public ContextMenuSkin(final ContextMenu control)

Creates a new ContextMenuSkin instance.

Parameters
control:ContextMenu

The control that this skin should be installed onto.

Method Detail

disposeback to summary
public void dispose()

Implements javafx.scene.control.Skin.dispose.

Doc from javafx.scene.control.Skin.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.

getNodeback to summary
public Node getNode()

Implements javafx.scene.control.Skin.getNode.

Doc from javafx.scene.control.Skin.getNode.

Gets the Node which represents this Skin. This must never be null, except after a call to dispose(), and must never change except when changing to null.

Annotations
@Override
getSkinnableback to summary
public ContextMenu getSkinnable()

Implements javafx.scene.control.Skin.getSkinnable.

Doc from javafx.scene.control.Skin.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 to dispose().

The caller who constructs a Skinnable must also construct a Skin and properly establish the relationship between the Control and its Skin.
