BasicColorChooserUI
-

installUI
public void installUI(JComponent c)
Description copied from class:ComponentUIConfigures the specified component appropriately for the look and feel. This method is invoked when theComponentUIinstance 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 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
LayoutManageron the component if necessary. - Create/add any required sub-components to the component.
- Create/install event listeners on the component.
- Create/install a
PropertyChangeListeneron 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.
- Overrides:
installUIin classComponentUI- Parameters:
c- the component where this UI delegate is being installed- See Also:
ComponentUI.uninstallUI(javax.swing.JComponent),JComponent.setUI(javax.swing.plaf.ComponentUI),JComponent.updateUI()
-
uninstallUI
public void uninstallUI(JComponent c)
Description copied from class:ComponentUIReverses configuration which was done on the specified component duringinstallUI. This method is invoked when thisUIComponentinstance is being removed as the UI delegate for the specified component. This method should undo the configuration performed ininstallUI, being careful to leave theJComponentinstance 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:
uninstallUIin classComponentUI- 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()
