protected double computePrefHeight(double width, double topInset, double rightInset, double bottomInset, double leftInset)

Overrides javafx.scene.control.SkinBase.computePrefHeight.

Doc from javafx.scene.control.SkinBase.computePrefHeight.

Calculates the preferred height of this SkinBase. 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.

Parameters
width:double

the width that should be used if preferred height depends on it

topInset:double

the pixel snapped top inset

rightInset:double

the pixel snapped right inset

bottomInset:double

the pixel snapped bottom inset

leftInset:double

the pixel snapped left inset

Returns:double

the calculated preferred height

protected double computePrefWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)

Overrides javafx.scene.control.SkinBase.computePrefWidth.

Doc from javafx.scene.control.SkinBase.computePrefWidth.

Calculates the preferred width of this SkinBase. 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.

Parameters
height:double

the height that should be used if preferred width depends on it

topInset:double

the pixel snapped top inset

rightInset:double

the pixel snapped right inset

bottomInset:double

the pixel snapped bottom inset

leftInset:double

the pixel snapped left inset

Returns:double

the calculated preferred width

Annotations
@Override
disposeback to summary
public void dispose()

Overrides javafx.scene.control.SkinBase.dispose.

Implements javafx.scene.control.Skin.dispose.

Doc from javafx.scene.control.SkinBase.dispose.

Called when a previously installed skin is about to be removed from its associated control. This allows the skin to do clean up, like removing listeners and bindings, and undo any changes to the control's properties. After this method completes, getSkinnable() and getNode() should return null.

Calling dispose() more than once has no effect.
