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 classBasicMenuUI
installListeners
protected void installListeners()
- Overrides:
-
installListeners
in classBasicMenuUI
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:
- 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.
- Overrides:
-
uninstallUI
in classBasicMenuItemUI
- 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 classBasicMenuUI
uninstallListeners
protected void uninstallListeners()
- Overrides:
-
uninstallListeners
in classBasicMenuUI
getContext
public SynthContext getContext(JComponent c)
Returns the Context for the specified component.
- Specified by:
-
getContext
in interfaceSynthUI
- Parameters:
-
c
- Component requesting SynthContext. - Returns:
- SynthContext describing component.
getPreferredMenuItemSize
protected Dimension getPreferredMenuItemSize(JComponent c, Icon checkIcon, Icon arrowIcon, int defaultTextIconGap)
- Overrides:
-
getPreferredMenuItemSize
in classBasicMenuItemUI
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 classBasicMenuItemUI
- Parameters:
-
g
- theGraphics
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 classBasicMenuItemUI
- Parameters:
-
g
- theGraphics
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
- theGraphics
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)
Paints the border.
- Specified by:
-
paintBorder
in interfaceSynthUI
- 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 interfacePropertyChangeListener
- Parameters:
-
e
