Method Detail
-
createUI
public static javax.swing.plaf.ComponentUI createUI(javax.swing.JComponent c)
Returns an instance of the UI delegate for the specified component. Each subclass must provide its own staticcreateUI
method that returns an instance of that UI delegate subclass. If the UI delegate subclass is stateless, it may return an instance that is shared by multiple components. If the UI delegate is stateful, then it should return a new instance per component. The default implementation of this method throws an error, as it should never be invoked.
-
installUI
public void installUI(javax.swing.JComponent c)
Configures the specified component appropriate for the look and feel. This method is invoked when theComponentUI
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 any 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 classjavax.swing.plaf.ComponentUI
- Parameters:
c
- the component where this UI delegate is being installed- See Also:
uninstallUI(javax.swing.JComponent)
,JComponent.setUI(javax.swing.plaf.ComponentUI)
,JComponent.updateUI()
-
uninstallUI
public void uninstallUI(javax.swing.JComponent c)
Reverses configuration which was done on the specified component duringinstallUI
. This method is invoked when thisUIComponent
instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed ininstallUI
, being careful to leave theJComponent
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 classjavax.swing.plaf.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:
