Method Detail

createUI

@NotNull
public static ComponentUI createUI(@NotNull
                                            JComponent c)

Returns an instance of the WebLabelUI for the specified component. This tricky method is used by UIManager to create component UIs when needed.

Parameters:

c - component that will use UI instance

Returns:

instance of the WebLabelUI

installUI

public void installUI(@NotNull
                      JComponent c)

Description copied from interface: WebUI

Configures the specified component appropriate 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 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.
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.

Specified by:

installUI in interface WebUI<C extends JLabel>

Overrides:

installUI in class WLabelUI<C extends JLabel>

Parameters:

c - the component where this UI delegate is being installed

uninstallUI

public void uninstallUI(@NotNull
                        JComponent c)

Description copied from interface: WebUI

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.

Specified by:

uninstallUI in interface WebUI<C extends JLabel>

Overrides:

uninstallUI in class WLabelUI<C extends JLabel>

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
