installUI
public void installUI(JComponent c)
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:
- 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
LayoutManager
on the component if necessary. - Create/add any required sub-components to the component.
- Create/install event listeners on the component.
- Create/install a
PropertyChangeListener
on 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:
-
installUI
in classComponentUI
- Parameters:
-
c
- the component where this UI delegate is being installed - See Also:

,JComponent.setUI(javax.swing.plaf.ComponentUI)
,JComponent.updateUI()
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:
- 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 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:
-

,JComponent.updateUI()
installDefaults
protected void installDefaults(JRootPane c)
installComponents
protected void installComponents(JRootPane root)

uninstallKeyboardActions
protected void uninstallKeyboardActions(JRootPane root)
propertyChange
public void propertyChange(PropertyChangeEvent e)
Invoked when a property changes on the root pane. If the event indicates the defaultButton
has changed, this will reinstall the keyboard actions.
- Specified by:
-
propertyChange
in interfacePropertyChangeListener
- Parameters:
-
e
- A PropertyChangeEvent object describing the event source and the property that has changed.
