        public static ComponentUI createUI​(JComponent c)
        Returns a UI.

      • update

        public void update​(Graphics g,
                           JComponent c)
        Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls the paint(SynthContext,Graphics) method.

        In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the paint method.

        Overrides:
        update in class ComponentUI
        Parameters:
        g - the Graphics object used for painting
        c - the component being painted

        Paints the specified component.
        Parameters:
        context - context for the component being painted
