public void installUI(JComponent c)

Overrides javax.swing.plaf.basic.BasicPanelUI.installUI.

Doc from javax.swing.plaf.ComponentUI.installUI.

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.

public void paint(Graphics g, JComponent c)

Overrides javax.swing.plaf.ComponentUI.paint.

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.

Parameters
g:Graphics

the Graphics object used for painting

c:JComponent

the component being painted

public void uninstallUI(JComponent c)

Overrides javax.swing.plaf.basic.BasicPanelUI.uninstallUI.

Doc from javax.swing.plaf.ComponentUI.uninstallUI.

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.
Annotations
@Override
updateback to summary
public void update(Graphics g, JComponent c)

Overrides javax.swing.plaf.ComponentUI.update.

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.

Parameters
g:Graphics

the Graphics object used for painting

c:JComponent

the component being painted
