public class Region extends Parent
Every Region has its layout bounds, which are specified to be (0, 0, width, height). A Region might draw outside these bounds. The content area of a Region is the area which is occupied for the layout of its children. This area is, by default, the same as the layout bounds of the Region, but can be modified by either the properties of a border (either with BorderStrokes or BorderImages), and by padding. The padding can be negative, such that the content area of a Region might extend beyond the layout bounds of the Region, but does not affect the layout bounds.
A Region has a Background, and a Border, although either or both of these might be empty. The Background of a Region is made up of zero or more BackgroundFills, and zero or more BackgroundImages. Likewise, the border of a Region is defined by its Border, which is made up of zero or more BorderStrokes and zero or more BorderImages. All BackgroundFills are drawn first, followed by BackgroundImages, BorderStrokes, and finally BorderImages. The content is drawn above all backgrounds and borders. If a BorderImage is present (and loaded all images properly), then no BorderStrokes are actually drawn, although they are considered for computing the position of the content area (see the stroke width property of a BorderStroke). These semantics are in line with the CSS 3 specification. The purpose of these semantics are to allow an application to specify a fallback BorderStroke to be displayed in the case that an ImageStroke fails to download or load.
By default a Region appears as a Rectangle. A BackgroundFill radii might cause the Rectangle to appear rounded.
This affects not only making the visuals look like a rounded rectangle, but it also causes the picking behavior
of the Region to act like a rounded rectangle, such that locations outside the corner radii are ignored. A
Region can be made to use any shape, however, by specifying the shape
property. If a shape is specified,
then all BackgroundFills, BackgroundImages, and BorderStrokes will be applied to the shape. BorderImages are
not used for Regions which have a shape specified.
Although the layout bounds of a Region are not influenced by any Border or Background, the content area
insets and the picking area of the Region are. The insets
of the Region define the distance
between the edge of the layout bounds and the edge of the content area. For example, if the Region
layout bounds are (x=0, y=0, width=200, height=100), and the insets are (top=10, right=20, bottom=30, left=40),
then the content area bounds will be (x=40, y=10, width=140, height=60). A Region subclass which is laying
out its children should compute and honor these content area bounds.
By default a Region inherits the layout behavior of its superclass, Parent
,
which means that it will resize any resizable child nodes to their preferred
size, but will not reposition them. If an application needs more specific
layout behavior, then it should use one of the Region subclasses:
StackPane
, HBox
, VBox
, TilePane
, FlowPane
,
BorderPane
, GridPane
, or AnchorPane
.
To implement a more custom layout, a Region subclass must override
computePrefWidth
, computePrefHeight
, and
layoutChildren
. Note that layoutChildren
is called automatically
by the scene graph while executing a top-down layout pass and it should not be invoked directly by the
region subclass.
Region subclasses which layout their children will position nodes by setting
layoutX
/layoutY
and do not alter
translateX
/translateY
, which are reserved for
adjustments and animation.

Property Details
-
snapToPixel
Defines whether this region adjusts position, spacing, and size values of its children to pixel boundaries. This defaults to true, which is generally the expected behavior in order to have crisp user interfaces. A value of false will allow for fractional alignment, which may lead to "fuzzy" looking borders.- See Also:
isSnapToPixel()
,setSnapToPixel(boolean)
-
padding
The top, right, bottom, and left padding around the region's content. This space will be included in the calculation of the region's minimum and preferred sizes. By default, padding isInsets.EMPTY
. Setting the value tonull
should be avoided.- See Also:
getPadding()
,setPadding(Insets)
-
background
The background of the Region, which is made up of zero or more BackgroundFills, and zero or more BackgroundImages. It is possible for a Background to be empty, where it has neither fills nor images, and is semantically equivalent to null.- Since:
- JavaFX 8.0
- See Also:
getBackground()
,setBackground(Background)
-
border
The border of the Region, which is made up of zero or more BorderStrokes, and zero or more BorderImages. It is possible for a Border to be empty, where it has neither strokes nor images, and is semantically equivalent to null.- Since:
- JavaFX 8.0
- See Also:
getBorder()
,setBorder(Border)
-
opaqueInsets
Defines the area of the region within which completely opaque pixels are drawn. This is used for various performance optimizations. The pixels within this area MUST BE fully opaque, or rendering artifacts will result. It is the responsibility of the application, either via code or via CSS, to ensure that the opaqueInsets is correct for a Region based on the backgrounds and borders of that region. The values for each of the insets must be real numbers, not NaN or Infinity. If no known insets exist, then the opaqueInsets should be set to null.- Since:
- JavaFX 8.0
- See Also:
getOpaqueInsets()
,setOpaqueInsets(Insets)
-
insets
The insets of the Region define the distance from the edge of the region (its layout bounds, or (0, 0, width, height)) to the edge of the content area. All child nodes should be laid out within the content area. The insets are computed based on the Border which has been specified, if any, and also the padding.- Since:
- JavaFX 8.0
- See Also:
getInsets()
-
width
The width of this resizable node. This property is set by the region's parent during layout and may not be set by the application. If an application needs to explicitly control the size of a region, it should override its preferred size range by setting theminWidth
,prefWidth
, andmaxWidth
properties.- See Also:
getWidth()
,setWidth(double)
-
height
The height of this resizable node. This property is set by the region's parent during layout and may not be set by the application. If an application needs to explicitly control the size of a region, it should override its preferred size range by setting theminHeight
,prefHeight
, andmaxHeight
properties.- See Also:
getHeight()
,setHeight(double)
-
minWidth
Property for overriding the region's computed minimum width. This should only be set if the region's internally computed minimum width doesn't meet the application's layout needs.Defaults to the
USE_COMPUTED_SIZE
flag, which means thatminWidth(forHeight)
will return the region's internally computed minimum width.Setting this value to the
USE_PREF_SIZE
flag will causeminWidth(forHeight)
to return the region's preferred width, enabling applications to easily restrict the resizability of the region.- See Also:
getMinWidth()
,setMinWidth(double)
-
minHeight
Property for overriding the region's computed minimum height. This should only be set if the region's internally computed minimum height doesn't meet the application's layout needs.Defaults to the
USE_COMPUTED_SIZE
flag, which means thatminHeight(forWidth)
will return the region's internally computed minimum height.Setting this value to the
USE_PREF_SIZE
flag will causeminHeight(forWidth)
to return the region's preferred height, enabling applications to easily restrict the resizability of the region.- See Also:
getMinHeight()
,setMinHeight(double)
-
prefWidth
Property for overriding the region's computed preferred width. This should only be set if the region's internally computed preferred width doesn't meet the application's layout needs.Defaults to the
USE_COMPUTED_SIZE
flag, which means thatgetPrefWidth(forHeight)
will return the region's internally computed preferred width.- See Also:
getPrefWidth()
,setPrefWidth(double)
-
prefHeight
Property for overriding the region's computed preferred height. This should only be set if the region's internally computed preferred height doesn't meet the application's layout needs.Defaults to the
USE_COMPUTED_SIZE
flag, which means thatgetPrefHeight(forWidth)
will return the region's internally computed preferred width.- See Also:
getPrefHeight()
,setPrefHeight(double)
-
maxWidth
Property for overriding the region's computed maximum width. This should only be set if the region's internally computed maximum width doesn't meet the application's layout needs.Defaults to the
USE_COMPUTED_SIZE
flag, which means thatgetMaxWidth(forHeight)
will return the region's internally computed maximum width.Setting this value to the
USE_PREF_SIZE
flag will causegetMaxWidth(forHeight)
to return the region's preferred width, enabling applications to easily restrict the resizability of the region.- See Also:
getMaxWidth()
,setMaxWidth(double)
-
maxHeight
Property for overriding the region's computed maximum height. This should only be set if the region's internally computed maximum height doesn't meet the application's layout needs.Defaults to the
USE_COMPUTED_SIZE
flag, which means thatgetMaxHeight(forWidth)
will return the region's internally computed maximum height.Setting this value to the
USE_PREF_SIZE
flag will causegetMaxHeight(forWidth)
to return the region's preferred height, enabling applications to easily restrict the resizability of the region.- See Also:
getMaxHeight()
,setMaxHeight(double)
-
shape
When specified, theShape
will cause the region to be rendered as the specified shape rather than as a rounded rectangle. When null, the Region is rendered as a rounded rectangle. When rendered as a Shape, any Background is used to fill the shape, although any background insets are ignored as are background radii. Any BorderStrokes defined are used for stroking the shape. Any BorderImages are ignored.- Default value:
- null
- Since:
- JavaFX 8.0
- See Also:
getShape()
,setShape(Shape)
-
scaleShape
Specifies whether the shape, if defined, is scaled to match the size of the Region.true
means the shape is scaled to fit the size of the Region,false
means the shape is at its source size, its positioning depends on the value ofcenterShape
.- Default value:
- true
- Since:
- JavaFX 8.0
- See Also:
isScaleShape()
,setScaleShape(boolean)
-
centerShape
Defines whether the shape is centered within the Region's width or height.true
means the shape centered within the Region's width and height,false
means the shape is positioned at its source position.- Default value:
- true
- Since:
- JavaFX 8.0
- See Also:
isCenterShape()
,setCenterShape(boolean)
-
cacheShape
Defines a hint to the system indicating that the Shape used to define the region's background is stable and would benefit from caching.- Default value:
- true

layoutInArea
protected void layoutInArea(Node child, double areaX, double areaY, double areaWidth, double areaHeight, double areaBaselineOffset, HPos halignment, VPos valignment)Utility method which lays out the child within an area of this region defined byareaX
,areaY
,areaWidth
xareaHeight
, with a baseline offset relative to that area.If the child is resizable, this method will resize it to fill the specified area unless the node's maximum size prevents it. If the node's maximum size preference is less than the area size, the maximum size will be used. If node's maximum is greater than the area size, then the node will be resized to fit within the area, unless its minimum size prevents it.
If the child has a non-null contentBias, then this method will use it when resizing the child. If the contentBias is horizontal, it will set its width first to the area's width (up to the child's max width limit) and then pass that value to compute the child's height. If child's contentBias is vertical, then it will set its height to the area height (up to child's max height limit) and pass that height to compute the child's width. If the child's contentBias is null, then it's width and height have no dependencies on each other.
If the child is not resizable (Shape, Group, etc) then it will only be positioned and not resized.
If the child's resulting size differs from the area's size (either because it was not resizable or it's sizing preferences prevented it), then this function will align the node relative to the area using horizontal and vertical alignment values. If valignment is
VPos.BASELINE
then the node's baseline will be aligned with the area baseline offset parameter, otherwise the baseline parameter is ignored.If
snapToPixel
istrue
for this region, then the resulting x,y values will be rounded to their nearest pixel boundaries and the width/height values will be ceiled to the next pixel boundary.- Parameters:

getUserAgentStylesheet
An implementation may specify its own user-agent styles for this Region, and its children, by overriding this method. These styles are used in addition to whatever user-agent stylesheets are in use. This provides a mechanism for third parties to introduce styles for custom controls.The URL is a hierarchical URI of the form [scheme:][//authority][path]. If the URL does not have a [scheme:] component, the URL is considered to be the [path] component only. Any leading '/' character of the [path] is ignored and the [path] is treated as a path relative to the root of the application's classpath.
Subclasses overriding this method should not assume any particular implementation approach as to the number and frequency with which it is called. For this reason, attempting any kind of dynamic implementation (i.e. returning different user agent stylesheet values) based on some state change is highly discouraged, as there is no guarantee when, or even if, this method will be called. Some JavaFX CSS implementations may choose to cache this response for an indefinite period of time, and therefore there should be no expectation around when this method is called.
For additional information about using CSS with the scene graph, see the CSS Reference Guide.package com.example.javafx.app; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.stage.Stage; public class MyApp extends Application { @Override public void start(Stage stage) { Scene scene = new Scene(new Group()); scene.getStylesheets().add("/com/example/javafx/app/mystyles.css"); stage.setScene(scene); stage.show(); } public static void main(String[] args) { launch(args); } }
- Returns:
- A string URL
