Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

public static ComponentUI createUI (JComponent c)

public void installUI (JComponent c)

Configures the specified component appropriate for the look and feel. This method is invoked when the ComponentUI instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:

Install any default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
Install a LayoutManager on the component if necessary.
Create/add any required sub-components to the component.
Create/install event listeners on the component.
Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
Install keyboard UI (mnemonics, traversal, etc.) on the component.
Initialize any appropriate instance data.

Parameters

c	the component where this UI delegate is being installed

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:

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

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

public void update (Graphics g, JComponent c)

If necessary paints the background of the component, then invokes paint.

Parameters

g	Graphics to paint to
c	JComponent painting on

Throws

NullPointerException	if `g` or `c` is null

Protected Methods

protected ContainerListener createContainerListener ()

Creates a container listener that will be added to the JToolBar. If this method returns null then it will not be added to the toolbar.

Returns

an instance of a ContainerListener or null

protected MouseInputListener createDockingListener ()

protected Border createNonRolloverBorder ()

Creates the non rollover border for toolbar components. This border will be installed as the border for components added to the toolbar if rollover borders are not enabled.

Override this method to provide an alternate rollover border.

protected Border createRolloverBorder ()

Creates a rollover border for toolbar components. The rollover border will be installed if rollover borders are enabled.

Override this method to provide an alternate rollover border.

protected PropertyChangeListener createRolloverListener ()

Creates a property change listener that will be added to the JToolBar. If this method returns null then it will not be added to the toolbar.

Returns

an instance of a PropertyChangeListener or null

protected void installListeners ()

protected void setBorderToNonRollover (Component c)

Sets the border of the component to have a non-rollover border which was created by createNonRolloverBorder.

Parameters

c	component which will have a non-rollover border installed
