Method Detail

createUI

public static ComponentUI createUI(JComponent c)

Class is disabled.

Creates a new UI object for the given component.

Parameters:

c - component to create UI object for

Returns:

the UI object

installUI

public void installUI(JComponent c)

Class is disabled.

Description copied from class: ComponentUI

Configures the specified component appropriately 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:

1. Install 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.
2. Install a LayoutManager on the component if necessary.
3. Create/add any required sub-components to the component.
4. Create/install event listeners on the component.
5. Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
6. Install keyboard UI (mnemonics, traversal, etc.) on the component.
7. Initialize any appropriate instance data.

Overrides:

installUI in class ComponentUI

Parameters:

c - the component where this UI delegate is being installed

ComponentUI.uninstallUI(javax.swing.JComponent), JComponent.setUI(javax.swing.plaf.ComponentUI), JComponent.updateUI()

uninstallUI

public void uninstallUI(JComponent c)

Class is disabled.

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 ComponentUI

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()

installDefaults

protected void installDefaults(JComponent c)

Class is disabled.

Installs defaults for a viewport.

Parameters:

c - a JViewport object

installListeners

protected void installListeners(JComponent c)

Class is disabled.

Installs listeners into the viewport.

Parameters:

c - a JViewport object

uninstallListeners

protected void uninstallListeners(JComponent c)

Class is disabled.

Uninstalls listeners from the viewport.

Parameters:

c - a JViewport object

uninstallDefaults

protected void uninstallDefaults(JComponent c)

Class is disabled.

Uninstalls defaults from a viewport.

Parameters:

c - a JViewport object

getContext

public SynthContext getContext(JComponent c)

Class is disabled.

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.

update

public void update(Graphics g,
                   JComponent c)

Class is disabled.

Description copied from class: ComponentUI

Notifies this UI delegate that it is time to paint the specified component. This method is invoked by JComponent when the specified component is being painted.

By default this method fills the specified component with its background color if its opaque property is true, and then immediately calls paint. In general this method need not 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 context in which to paint

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

See Also:

ComponentUI.paint(java.awt.Graphics, javax.swing.JComponent), JComponent.paintComponent(java.awt.Graphics)

paintBorder

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

Class is disabled.

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

paint

public void paint(Graphics g,
                  JComponent c)

Class is disabled.

Description copied from class: ComponentUI

Paints the specified component appropriately for the look and feel. This method is invoked from the ComponentUI.update method when the specified component is being painted. Subclasses should override this method and use the specified Graphics object to render the content of the component.

Overrides:

paint in class ComponentUI

Parameters:

g - the Graphics context in which to paint

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

See Also:

ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)

paint

protected void paint(SynthContext context,
                     Graphics g)

Class is disabled.

Paints the specified component. This implementation does nothing.

Parameters:

context - context for the component being painted

g - Graphics object used for painting

propertyChange

public void propertyChange(PropertyChangeEvent e)

Class is disabled.

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.
