ToolBarSkin
Creates a new ToolBarSkin instance, installing the necessary child nodes into the Controlchildren
list, as well as the necessary input mappings for handling key, mouse, etc events.- Parameters:
control
- The control that this skin should be installed onto.
-
-
Method Details
-
dispose
public void dispose()Called by a Skinnable when the Skin is replaced on the Skinnable. This method allows a Skin to implement any logic necessary to clean up itself after the Skin is no longer needed. It may be used to release native resources. The methodsSkin.getSkinnable()
andSkin.getNode()
should return null following a call to dispose. Calling dispose twice has no effect. -
computeMinWidth
protected double computeMinWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)Computes the minimum allowable width of the Skin, based on the provided height.- Overrides:
computeMinWidth
in classSkinBase<ToolBar>
- Parameters:
height
- The height of the Skin, in case this value might dictate the minimum width.topInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- the pixel snapped left inset- Returns:
- A double representing the minimum width of this Skin.
-
computeMinHeight
protected double computeMinHeight(double width, double topInset, double rightInset, double bottomInset, double leftInset)Computes the minimum allowable height of the Skin, based on the provided width.- Overrides:
computeMinHeight
in classSkinBase<ToolBar>
- Parameters:
width
- The width of the Skin, in case this value might dictate the minimum height.topInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- the pixel snapped left inset- Returns:
- A double representing the minimum height of this Skin.
-
computePrefWidth
protected double computePrefWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)Calculates the preferred width of thisSkinBase
. The default implementation calculates this width as the width of the area occupied by its managed children when they are positioned at their current positions at their preferred widths.- Overrides:
computePrefWidth
in classSkinBase<ToolBar>
- Parameters:
height
- the height that should be used if preferred width depends on ittopInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- the pixel snapped left inset- Returns:
- the calculated preferred width
-
computePrefHeight
protected double computePrefHeight(double width, double topInset, double rightInset, double bottomInset, double leftInset)Calculates the preferred height of thisSkinBase
. The default implementation calculates this height as the height of the area occupied by its managed children when they are positioned at their current positions at their preferred heights.- Overrides:
computePrefHeight
in classSkinBase<ToolBar>
- Parameters:
width
- the width that should be used if preferred height depends on ittopInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- the pixel snapped left inset- Returns:
- the calculated preferred height
-
computeMaxWidth
protected double computeMaxWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)Computes the maximum allowable width of the Skin, based on the provided height.- Overrides:
computeMaxWidth
in classSkinBase<ToolBar>

- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- the pixel snapped left inset- Returns:
- A double representing the maximum width of this Skin.
-
computeMaxHeight
protected double computeMaxHeight(double width, double topInset, double rightInset, double bottomInset, double leftInset)Computes the maximum allowable height of the Skin, based on the provided width.- Overrides:
computeMaxHeight
in classSkinBase<ToolBar>
- Parameters:
width
- The width of the Skin, in case this value might dictate the maximum height.topInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset

- the pixel snapped left inset- Returns:
- A double representing the maximum height of this Skin.
-
layoutChildren
protected void layoutChildren(double x, double y, double w, double h)Called during the layout pass of the scenegraph.- Overrides:
layoutChildren
in classSkinBase<ToolBar>
- Parameters:
x
- the x positiony
- the y positionw
- the widthh
- the height
-
getClassCssMetaData
Returns the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.- Returns:
- the CssMetaData associated with this class, which may include the CssMetaData of its superclasses
-
getCssMetaData
This method should delegate toNode.getClassCssMetaData()
so that a Node's CssMetaData can be accessed without the need for reflection.- Overrides:
getCssMetaData
in classSkinBase<ToolBar>
- Returns:
- The CssMetaData associated with this node, which may include the CssMetaData of its superclasses.
-
queryAccessibleAttribute
Description copied from class:SkinBase
This method is called by the assistive technology to request the value for an attribute.This method is commonly overridden by subclasses to implement attributes that are required for a specific role.
If a particular attribute is not handled, the superclass implementation must be called.- Overrides:
queryAccessibleAttribute
in classSkinBase<ToolBar>
- Parameters:
attribute
- the requested attributeparameters
- optional list of parameters- Returns:
- the value for the requested attribute
- See Also:
AccessibleAttribute
,Node.queryAccessibleAttribute(javafx.scene.AccessibleAttribute, java.lang.Object...)
-
executeAccessibleAction
Description copied from class:SkinBase
This method is called by the assistive technology to request the action indicated by the argument should be executed.This method is commonly overridden by subclasses to implement action that are required for a specific role.
If a particular action is not handled, the superclass implementation must be called.- Overrides:
executeAccessibleAction
in classSkinBase<ToolBar>
- Parameters:
action
- the action to executeparameters
- optional list of parameters- See Also:
