Method Details

createUI

public static ComponentUI createUI(JComponent list)

Creates a new UI object for the given component.

Parameters:

list - 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 BasicListUI.paint(Graphics, JComponent) 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

g - the Graphics object used for painting

c - the component being painted

See Also:

• BasicListUI.paint(Graphics, JComponent)

paintBorder

 int y,
 int w,
 int h)

Paints the border.

h - height of the border

propertyChange

public void propertyChange(PropertyChangeEvent e)

This method gets called when a bound property is changed.

Specified by:

Parameters:

e - A PropertyChangeEvent object describing the event source and the property that has changed.

getContext

public SynthContext getContext(JComponent c)

Returns the Context for the specified component.

Specified by:

getContext in interface SynthUI
