Description copied from interface: SynthUI
Returns the Context for the specified component.

Specified by:
getContext in interface SynthUI
Parameters:
c - Component requesting SynthContext.
Returns:
SynthContext describing component.

createDefaultCellEditor

protected TreeCellEditor createDefaultCellEditor()
Description copied from class: BasicTreeUI

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,

Parameters:
context - a component context
g - Graphics to paint on
