      • createUI

        public static ComponentUI createUI​(JComponent c)
        Creates a new UI object for the given component.
        Parameters:
        c - component to create UI object for
        Returns:
        the UI object
      • installDefaults

        protected void installDefaults​(JComponent c)
        Installs defaults for a viewport.
        Parameters:
        c - a JViewport object
      • installListeners

        protected void installListeners​(JComponent c)
        Installs listeners into the viewport.
        Parameters:
        c - a JViewport object
      • uninstallListeners

        protected void uninstallListeners​(JComponent c)
        Uninstalls listeners from the viewport.
        Parameters:
        c - a JViewport object
      • uninstallDefaults

        protected void uninstallDefaults​(JComponent c)
        Uninstalls defaults from a viewport.
        Parameters:
        c - a JViewport object
      • 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
        See Also:
        paint(SynthContext,Graphics)
      • paintBorder

        public void paintBorder​(SynthContext context,
                                Graphics g,
                                int x,
                                int y,
                                int w,
                                int h)
        Paints the border. The method is never called, because the JViewport class does not support a border. This implementation does nothing.
        Specified by:
        paintBorder in interface SynthUI
        Parameters:
        context - a component context
        g - the Graphics to paint on
        x - the X coordinate
        y - the Y coordinate
        w - width of the border
        h - height of the border
      • paint

        protected void paint​(SynthContext context,
                             Graphics g)
        Paints the specified component. This implementation does nothing.
        Parameters:
        context - context for the component being painted
        g - the Graphics object used for painting
