- The control for which this Skin should attach to.

Method Details
-
getSkinnable
Gets the Skinnable to which this Skin is assigned. A Skin must be created for one and only one Skinnable. This value will only ever go from a non-null to null value when the Skin is removed from the Skinnable, and only as a consequence of a call toSkin.dispose()
.The caller who constructs a Skinnable must also construct a Skin and properly establish the relationship between the Control and its Skin.
- Specified by:
getSkinnable
in interfaceSkin<C extends Control>
- Returns:
- A non-null Skinnable, or null value if disposed.
-
getNode
Gets the Node which represents this Skin. This must never be null, except after a call toSkin.dispose()
, and must never change except when changing to null. -
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()

should return null following a call to dispose. Calling dispose twice has no effect. -

instances will be executed in the order in which they are registered.- Parameters:
property
- the propertyconsumer
- the consumer
-
unregisterChangeListeners

.- Parameters:
property
- The property for which all listeners should be removed.- Returns:

,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 skin, 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:
child
- the child being positioned within this skinareaX
- the horizontal offset of the layout area relative to this skinareaY
- the vertical offset of the layout area relative to this skinareaWidth

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

,areaY
,areaWidth
xareaHeight
, with a baseline offset relative to that area.If the child is resizable, this method will use
fillWidth
andfillHeight
to determine whether to resize it to fill the area or keep the child at its preferred dimension. If fillWidth/fillHeight are true, then this method will only resize the child up to its max size limits. 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 and then pass that value to compute the child's height. If child's contentBias is vertical, then it will set its height first and pass that value to compute the child's width.
