Methods

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

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)

paint

public void paint(Graphics g,
                  JComponent c)

This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics) method.

Overrides:
paint in class ComponentUI
Parameters:
g - the Graphics object used for painting
c - the component being painted
See Also:
paint(SynthContext,Graphics)
