Method Detail

createUI

public static ComponentUI createUI(JComponent c)

installUI

public void installUI(JComponent comp)
Description copied from class: javax.swing.plaf.ComponentUI
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.

Overrides:
installUI in class ComponentUI
Parameters:
comp - the component where this UI delegate is being installed

uninstallUI

public void uninstallUI(JComponent comp)
Description copied from class: javax.swing.plaf.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:
  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.

Overrides:
uninstallUI in class ComponentUI
Parameters:
comp - 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()

update

public void update(Graphics g,
                   JComponent c)
Description copied from class: javax.swing.plaf.ComponentUI
Notifies this UI delegate that it's time to paint the specified component. This method is invoked by JComponent when the specified component is being painted. By default this method will fill the specified component with its background color (if its opaque property is true) and then immediately call paint. In general this method need not be overridden by subclasses; all look-and-feel rendering code should reside in the paint method.

Overrides:
update in class ComponentUI
Parameters:
g - the Graphics context in which to paint
c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
