The BlendMode used to blend this individual node into the scene behind it. If this node is a Group, then all of the children will be composited individually into a temporary buffer using their own blend modes and then that temporary buffer will be composited into the scene using the specified blend mode. A value of null is treated as pass-through. This means no effect on a parent (such as a Group), and the equivalent of SRC_OVER for a single Node.
      Default value:
      null
      See Also:
      getBlendMode(), setBlendMode(BlendMode)

    • clip

      public final ObjectProperty<Node> clipProperty
      Specifies a Node to use to define the clipping shape for this Node. This clipping Node is not a child of this Node in the scene graph sense. Rather, it is used to define the clip for this Node.

      For example, you can use an ImageView Node as a mask to represent the Clip. Or you could use one of the geometric shape Nodes such as Rectangle or Circle. Or you could use a Text node to represent the Clip.

      See the class documentation for Node for scene graph structure restrictions on setting the clip. If these restrictions are violated by a change to the clip variable, the change is ignored and the previous value of the clip variable is restored.

      Note that this is a conditional feature. See ConditionalFeature.SHAPE_CLIP for more information.

      There is a known limitation of mixing Clip with a 3D Transform. Clipping is essentially a 2D image operation. The result of a Clip set on a Group node with 3D transformed children will cause its children to be rendered in order without Z-buffering applied between those children.

      Default value:
      null
      See Also:
      getClip(), setClip(Node)

    • cache

      public final BooleanProperty cacheProperty
      A performance hint to the system to indicate that this Node should be cached as a bitmap. Rendering a bitmap representation of a node will be faster than rendering primitives in many cases, especially in the case of primitives with effects applied (such as a blur). However, it also increases memory usage. This hint indicates whether that trade-off (increased memory usage for increased performance) is worthwhile. Also note that on some platforms such as GPU accelerated platforms there is little benefit to caching Nodes as bitmaps when blurs and other effects are used since they are very fast to render on the GPU. The cacheHintProperty() variable provides additional options for enabling more aggressive bitmap caching.

      Caching may be disabled for any node that has a 3D transform on itself, any of its ancestors, or any of its descendants.

      Default value:
      false
      See Also:
      isCache(), setCache(boolean)

    • cacheHint

      public final ObjectProperty<CacheHint> cacheHintProperty
      Additional hint for controlling bitmap caching.

      Under certain circumstances, such as animating nodes that are very expensive to render, it is desirable to be able to perform transformations on the node without having to regenerate the cached bitmap. An option in such cases is to perform the transforms on the cached bitmap itself.

      This technique can provide a dramatic improvement to animation performance, though may also result in a reduction in visual quality. The cacheHint variable provides a hint to the system about how and when that trade-off (visual quality for animation performance) is acceptable.

      It is possible to enable the cacheHint only at times when your node is animating. In this way, expensive nodes can appear on screen with full visual quality, yet still animate smoothly.

      Example: 

      
        expensiveNode.setCache(true);
        expensiveNode.setCacheHint(CacheHint.QUALITY);
        ...
        // Do an animation
        expensiveNode.setCacheHint(CacheHint.SPEED);
        new Timeline(
            new KeyFrame(Duration.seconds(2),
                new KeyValue(expensiveNode.scaleXProperty(), 2.0),
                new KeyValue(expensiveNode.scaleYProperty(), 2.0),
                new KeyValue(expensiveNode.rotateProperty(), 360),
                new KeyValue(expensiveNode.cacheHintProperty(), CacheHint.QUALITY)
            )
        ).play();
      Note that cacheHint is only a hint to the system. Depending on the details of the node or the transform, this hint may be ignored.

      If Node.cache is false, cacheHint is ignored. Caching may be disabled for any node that has a 3D transform on itself, any of its ancestors, or any of its descendants.

      Default value:
      CacheHint.DEFAULT
      See Also:
      getCacheHint(), setCacheHint(CacheHint)

    • effect

      public final ObjectProperty<Effect> effectProperty
      Specifies an effect to apply to this Node.

      Note that this is a conditional feature. See ConditionalFeature.EFFECT for more information.

      There is a known limitation of mixing Effect with a 3D Transform. Effect is essentially a 2D image operation. The result of an Effect set on a Group node with 3D transformed children will cause its children to be rendered in order without Z-buffering applied between those children.

      Default value:
      null
      See Also:
      getEffect(), setEffect(Effect)

    • depthTest

      public final ObjectProperty<DepthTest> depthTestProperty
      Indicates whether depth testing is used when rendering this node. If the depthTest flag is DepthTest.DISABLE, then depth testing is disabled for this node. If the depthTest flag is DepthTest.ENABLE, then depth testing is enabled for this node. If the depthTest flag is DepthTest.INHERIT, then depth testing is enabled for this node if it is enabled for the parent node or the parent node is null.

      The depthTest flag is only used when the depthBuffer flag for the Scene is true (meaning that the Scene has an associated depth buffer)

      Depth test comparison is only done among nodes with depthTest enabled. A node with depthTest disabled does not read, test, or write the depth buffer, that is to say its Z value will not be considered for depth testing with other nodes.

      Note that this is a conditional feature. See ConditionalFeature.SCENE3D for more information.

      See the constructor in Scene with depthBuffer as one of its input arguments.

      Default value:
      INHERIT
      See Also:
      getDepthTest(), setDepthTest(DepthTest)

    • disable

      public final BooleanProperty disableProperty
      Defines the individual disabled state of this Node. Setting disable to true will cause this Node and any subnodes to become disabled. This property should be used only to set the disabled state of a Node. For querying the disabled state of a Node, the disabled property should instead be used, since it is possible that a Node was disabled as a result of an ancestor being disabled even if the individual disable state on this Node is false.
      Default value:
      false
      See Also:
      isDisable(), setDisable(boolean)

    • pickOnBounds

      public final BooleanProperty pickOnBoundsProperty
      Defines how the picking computation is done for this node when triggered by a MouseEvent or a contains function call. If pickOnBounds is true, then picking is computed by intersecting with the bounds of this node, else picking is computed by intersecting with the geometric shape of this node. The default value of this property is false unless overridden by a subclass. The default value is true for Region.
      Default value:
      false; true for Region
      See Also:
      isPickOnBounds(), setPickOnBounds(boolean)

    • disabled

      public final ReadOnlyBooleanProperty disabledProperty
      Indicates whether or not this Node is disabled. A Node will become disabled if disable is set to true on either itself or one of its ancestors in the scene graph.

      A disabled Node should render itself differently to indicate its disabled state to the user. Such disabled rendering is dependent on the implementation of the Node. The shape classes contained in javafx.scene.shape do not implement such rendering by default, therefore applications using shapes for handling input must implement appropriate disabled rendering themselves. The user-interface controls defined in javafx.scene.control will implement disabled-sensitive rendering, however.

      A disabled Node does not receive mouse or key events.

      Default value:
      false
      See Also:
      isDisabled(), setDisabled(boolean)

    • onDragEntered

      public final ObjectProperty<EventHandler<? super DragEvent>> onDragEnteredProperty
      Defines a function to be called when drag gesture enters this Node.
      See Also:
      getOnDragEntered(), setOnDragEntered(EventHandler)

    • onDragExited

      public final ObjectProperty<EventHandler<? super DragEvent>> onDragExitedProperty
      Defines a function to be called when drag gesture exits this Node.
      See Also:
      getOnDragExited(), setOnDragExited(EventHandler)

    • onDragOver

      public final ObjectProperty<EventHandler<? super DragEvent>> onDragOverProperty
      Defines a function to be called when drag gesture progresses within this Node.
      See Also:
      getOnDragOver(), setOnDragOver(EventHandler)

    • onDragDropped

      public final ObjectProperty<EventHandler<? super DragEvent>> onDragDroppedProperty
      Defines a function to be called when the mouse button is released on this Node during drag and drop gesture. Transfer of data from the DragEvent's dragboard should happen in this function.
      See Also:
      getOnDragDropped(), setOnDragDropped(EventHandler)

    • onDragDone

      public final ObjectProperty<EventHandler<? super DragEvent>> onDragDoneProperty
      Defines a function to be called when this Node is a drag and drop gesture source after its data has been dropped on a drop target. The transferMode of the event shows what just happened at the drop target. If transferMode has the value MOVE, then the source can clear out its data. Clearing the source's data gives the appropriate appearance to a user that the data has been moved by the drag and drop gesture. A transferMode that has the value NONE indicates that no data was transferred during the drag and drop gesture.
      See Also:
      getOnDragDone(), setOnDragDone(EventHandler)

    • managed

      public final BooleanProperty managedProperty
      Defines whether or not this node's layout will be managed by it's parent. If the node is managed, it's parent will factor the node's geometry into its own preferred size and layoutBounds calculations and will lay it out during the scene's layout pass. If a managed node's layoutBounds changes, it will automatically trigger relayout up the scene-graph to the nearest layout root (which is typically the scene's root node).

      If the node is unmanaged, its parent will ignore the child in both preferred size computations and layout. Changes in layoutBounds will not trigger relayout above it. If an unmanaged node is of type Parent, it will act as a "layout root", meaning that calls to Parent.requestLayout() beneath it will cause only the branch rooted by the node to be relayed out, thereby isolating layout changes to that root and below. It's the application's responsibility to set the size and position of an unmanaged node.

      By default all nodes are managed.

      See Also:
      isManaged(), setManaged(boolean)

    • layoutX

      public final DoubleProperty layoutXProperty
      Defines the x coordinate of the translation that is added to this Node's transform for the purpose of layout. The value should be computed as the offset required to adjust the position of the node from its current layoutBounds minX position (which might not be 0) to the desired location.

      For example, if textnode should be positioned at finalX 

      
     textnode.setLayoutX(finalX - textnode.getLayoutBounds().getMinX());

      Failure to subtract layoutBounds minX may result in misplacement of the node. The relocate(x, y) method will automatically do the correct computation and should generally be used over setting layoutX directly.

      The node's final translation will be computed as layoutX + translateX, where layoutX establishes the node's stable position and translateX optionally makes dynamic adjustments to that position.

      If the node is managed and has a Region as its parent, then the layout region will set layoutX according to its own layout policy. If the node is unmanaged or parented by a Group, then the application may set layoutX directly to position it.

      See Also:
      getLayoutX(), setLayoutX(double)

    • layoutY

      public final DoubleProperty layoutYProperty
      Defines the y coordinate of the translation that is added to this Node's transform for the purpose of layout. The value should be computed as the offset required to adjust the position of the node from its current layoutBounds minY position (which might not be 0) to the desired location.

      For example, if textnode should be positioned at finalY 

      
     textnode.setLayoutY(finalY - textnode.getLayoutBounds().getMinY());

      Failure to subtract layoutBounds minY may result in misplacement of the node. The relocate(x, y) method will automatically do the correct computation and should generally be used over setting layoutY directly.

      The node's final translation will be computed as layoutY + translateY, where layoutY establishes the node's stable position and translateY optionally makes dynamic adjustments to that position.

      If the node is managed and has a Region as its parent, then the region will set layoutY according to its own layout policy. If the node is unmanaged or parented by a Group, then the application may set layoutY directly to position it.

      See Also:
      getLayoutY(), setLayoutY(double)

    • boundsInParent

      public final ReadOnlyObjectProperty<Bounds> boundsInParentProperty
      The rectangular bounds of this Node in the parent coordinate system. boundsInParent is calculated by taking the local bounds and applying the node transforms as specified in the Transformations section of the class doc.

      The resulting bounds will be conceptually in the coordinate space of the Node's parent, however, the node need not have a parent to calculate these bounds.

      Note that this method does not take the node's visibility into account; the computation is based on the geometry of this Node only.

      This property will always have a non-null value.

      Note that boundsInParent is automatically recomputed whenever the geometry of a node changes, or when any of the following the change: transforms ObservableList, any of the translate, layout or scale variables, or the rotate variable. For this reason, it is an error to bind any of these values in a node to an expression that depends upon this variable. For example, the x or y variables of a shape, or translateX, translateY should never be bound to boundsInParent for the purpose of positioning the node.

      See also the Bounding Rectangles section.

      See Also:
      getBoundsInParent()

    • boundsInLocal

      public final ReadOnlyObjectProperty<Bounds> boundsInLocalProperty
      The rectangular bounds of this Node in the node's untransformed local coordinate space. For nodes that extend Shape, the local bounds will also include space required for a non-zero stroke that may fall outside the shape's geometry that is defined by position and size attributes. The local bounds will also include any clipping set with clip as well as effects set with effect.

      Note that this method does not take the node's visibility into account; the computation is based on the geometry of this Node only.

      This property will always have a non-null value.

      Note that boundsInLocal is automatically recomputed whenever the geometry of a node changes. For this reason, it is an error to bind any of these values in a node to an expression that depends upon this variable. For example, the x or y variables of a shape should never be bound to boundsInLocal for the purpose of positioning the node.

      See Also:
      getBoundsInLocal()

    • layoutBounds

      public final ReadOnlyObjectProperty<Bounds> layoutBoundsProperty
      The rectangular bounds that should be used for layout calculations for this node. layoutBounds may differ from the visual bounds of the node and is computed differently depending on the node type.

      If the node type is resizable (Region, Control, or WebView) then the layoutBounds will always be 0,0 width x height. If the node type is not resizable (Shape, Text, or Group), then the layoutBounds are computed based on the node's geometric properties and does not include the node's clip, effect, or transforms. See individual class documentation for details.

      Note that the layoutX, layoutY, translateX, and translateY variables are not included in the layoutBounds. This is important because layout code must first determine the current size and location of the node (using layoutBounds) and then set layoutX and layoutY to adjust the translation of the node so that it will have the desired layout position.

      Because the computation of layoutBounds is often tied to a node's geometric variables, it is an error to bind any such variables to an expression that depends upon layoutBounds. For example, the x or y variables of a shape should never be bound to layoutBounds for the purpose of positioning the node.

      Note that for 3D shapes, the layout bounds is actually a rectangular box with X, Y, and Z values, although only X and Y are used in layout calculations.

      The layoutBounds will never be null.

      getLayoutBounds()

    • viewOrder

      public final DoubleProperty viewOrderProperty
      Defines the rendering and picking order of this Node within its parent.

      This property is used to alter the rendering and picking order of a node within its parent without reordering the parent's children list. For example, this can be used as a more efficient way to implement transparency sorting. To do this, an application can assign the viewOrder value of each node to the computed distance between that node and the viewer.

      The parent will traverse its children in decreasing viewOrder order. This means that a child with a lower viewOrder will be in front of a child with a higher viewOrder. If two children have the same viewOrder, the parent will traverse them in the order they appear in the parent's children list.

      However, viewOrder does not alter the layout and focus traversal order of this Node within its parent. A parent always traverses its children list in order when doing layout or focus traversal.

      Default value:
      0.0
      Since:
      9
      See Also:
      getViewOrder(), setViewOrder(double)

    • translateX

      public final DoubleProperty translateXProperty
      Defines the x coordinate of the translation that is added to this Node's transform.

      The node's final translation will be computed as layoutX + translateX, where layoutX establishes the node's stable position and translateX optionally makes dynamic adjustments to that position.

      This variable can be used to alter the location of a node without disturbing its layoutBounds, which makes it useful for animating a node's location.

      Default value:
      0
      See Also:
      getTranslateX(), setTranslateX(double)

    • translateY

      public final DoubleProperty translateYProperty
      Defines the y coordinate of the translation that is added to this Node's transform.

      The node's final translation will be computed as layoutY + translateY, where layoutY establishes the node's stable position and translateY optionally makes dynamic adjustments to that position.

      This variable can be used to alter the location of a node without disturbing its layoutBounds, which makes it useful for animating a node's location.

      Default value:
      0
      See Also:
      getTranslateY(), setTranslateY(double)

    • translateZ

      public final DoubleProperty translateZProperty
      Defines the Z coordinate of the translation that is added to the transformed coordinates of this Node. This value will be added to any translation defined by the transforms ObservableList and layoutZ.

      This variable can be used to alter the location of a Node without disturbing its layout bounds, which makes it useful for animating a node's location.

      Note that this is a conditional feature. See ConditionalFeature.SCENE3D for more information.

      Default value:
      0
      See Also:
      getTranslateZ(), setTranslateZ(double)

    • scaleX

      public final DoubleProperty scaleXProperty
      Defines the factor by which coordinates are scaled about the center of the object along the X axis of this Node. This is used to stretch or shrink the node either manually or by using an animation.

      This scale factor is not included in layoutBounds by default, which makes it ideal for scaling the entire node after all effects and transforms have been taken into account.

      The pivot point about which the scale occurs is the center of the untransformed layoutBounds.

      Default value:
      1.0
      See Also:
      getScaleX(), setScaleX(double)

    • scaleY

      public final DoubleProperty scaleYProperty
      Defines the factor by which coordinates are scaled about the center of the object along the Y axis of this Node. This is used to stretch or shrink the node either manually or by using an animation.

      This scale factor is not included in layoutBounds by default, which makes it ideal for scaling the entire node after all effects and transforms have been taken into account.

      The pivot point about which the scale occurs is the center of the untransformed layoutBounds.

      Default value:
      1.0
      See Also:
      getScaleY(), setScaleY(double)

    • scaleZ

      public final DoubleProperty scaleZProperty
      Defines the factor by which coordinates are scaled about the center of the object along the Z axis of this Node. This is used to stretch or shrink the node either manually or by using an animation.

      This scale factor is not included in layoutBounds by default, which makes it ideal for scaling the entire node after all effects and transforms have been taken into account.

      The pivot point about which the scale occurs is the center of the rectangular bounds formed by taking boundsInLocal and applying all the transforms in the transforms ObservableList.

      Note that this is a conditional feature. See ConditionalFeature.SCENE3D for more information.

      Default value:
      1.0
      See Also:
      getScaleZ(), setScaleZ(double)

    • rotate

      public final DoubleProperty rotateProperty
      Defines the angle of rotation about the Node's center, measured in degrees. This is used to rotate the Node.

      This rotation factor is not included in layoutBounds by default, which makes it ideal for rotating the entire node after all effects and transforms have been taken into account.

      The pivot point about which the rotation occurs is the center of the untransformed layoutBounds.

      Note that because the pivot point is computed as the center of this Node's layout bounds, any change to the layout bounds will cause the pivot point to change, which can move the object. For a leaf node, any change to the geometry will cause the layout bounds to change. For a group node, any change to any of its children, including a change in a child's geometry, clip, effect, position, orientation, or scale, will cause the group's layout bounds to change. If this movement of the pivot point is not desired, applications should instead use the Node's transforms ObservableList, and add a Rotate transform, which has a user-specifiable pivot point.

      Default value:
      0.0
      See Also:
      getRotate(), setRotate(double)

    • rotationAxis

      public final ObjectProperty<Point3D> rotationAxisProperty

      Note that this is a conditional feature. See ConditionalFeature.SCENE3D for more information.

      Default value:
      Rotate.Z_AXIS
      See Also:
      getRotationAxis(), setRotationAxis(Point3D)

    • localToParentTransform

      See Also:
      getLocalToParentTransform()

    • localToSceneTransform

      public final ReadOnlyObjectProperty<Transform> localToSceneTransformProperty
      An affine transform that holds the computed local-to-scene transform. This is the concatenation of all transforms in this node's parents and in this node, including all of the convenience transforms up to the root. If this node is in a SubScene, this property represents transforms up to the subscene, not the root scene.

      Note that when you register a listener or a binding to this property, it needs to listen for invalidation on all its parents to the root node. This means that registering a listener on this property on many nodes may negatively affect performance of transformation changes in their common parents.

      Since:
      JavaFX 2.2
      See Also:
      getLocalToSceneTransform()

    • nodeOrientation

      public final ObjectProperty<NodeOrientation> nodeOrientationProperty
      Property holding NodeOrientation.

      Node orientation describes the flow of visual data within a node. In the English speaking world, visual data normally flows from left-to-right. In an Arabic or Hebrew world, visual data flows from right-to-left. This is consistent with the reading order of text in both worlds. The default value is left-to-right.

      Since:
      JavaFX 8.0

      isMouseTransparent(), setMouseTransparent(boolean)

    • hover

      public final ReadOnlyBooleanProperty hoverProperty
      Whether or not this Node is being hovered over. Typically this is due to the mouse being over the node, though it could be due to a pen hovering on a graphics tablet or other form of input.

      Note that current implementation of hover relies on mouse enter and exit events to determine whether this Node is in the hover state; this means that this feature is currently supported only on systems that have a mouse. Future implementations may provide alternative means of supporting hover.

      Default value:
      false
      See Also:
      isHover(), setHover(boolean)

    • getProperties

      public final ObservableMap<Object,​Object> getProperties()
      Returns an observable map of properties on this node for use primarily by application developers.
      API Note:
      Layout managers use this map as well to specify layout constraints on the node, such as HBox#setHgrow, so the developer should be mindful of clearing the map or overriding its values. These entries are not removed automatically if the node is removed from the layout manager, so unused entries can exist throughout the life of the node.
      Returns:
      an observable map of properties on this node for use primarily by application developers

    • hasProperties

      public boolean hasProperties()
      Tests if Node has properties.

      true if node has properties.

    • setUserData

      public void setUserData​(Object value)
      Convenience method for setting a single Object property that can be retrieved at a later date. This is functionally equivalent to calling the getProperties().put(Object key, Object value) method. This can later be retrieved by calling getUserData().
      Parameters:
      value - The value to be stored - this can later be retrieved by calling getUserData().

    • getUserData

      public Object getUserData()

    • setId

      public final void setId​(String value)
      Sets the value of the property id.
      Property description:
      The id of this Node. This simple string identifier is useful for finding a specific Node within the scene graph. While the id of a Node should be unique within the scene graph, this uniqueness is not enforced. This is analogous to the "id" attribute on an HTML element (CSS ID Specification).

      For example, if a Node is given the id of "myId", then the lookup method can be used to find this node as follows: scene.lookup("#myId");.

      Default value:
      null

    • getId

      Sets the value of the property visible.
      Property description:
      Specifies whether this Node and any subnodes should be rendered as part of the scene graph. A node may be visible and yet not be shown in the rendered scene if, for instance, it is off the screen or obscured by another Node.

      public final void setCursor​(Cursor value)
      Sets the value of the property cursor.
      Property description:
      Defines the mouse cursor for this Node and subnodes. If null, then the cursor of the first parent node with a non-null cursor will be used. If no Node in the scene graph defines a cursor, then the cursor of the Scene will be used.
      Default value:
      null

    • getCursor

      public final Cursor getCursor()
      Gets the value of the property cursor.
      Property description:
      Defines the mouse cursor for this Node and subnodes. If null, then the cursor of the first parent node with a non-null cursor will be used. If no Node in the scene graph defines a cursor, then the cursor of the Scene will be used.

    • setOpacity

      public final void setOpacity​(double value)
      Sets the value of the property opacity.
      Property description:
      Specifies how opaque (that is, solid) the Node appears. A Node with 0% opacity is fully translucent. That is, while it is still visible and rendered, you generally won't be able to see it. The exception to this rule is when the Node is combined with a blending mode and blend effect in which case a translucent Node may still have an impact in rendering. An opacity of 50% will render the node as being 50% transparent.

      A visible node with any opacity setting still receives mouse events and can receive keyboard focus. For example, if you want to have a large invisible rectangle overlay all Nodes in the scene graph in order to intercept mouse events but not be visible to the user, you could create a large Rectangle that had an opacity of 0%.

      Opacity is specified as a value between 0 and 1. Values less than 0 are treated as 0, values greater than 1 are treated as 1.

      On some platforms ImageView might not support opacity variable.

      There is a known limitation of mixing opacity < 1.0 with a 3D Transform. Opacity/Blending is essentially a 2D image operation. The result of an opacity < 1.0 set on a Group node with 3D transformed children will cause its children to be rendered in order without Z-buffering applied between those children.

      Default value:
      1.0

    • getOpacity

      public final double getOpacity()

    • setBlendMode

      public final void setBlendMode​(BlendMode value)
      Sets the value of the property blendMode.
      Property description:
      The BlendMode used to blend this individual node into the scene behind it. If this node is a Group, then all of the children will be composited individually into a temporary buffer using their own blend modes and then that temporary buffer will be composited into the scene using the specified blend mode. A value of null is treated as pass-through. This means no effect on a parent (such as a Group), and the equivalent of SRC_OVER for a single Node.
      Default value:
      null

    • setClip

      public final void setClip​(Node value)
      Sets the value of the property clip.
      Property description:
      Specifies a Node to use to define the clipping shape for this Node. This clipping Node is not a child of this Node in the scene graph sense. Rather, it is used to define the clip for this Node.

      For example, you can use an ImageView Node as a mask to represent the Clip. Or you could use one of the geometric shape Nodes such as Rectangle or Circle. Or you could use a Text node to represent the Clip.

      See the class documentation for Node for scene graph structure restrictions on setting the clip. If these restrictions are violated by a change to the clip variable, the change is ignored and the previous value of the clip variable is restored.

      Note that this is a conditional feature. See ConditionalFeature.SHAPE_CLIP for more information.

      There is a known limitation of mixing Clip with a 3D Transform. Clipping is essentially a 2D image operation. The result of a Clip set on a Group node with 3D transformed children will cause its children to be rendered in order without Z-buffering applied between those children.

    • setCache

      public final void setCache​(boolean value)
      Sets the value of the property cache.
      Property description:
      A performance hint to the system to indicate that this Node should be cached as a bitmap. Rendering a bitmap representation of a node will be faster than rendering primitives in many cases, especially in the case of primitives with effects applied (such as a blur). However, it also increases memory usage. This hint indicates whether that trade-off (increased memory usage for increased performance) is worthwhile. Also note that on some platforms such as GPU accelerated platforms there is little benefit to caching Nodes as bitmaps when blurs and other effects are used since they are very fast to render on the GPU. The cacheHintProperty() variable provides additional options for enabling more aggressive bitmap caching.

      Caching may be disabled for any node that has a 3D transform on itself, any of its ancestors, or any of its descendants.

      Default value:
      false

      public final void setCacheHint​(CacheHint value)
      Sets the value of the property cacheHint.
      Property description:
      Additional hint for controlling bitmap caching.

      Under certain circumstances, such as animating nodes that are very expensive to render, it is desirable to be able to perform transformations on the node without having to regenerate the cached bitmap. An option in such cases is to perform the transforms on the cached bitmap itself.

      This technique can provide a dramatic improvement to animation performance, though may also result in a reduction in visual quality. The cacheHint variable provides a hint to the system about how and when that trade-off (visual quality for animation performance) is acceptable.

      It is possible to enable the cacheHint only at times when your node is animating. In this way, expensive nodes can appear on screen with full visual quality, yet still animate smoothly.

      Example: 

      
        expensiveNode.setCache(true);
        expensiveNode.setCacheHint(CacheHint.QUALITY);
        ...
        // Do an animation

    • setDepthTest

      public final void setDepthTest​(DepthTest value)
      Sets the value of the property depthTest.
      Property description:
      Indicates whether depth testing is used when rendering this node. If the depthTest flag is DepthTest.DISABLE, then depth testing is disabled for this node. If the depthTest flag is DepthTest.ENABLE, then depth testing is enabled for this node. If the depthTest flag is DepthTest.INHERIT, then depth testing is enabled for this node if it is enabled for the parent node or the parent node is null.

      The depthTest flag is only used when the depthBuffer flag for the Scene is true (meaning that the Scene has an associated depth buffer)

      Depth test comparison is only done among nodes with depthTest enabled. A node with depthTest disabled does not read, test, or write the depth buffer, that is to say its Z value will not be considered for depth testing with other nodes.

      Note that this is a conditional feature. See ConditionalFeature.SCENE3D for more information.

      Sets the value of the property pickOnBounds.
      Property description:
      Defines how the picking computation is done for this node when triggered by a MouseEvent or a contains function call. If pickOnBounds is true, then picking is computed by intersecting with the bounds of this node, else picking is computed by intersecting with the geometric shape of this node.

    • setDisabled

      protected final void setDisabled​(boolean value)
      Sets the value of the property disabled.
      Property description:
      Indicates whether or not this Node is disabled. A Node will become disabled if disable is set to true on either itself or one of its ancestors in the scene graph.

      A disabled Node should render itself differently to indicate its disabled state to the user. Such disabled rendering is dependent on the implementation of the Node. The shape classes contained in javafx.scene.shape do not implement such rendering by default, therefore applications using shapes for handling input must implement appropriate disabled rendering themselves. The user-interface controls defined in javafx.scene.control will implement disabled-sensitive rendering, however.

      A disabled Node does not receive mouse or key events.

      Default value:
      false

    • lookup

      public Node lookup​(String selector)
      Finds this Node, or the first sub-node, based on the given CSS selector. If this node is a Parent, then this function will traverse down into the branch until it finds a match. If more than one sub-node matches the specified selector, this function returns the first of them.

      For example, if a Node is given the id of "myId", then the lookup method can be used to find this node as follows: scene.lookup("#myId");.

      Parameters:
      selector - The css selector of the node to find
      Returns:
      The first node, starting from this Node, which matches the CSS selector, null if none is found.

    • lookupAll

      public Set<Node> lookupAll​(String selector)
      Finds all Nodes, including this one and any children, which match the given CSS selector. If no matches are found, an empty unmodifiable set is returned. The set is explicitly unordered.
      Parameters:
      selector - The css selector of the nodes to find
      Returns:
      All nodes, starting from and including this Node, which match the CSS selector. The returned set is always unordered and unmodifiable, and never null.

    • toBack

      public void toBack()
      Moves this Node to the back of its sibling nodes in terms of z-order. This is accomplished by moving this Node to the first position in its parent's content ObservableList. This function has no effect if this Node is not part of a group.

    • toFront

      public void toFront()
      Moves this Node to the front of its sibling nodes in terms of z-order. This is accomplished by moving this Node to the last position in its parent's content ObservableList. This function has no effect if this Node is not part of a group.

    • snapshot

      public WritableImage snapshot​(SnapshotParameters params, WritableImage image)
      Takes a snapshot of this node and returns the rendered image when it is ready. CSS and layout processing will be done for the node, and any of its children, prior to rendering it. The entire destination image is cleared to the fill Paint specified by the SnapshotParameters. This node is then rendered to the image. If the viewport specified by the SnapshotParameters is null, the upper-left pixel of the boundsInParent of this node, after first applying the transform specified by the SnapshotParameters, is mapped to the upper-left pixel (0,0) in the image. If a non-null viewport is specified, the upper-left pixel of the viewport is mapped to upper-left pixel (0,0) in the image. In both cases, this mapping to (0,0) of the image is done with an integer translation. The portion of the node that is outside of the rendered image will be clipped by the image.

      When taking a snapshot of a scene that is being animated, either explicitly by the application or implicitly (such as chart animation), the snapshot will be rendered based on the state of the scene graph at the moment the snapshot is taken and will not reflect any subsequent animation changes.

      NOTE: In order for CSS and layout to function correctly, the node must be part of a Scene (the Scene may be attached to a Stage, but need not be).

      Parameters:
      params - the snapshot parameters containing attributes that will control the rendering. If the SnapshotParameters object is null, then the Scene's attributes will be used if this node is part of a scene, or default attributes will be used if this node is not part of a scene.
      image - the writable image that will be used to hold the rendered node. It may be null in which case a new WritableImage will be constructed. The new image is constructed using integer width and height values that are derived either from the transformed bounds of this Node or from the size of the viewport as specified in the SnapShotParameters. These integer values are chosen such that the image will wholly contain the bounds of this Node or the specified viewport. If the image is non-null, the node will be rendered into the existing image. In this case, the width and height of the image determine the area that is rendered instead of the width and height of the bounds or viewport.
      Returns:
      the rendered image
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      Since:
      JavaFX 2.2

    • snapshot

      public void snapshot​(Callback<SnapshotResult,​Void> callback, SnapshotParameters params, WritableImage image)
      Takes a snapshot of this node at the next frame and calls the specified callback method when the image is ready. CSS and layout processing will be done for the node, and any of its children, prior to rendering it. The entire destination image is cleared to the fill Paint specified by the SnapshotParameters. This node is then rendered to the image. If the viewport specified by the SnapshotParameters is null, the upper-left pixel of the boundsInParent of this node, after first applying the transform specified by the SnapshotParameters, is mapped to the upper-left pixel (0,0) in the image. If a non-null viewport is specified, the upper-left pixel of the viewport is mapped to upper-left pixel (0,0) in the image. In both cases, this mapping to (0,0) of the image is done with an integer translation. The portion of the node that is outside of the rendered image will be clipped by the image.

      This is an asynchronous call, which means that other events or animation might be processed before the node is rendered. If any such events modify the node, or any of its children, that modification will be reflected in the rendered image (just like it will also be reflected in the frame rendered to the Stage, if this node is part of a live scene graph).

      When taking a snapshot of a node that is being animated, either explicitly by the application or implicitly (such as chart animation), the snapshot will be rendered based on the state of the scene graph at the moment the snapshot is taken and will not reflect any subsequent animation changes.

      NOTE: In order for CSS and layout to function correctly, the node must be part of a Scene (the Scene may be attached to a Stage, but need not be).

      Parameters:
      callback - a class whose call method will be called when the image is ready. The SnapshotResult that is passed into the call method of the callback will contain the rendered image, the source node that was rendered, and a copy of the SnapshotParameters. The callback parameter must not be null.
      params - the snapshot parameters containing attributes that will control the rendering. If the SnapshotParameters object is null, then the Scene's attributes will be used if this node is part of a scene, or default attributes will be used if this node is not part of a scene.
      image - the writable image that will be used to hold the rendered node. It may be null in which case a new WritableImage will be constructed. The new image is constructed using integer width and height values that are derived either from the transformed bounds of this Node or from the size of the viewport as specified in the SnapShotParameters. These integer values are chosen such that the image will wholly contain the bounds of this Node or the specified viewport. If the image is non-null, the node will be rendered into the existing image. In this case, the width and height of the image determine the area that is rendered instead of the width and height of the bounds or viewport.
      Throws:
      IllegalStateException - if this method is called on a thread other than the JavaFX Application Thread.
      NullPointerException - if the callback parameter is null.

      JavaFX 2.2

    • startDragAndDrop

      public Dragboard startDragAndDrop​(TransferMode... transferModes)
      Confirms a potential drag and drop gesture that is recognized over this Node. Can be called only from a DRAG_DETECTED event handler. The returned Dragboard is used to transfer data during the drag and drop gesture. Placing this Node's data on the Dragboard also identifies this Node as the source of the drag and drop gesture. More detail about drag and drop gestures is described in the overivew of DragEvent.

    • setManaged

      public final void setManaged​(boolean value)
      Sets the value of the property managed.
      Property description:
      Defines whether or not this node's layout will be managed by it's parent. If the node is managed, it's parent will factor the node's geometry into its own preferred size and layoutBounds calculations and will lay it out during the scene's layout pass. If a managed node's layoutBounds changes, it will automatically trigger relayout up the scene-graph to the nearest layout root (which is typically the scene's root node).

      If the node is unmanaged, its parent will ignore the child in both preferred size computations and layout. Changes in layoutBounds will not trigger relayout above it. If an unmanaged node is of type Parent, it will act as a "layout root", meaning that calls to Parent.requestLayout() beneath it will cause only the branch rooted by the node to be relayed out, thereby isolating layout changes to that root and below. It's the application's responsibility to set the size and position of an unmanaged node.

      By default all nodes are managed.

    • isManaged

      public final boolean isManaged()
      Gets the value of the property managed.

    • setLayoutX

      public final void setLayoutX​(double value)
      Sets the value of the property layoutX.
      Property description:
      Defines the x coordinate of the translation that is added to this Node's transform for the purpose of layout. The value should be computed as the offset required to adjust the position of the node from its current layoutBounds minX position (which might not be 0) to the desired location.

      For example, if textnode should be positioned at finalX 

      
     textnode.setLayoutX(finalX - textnode.getLayoutBounds().getMinX());

      Failure to subtract layoutBounds minX may result in misplacement of the node. The relocate(x, y) method will automatically do the correct computation and should generally be used over setting layoutX directly.

      The node's final translation will be computed as layoutX + translateX, where layoutX establishes the node's stable position and translateX optionally makes dynamic adjustments to that position.

      If the node is managed and has a Region as its parent, then the layout region will set layoutX according to its own layout policy. If the node is unmanaged or parented by a Group, then the application may set layoutX directly to position it.

      Gets the value of the property layoutX.
      Property description:

      Property description:
      Defines the y coordinate of the translation that is added to this Node's transform for the purpose of layout. The value should be computed as the offset required to adjust the position of the node from its current layoutBounds minY position (which might not be 0) to the desired location.

    • relocate

      public void relocate​(double x, double y)
      Sets the node's layoutX and layoutY translation properties in order to relocate this node to the x,y location in the parent.

      This method does not alter translateX or translateY, which if also set will be added to layoutX and layoutY, adjusting the final location by corresponding amounts.

      Parameters:
      x - the target x coordinate location
      y - the target y coordinate location

    • isResizable

      public boolean isResizable()
      Indicates whether this node is a type which can be resized by its parent. If this method returns true, then the parent will resize the node (ideally within its size range) by calling node.resize(width,height) during the layout pass. All Regions, Controls, and WebView are resizable classes which depend on their parents resizing them during layout once all sizing and CSS styling information has been applied.

      If this method returns false, then the parent cannot resize it during layout (resize() is a no-op) and it should return its layoutBounds for minimum, preferred, and maximum sizes. Group, Text, and all Shapes are not resizable and hence depend on the application to establish their sizing by setting appropriate properties (e.g. width/height for Rectangle, text on Text, and so on). Non-resizable nodes may still be relocated during layout.

      Returns:
      whether or not this node type can be resized by its parent during layout
      See Also:
      getContentBias(), minWidth(double), minHeight(double), prefWidth(double), prefHeight(double), maxWidth(double), maxHeight(double), resize(double, double), getLayoutBounds()

    • getContentBias

      public Orientation getContentBias()
      Returns the orientation of a node's resizing bias for layout purposes. If the node type has no bias, returns null. If the node is resizable and it's height depends on its width, returns HORIZONTAL, else if its width depends on its height, returns VERTICAL.

      Resizable subclasses should override this method to return an appropriate value.

      Returns:
      orientation of width/height dependency or null if there is none
      See Also:
      isResizable(), minWidth(double), minHeight(double), prefWidth(double), prefHeight(double), maxWidth(double), maxHeight(double)

    • minWidth

      public double minWidth​(double height)
      Returns the node's minimum width for use in layout calculations. If the node is resizable, its parent should not resize its width any smaller than this value. If the node is not resizable, returns its layoutBounds width.

      Layout code which calls this method should first check the content-bias of the node. If the node has a vertical content-bias, then callers should pass in a height value that the minimum width should be based on. If the node has either a horizontal or null content-bias, then the caller should pass in -1.

      Node subclasses with a vertical content-bias should honor the height parameter whether -1 or a positive value. All other subclasses may ignore the height parameter (which will likely be -1).

      If Node's maxWidth(double) is lower than this number, minWidth takes precedence. This means the Node should never be resized below minWidth.

      Parameters:
      height - the height that should be used if minimum width depends on it
      Returns:
      the minimum width that the node should be resized to during layout. The result will never be NaN, nor will it ever be negative.
      See Also:
      isResizable(), getContentBias()

    • minHeight

      public double minHeight​(double width)
      Returns the node's minimum height for use in layout calculations. If the node is resizable, its parent should not resize its height any smaller than this value. If the node is not resizable, returns its layoutBounds height.

      Layout code which calls this method should first check the content-bias of the node. If the node has a horizontal content-bias, then callers should pass in a width value that the minimum height should be based on. If the node has either a vertical or null content-bias, then the caller should pass in -1.

      Node subclasses with a horizontal content-bias should honor the width parameter whether -1 or a positive value. All other subclasses may ignore the width parameter (which will likely be -1).

      If Node's maxHeight(double) is lower than this number, minHeight takes precedence. This means the Node should never be resized below minHeight.

      Parameters:
      width - the width that should be used if minimum height depends on it
      Returns:
      the minimum height that the node should be resized to during layout The result will never be NaN, nor will it ever be negative.

    • prefWidth

      public double prefWidth​(double height)
      Returns the node's preferred width for use in layout calculations. If the node is resizable, its parent should treat this value as the node's ideal width within its range. If the node is not resizable, just returns its layoutBounds width, which should be treated as the rigid width of the node.

      Layout code which calls this method should first check the content-bias of the node. If the node has a vertical content-bias, then callers should pass in a height value that the preferred width should be based on. If the node has either a horizontal or null content-bias, then the caller should pass in -1.

      Node subclasses with a vertical content-bias should honor the height parameter whether -1 or a positive value. All other subclasses may ignore the height parameter (which will likely be -1).

      Parameters:
      height - the height that should be used if preferred width depends on it
      Returns:
      the preferred width that the node should be resized to during layout The result will never be NaN, nor will it ever be negative.
      See Also:
      isResizable(), getContentBias(), autosize()

    • prefHeight

      public double prefHeight​(double width)
      Returns the node's preferred height for use in layout calculations. If the node is resizable, its parent should treat this value as the node's ideal height within its range. If the node is not resizable, just returns its layoutBounds height, which should be treated as the rigid height of the node.

      Layout code which calls this method should first check the content-bias of the node. If the node has a horizontal content-bias, then callers should pass in a width value that the preferred height should be based on. If the node has either a vertical or null content-bias, then the caller should pass in -1.

      Node subclasses with a horizontal content-bias should honor the height parameter whether -1 or a positive value. All other subclasses may ignore the height parameter (which will likely be -1).

      Parameters:
      width - the width that should be used if preferred height depends on it
      Returns:
      the preferred height that the node should be resized to during layout The result will never be NaN, nor will it ever be negative.

      getContentBias(), autosize()

    • maxWidth

      public double maxWidth​(double height)
      Returns the node's maximum width for use in layout calculations. If the node is resizable, its parent should not resize its width any larger than this value. A value of Double.MAX_VALUE indicates the parent may expand the node's width beyond its preferred without limits.

      If the node is not resizable, returns its layoutBounds width.

      Layout code which calls this method should first check the content-bias of the node. If the node has a vertical content-bias, then callers should pass in a height value that the maximum width should be based on. If the node has either a horizontal or null content-bias, then the caller should pass in -1.

      Node subclasses with a vertical content-bias should honor the height parameter whether -1 or a positive value. All other subclasses may ignore the height parameter (which will likely be -1).

      If Node's minWidth(double) is greater, it should take precedence over the maxWidth. This means the Node should never be resized below minWidth.

      Parameters:
      height - the height that should be used if maximum width depends on it
      Returns:
      the maximum width that the node should be resized to during layout The result will never be NaN, nor will it ever be negative.
      See Also:
      isResizable(), getContentBias()

    • maxHeight

      public double maxHeight​(double width)
      Returns the node's maximum height for use in layout calculations. If the node is resizable, its parent should not resize its height any larger than this value. A value of Double.MAX_VALUE indicates the parent may expand the node's height beyond its preferred without limits.

      If the node is not resizable, returns its layoutBounds height.

      Layout code which calls this method should first check the content-bias of the node. If the node has a horizontal content-bias, then callers should pass in a width value that the maximum height should be based on. If the node has either a vertical or null content-bias, then the caller should pass in -1.

      Node subclasses with a horizontal content-bias should honor the width parameter whether -1 or a positive value. All other subclasses may ignore the width parameter (which will likely be -1).

      If Node's minHeight(double) is greater, it should take precedence over the maxHeight. This means the Node should never be resized below minHeight.

      Parameters:
      width - the width that should be used if maximum height depends on it
      Returns:
      the maximum height that the node should be resized to during layout The result will never be NaN, nor will it ever be negative.

    • resize

      public void resize​(double width, double height)
      If the node is resizable, will set its layout bounds to the specified width and height. If the node is not resizable, this method is a no-op.

      This method should generally only be called by parent nodes from their layoutChildren() methods. All Parent classes will automatically resize resizable children, so resizing done directly by the application will be overridden by the node's parent, unless the child is unmanaged.

      Parents are responsible for ensuring the width and height values fall within the resizable node's preferred range. The autosize() method may be used if the parent just needs to resize the node to its preferred size.

      Parameters:
      width - the target layout bounds width
      height - the target layout bounds height
      See Also:
      isResizable(), getContentBias(), autosize(), minWidth(double), minHeight(double), prefWidth(double), prefHeight(double), maxWidth(double), maxHeight(double), getLayoutBounds()

    • autosize

      public final void autosize()
      If the node is resizable, will set its layout bounds to its current preferred width and height. If the node is not resizable, this method is a no-op.

      This method automatically queries the node's content-bias and if it's horizontal, will pass in the node's preferred width to get the preferred height; if vertical, will pass in the node's preferred height to get the width, and if null, will compute the preferred width/height independently.

      See Also:
      isResizable(), getContentBias()

    • resizeRelocate

      public void resizeRelocate​(double x, double y, double width, double height)
      If the node is resizable, will set its layout bounds to the specified width and height. If the node is not resizable, the resize step is skipped.

      Once the node has been resized (if resizable) then sets the node's layoutX and layoutY translation properties in order to relocate it to x,y in the parent's coordinate space.

      This method should generally only be called by parent nodes from their layoutChildren() methods. All Parent classes will automatically resize resizable children, so resizing done directly by the application will be overridden by the node's parent, unless the child is unmanaged.

      Parents are responsible for ensuring the width and height values fall within the resizable node's preferred range. The autosize() and relocate() methods may be used if the parent just needs to resize the node to its preferred size and reposition it.

      Parameters:
      x - the target x coordinate location
      y - the target y coordinate location
      width - the target layout bounds width
      height - the target layout bounds height

    • getBaselineOffset

      public double getBaselineOffset()
      The 'alphabetic' (or 'roman') baseline offset from the node's layoutBounds.minY location that should be used when this node is being vertically aligned by baseline with other nodes. By default this returns BASELINE_OFFSET_SAME_AS_HEIGHT for resizable Nodes and layoutBounds height for non-resizable. Subclasses which contain text should override this method to return their actual text baseline offset.
      Returns:
      offset of text baseline from layoutBounds.minY for non-resizable Nodes or BASELINE_OFFSET_SAME_AS_HEIGHT otherwise

    • computeAreaInScreen

      public double computeAreaInScreen()

      public final Bounds getBoundsInParent()
      Gets the value of the property boundsInParent.
      Property description:
      The rectangular bounds of this Node in the parent coordinate system. boundsInParent is calculated by taking the local bounds and applying the node transforms as specified in the Transformations section of the class doc.

      The resulting bounds will be conceptually in the coordinate space of the Node's parent, however, the node need not have a parent to calculate these bounds.

      Note that this method does not take the node's visibility into account; the computation is based on the geometry of this Node only.

      This property will always have a non-null value.

      Note that boundsInParent is automatically recomputed whenever the geometry of a node changes, or when any of the following the change: transforms ObservableList, any of the translate, layout or scale variables, or the rotate variable. For this reason, it is an error to bind any of these values in a node to an expression that depends upon this variable. For example, the x or y variables of a shape, or translateX, translateY should never be bound to boundsInParent for the purpose of positioning the node.

    • getLayoutBounds

      public final Bounds getLayoutBounds()
      Gets the value of the property layoutBounds.
      Property description:
      The rectangular bounds that should be used for layout calculations for this node. layoutBounds may differ from the visual bounds of the node and is computed differently depending on the node type.

      If the node type is resizable (Region, Control, or WebView) then the layoutBounds will always be 0,0 width x height. If the node type is not resizable (Shape, Text, or Group), then the layoutBounds are computed based on the node's geometric properties and does not include the node's clip, effect, or transforms. See individual class documentation for details.

      Note that the layoutX, layoutY, translateX, and translateY variables are not included in the layoutBounds. This is important because layout code must first determine the current size and location of the node (using layoutBounds) and then set layoutX and layoutY to adjust the translation of the node so that it will have the desired layout position.

      Because the computation of layoutBounds is often tied to a node's geometric variables, it is an error to bind any such variables to an expression that depends upon layoutBounds. For example, the x or y variables of a shape should never be bound to layoutBounds for the purpose of positioning the node.

      Note that for 3D shapes, the layout bounds is actually a rectangular box with X, Y, and Z values, although only X and Y are used in layout calculations.

      The layoutBounds will never be null.

    • viewOrderProperty

      public final DoubleProperty viewOrderProperty()
      Defines the rendering and picking order of this Node within its parent.

      This property is used to alter the rendering and picking order of a node within its parent without reordering the parent's children list. For example, this can be used as a more efficient way to implement transparency sorting. To do this, an application can assign the viewOrder value of each node to the computed distance between that node and the viewer.

      The parent will traverse its children in decreasing viewOrder order. This means that a child with a lower viewOrder will be in front of a child with a higher viewOrder. If two children have the same viewOrder, the parent will traverse them in the order they appear in the parent's children list.

      However, viewOrder does not alter the layout and focus traversal order of this Node within its parent. A parent always traverses its children list in order when doing layout or focus traversal.

      Default value:
      0.0

      public final void fireEvent​(Event event)
      Fires the specified event. By default the event will travel through the hierarchy from the stage to this node. Any event filter encountered will be notified and can consume the event. If not consumed by the filters, the event handlers on this node are notified. If these don't consume the event either, the event will travel back the same path it arrived to this node. All event handlers encountered are called and can consume the event.

      This method must be called on the FX user thread.

      Parameters:
      event - the event to fire

      public final void pseudoClassStateChanged​(PseudoClass pseudoClass, boolean active)
      Used to specify that a pseudo-class of this Node has changed. If the pseudo-class is used in a CSS selector that matches this Node, CSS will be reapplied. Typically, this method is called from the invalidated method of a property that is used as a pseudo-class. For example: 
      

     private static final PseudoClass MY_PSEUDO_CLASS_STATE = PseudoClass.getPseudoClass("my-state");

     BooleanProperty myPseudoClassState = new BooleanPropertyBase(false) {

           @Override public void invalidated() {

      JavaFX 8.0

    • applyCss

      public final void applyCss()
      If required, apply styles to this Node and its children, if any. This method does not normally need to be invoked directly but may be used in conjunction with Parent.layout() to size a Node before the next pulse, or if the Scene is not in a Stage.

      Provided that the Node's Scene is not null, CSS is applied to this Node regardless of whether this Node's CSS state is clean. CSS styles are applied from the top-most parent of this Node whose CSS state is other than clean, which may affect the styling of other nodes. This method is a no-op if the Node is not in a Scene. The Scene does not have to be in a Stage.

      This method does not invoke the Parent.layout() method. Typically, the caller will use the following sequence of operations.

      
     parentNode.applyCss();
     parentNode.layout();

      As a more complete example, the following code uses applyCss() and layout() to find the width and height of the Button before the Stage has been shown. If either the call to applyCss() or the call to layout() is commented out, the calls to getWidth() and getHeight() will return zero (until some time after the Stage is shown). 

      
 @Override
 public void start(Stage stage) throws Exception {

    Group root = new Group();
    Scene scene = new Scene(root);

    Button button = new Button("Hello World");
    root.getChildren().add(button);

    root.applyCss();
    root.layout();

    double width = button.getWidth();
    double height = button.getHeight();

    System.out.println(width + ", " + height);

    stage.setScene(scene);
    stage.show();
 }
