    • Constructor Detail

      • MenuButtonSkinBase

        public MenuButtonSkinBase​(C control)
        Creates a new instance of MenuButtonSkinBase, although note that this instance does not handle any behavior / input mappings - this needs to be handled appropriately by subclasses.
        Parameters:
        control - The control that this skin should be installed onto.
    • Method Detail

      • 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 methods Skin.getSkinnable() and Skin.getNode() should return null following a call to dispose. Calling dispose twice has no effect.
        Specified by:
        dispose in interface Skin<C extends MenuButton>
        Overrides:
        dispose in class SkinBase<C extends MenuButton>
