computePrefHeightback to summary
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

Annotations

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

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.

Annotations
@Override
installback to summary
public void install()

Overrides default javafx.scene.control.Skin.install.

Doc from javafx.scene.control.Skin.install.

Called once when Skin is set. This method is called after the previous skin, if any, has been uninstalled via its dispose() method. The skin can now safely make changes to its associated control, like registering listeners, adding child nodes, and modifying properties and event handlers.

Application code must not call this method.

The default implementation of this method does nothing.

Doc from javafx.scene.control.SkinBase.layoutChildren.

Called during the layout pass of the scenegraph.

Parameters
x:double

y:double

the y position

w:double

the width

h:double
