Constructor Details

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(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

Parameters:

g - the Graphics object used for painting

c - the component being painted

See Also:

• BasicListUI.paint(Graphics, JComponent)

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

installListeners

protected void installListeners()

Creates and installs the listeners for the JList, its model, and its selectionModel. This method is called at installUI() time.

Overrides:

installListeners in class BasicListUI

See Also:

• BasicListUI.installUI(JComponent)
• BasicListUI.uninstallListeners()

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.

uninstallListeners

protected void uninstallListeners()

Removes the listeners from the JList, its model, and its selectionModel. All of the listener fields, are reset to null here. This method is called at uninstallUI() time, it should be kept in sync with installListeners.

Overrides:

uninstallListeners in class BasicListUI

See Also:

• BasicListUI.uninstallUI(JComponent)
• BasicListUI.installListeners()

installDefaults

protected void installDefaults()

Initializes list properties such as font, foreground, and background, and adds the CellRendererPane. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.

Overrides:

installDefaults in class BasicListUI

See Also:

• BasicListUI.uninstallDefaults()
• BasicListUI.installUI(JComponent)
• CellRendererPane

uninstallDefaults

protected void uninstallDefaults()

• BasicListUI.installDefaults()
• BasicListUI.uninstallUI(JComponent)
• CellRendererPane

getContext

public SynthContext getContext(JComponent c)

Returns the Context for the specified component.
