public class BasicTitledPanelUI
extends TitledPanelUI

All TitledPanels contain a title section and a content section. The default implementation for the title section relies on a Gradient background. All title sections can have components embedded to the "left" or "right" of the Title.

Constructor Detail

BasicTitledPanelUI

public BasicTitledPanelUI()
Creates a new instance of BasicTitledPanelUI

Method Detail

createUI

public static ComponentUI createUI(JComponent c)
Returns an instance of the UI delegate for the specified component. Each subclass must provide its own static createUI 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(JComponent c)
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:
c - the component where this UI delegate is being installed

uninstallDefaults

protected void uninstallDefaults(JXTitledPanel titledPanel)

installComponents

getCaptionInsets

protected Insets getCaptionInsets()

createAndConfigureTopPanel

protected JXPanel createAndConfigureTopPanel(JXTitledPanel titledPanel)

createAndConfigureCaption

protected JLabel createAndConfigureCaption(JXTitledPanel titledPanel)

uninstallUI

public void uninstallUI(JComponent c)
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:
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

installUI(javax.swing.JComponent), JComponent.updateUI()

installListeners

protected void installListeners(JXTitledPanel titledPanel)

uninstallListeners

protected void uninstallListeners(JXTitledPanel titledPanel)

installProperty

protected void installProperty(JComponent c,
                               String propName,
                               Object value)

paint

public void paint(Graphics g,
                  JComponent c)
Paints the specified component appropriate for the look and feel. This method is invoked from the ComponentUI.update method when the specified component is being painted. Subclasses should override this method and use the specified Graphics object to render the content of the component.

PENDING JW: we don't need this, do we - remove!

Overrides:
paint 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
