Constructor Summary
Constructors Constructor Description TabPaneSkin(TabPane control)
Creates a new TabPaneSkin instance, installing the necessary child nodes into the Controlchildren
list, as well as the necessary input mappings for handling key, mouse, etc events. -

dispose()
Called by a Skinnable when the Skin is replaced on the Skinnable.static List<CssMetaData<? extends Styleable,?>>
getClassCssMetaData()
Returns the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.List<CssMetaData<? extends Styleable,?>>

TabPaneSkin
Creates a new TabPaneSkin 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. -
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<TabPane>
- 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<TabPane>
- 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
-
computeBaselineOffset
public double computeBaselineOffset(double topInset, double rightInset, double bottomInset, double leftInset)Calculates the baseline offset based on the first managed child. If there is no such child, returnsNode.getBaselineOffset()
.- Overrides:
computeBaselineOffset
in classSkinBase<TabPane>
- Parameters:
topInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- the pixel snapped left inset- Returns:
- baseline offset
-
layoutChildren
protected void layoutChildren(double x, double y, double w, double h)Called during the layout pass of the scenegraph.- Overrides:
layoutChildren
in classSkinBase<TabPane>
- 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<TabPane>
- 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<TabPane>
- Parameters:
attribute
- the requested attributeparameters
- optional list of parameters- Returns:
- the value for the requested attribute
- See Also:
