SynthListUI

public SynthListUI()
Constructs a SynthListUI.

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(java.awt.Graphics, javax.swing.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
Parameters:
g - the Graphics object used for painting
c - the component being painted

paintBorder

public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)
Paints the border.
Specified by:
paintBorder in interface SynthUI
Parameters:
context - a component context
g - Graphics to paint on
x - the X coordinate
y - the Y coordinate
w - width of 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:
propertyChange in interface PropertyChangeListener
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:
