      • getMenuPosition

        public Point2D getMenuPosition​()
        Returns the position to be used for a context menu, based on the location of the caret handle or selection handles. This is supported only on touch displays and does not use the location of the mouse.
        Overrides:
        getMenuPosition in class TextInputControlSkin<TextArea>
        Returns:
        the position to be used for this context menu

      • 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<T extends TextInputControl>
        Overrides:
        dispose in class SkinBase<TextArea>
