Methods

createUI

public static ComponentUI createUI(JComponent x)

Creates a new UI object for the given component.

Parameters:

x - component to create UI object for

Returns:

the UI object

installDefaults

protected void installDefaults()

Overrides:

installDefaults in class BasicMenuUI

installListeners

protected void installListeners()

Overrides:

installListeners in class BasicMenuUI

uninstallUI

public void uninstallUI(JComponent c)

Reverses configuration which was done on the specified component during installUI. This method is invoked when this UIComponent instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed in installUI, being careful to leave the JComponent instance in a clean state (no extraneous listeners, look-and-feel-specific property objects, etc.). This should include the following:

1. Remove any UI-set borders from the component.
2. Remove any UI-set layout managers on the component.
3. Remove any UI-added sub-components from the component.
4. Remove any UI-added event/property listeners from the component.
5. Remove any UI-installed keyboard UI from the component.
6. Nullify any allocated instance data objects to allow for GC.

Overrides:

uninstallUI in class BasicMenuItemUI

Parameters:

c - the component from which this UI delegate is being removed; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
