Constructor Detail

SynthMenuUI

public SynthMenuUI()

Method Detail

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)

Description copied from class: ComponentUI

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

See Also:

ComponentUI.installUI(javax.swing.JComponent), JComponent.updateUI()

uninstallDefaults

protected void uninstallDefaults()

Overrides:

uninstallDefaults in class BasicMenuUI

uninstallListeners

protected void uninstallListeners()

Overrides:

uninstallListeners in class BasicMenuUI

getContext

public SynthContext getContext(JComponent c)

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.

getPreferredMenuItemSize

protected Dimension getPreferredMenuItemSize(JComponent c,
                                             Icon checkIcon,
                                             Icon arrowIcon,
                                             int defaultTextIconGap)

Overrides:

getPreferredMenuItemSize in class BasicMenuItemUI

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 BasicMenuItemUI

Parameters:

g - the Graphics object used for painting

c - the component being painted

See Also:

paint(SynthContext,Graphics)

paint

public void paint(Graphics g,
                  JComponent c)

Paints the specified component according to the Look and Feel.

This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics) method.

Overrides:

paint in class BasicMenuItemUI

Parameters:

g - the Graphics object used for painting

c - the component being painted

See Also:

paint(SynthContext,Graphics)

paint

protected void paint(SynthContext context,
                     Graphics g)

Paints the specified component. This implementation does nothing.

Parameters:

context - context for the component being painted

g - the Graphics object used for painting

See Also:

update(Graphics,JComponent)

paintBorder

public void paintBorder(SynthContext context,
                        Graphics g,
                        int x,
                        int y,
                        int w,
                        int h)

Description copied from interface: SynthUI

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)

Description copied from interface: PropertyChangeListener

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.
