Use the other version of layoutCompoundLabel() instead.
  - paintComponent
```
public static void paintComponent(Graphics g,
                  Component c,
                  Container p,
                  int x,
                  int y,
                  int w,
                  int h)
```
    Paints a component to the specified Graphics. This method is primarily useful to render Components that don't exist as part of the visible containment hierarchy, but are used for rendering. For example, if you are doing your own rendering and want to render some text (or even HTML), you could make use of JLabel's text rendering support and have it paint directly by way of this method, without adding the label to the visible containment hierarchy.
    This method makes use of CellRendererPane to handle the actual painting, and is only recommended if you use one component for rendering. If you make use of multiple components to handle the rendering, as JTable does, use CellRendererPane directly. Otherwise, as described below, you could end up with a CellRendererPane per Component.
    If c's parent is not a CellRendererPane, a new CellRendererPane is created, c is added to it, and the CellRendererPane is added to p. If c's parent is a CellRendererPane and the CellRendererPanes parent is not p, it is added to p.
    The component should either descend from JComponent or be another kind of lightweight component. A lightweight component is one whose "lightweight" property (returned by the Component isLightweight method) is true. If the Component is not lightweight, bad things map happen: crashes, exceptions, painting problems...
    
    Parameters:
    g - the Graphics object to draw on
    c - the Component to draw
    p - the intermediate Container
    x - an int specifying the left side of the area draw in, in pixels, measured from the left edge of the graphics context
    y - an int specifying the top of the area to draw in, in pixels measured down from the top edge of the graphics context
    w - an int specifying the width of the area draw in, in pixels
    h - an int specifying the height of the area draw in, in pixels
    See Also:
    CellRendererPane, Component.isLightweight()
  - paintComponent
```
public static void paintComponent(Graphics g,
                  Component c,
                  Container p,
                  Rectangle r)
```
    Paints a component to the specified Graphics. This is a cover method for paintComponent(Graphics,Component,Container,int,int,int,int). Refer to it for more information.
    
    Parameters:
    g - the Graphics object to draw on
    c - the Component to draw
    p - the intermediate Container
    r - the Rectangle to draw in
    See Also:
    paintComponent(Graphics,Component,Container,int,int,int,int), CellRendererPane
  - updateComponentTreeUI
```
public static void updateComponentTreeUI(Component c)
```
    A simple minded look and feel change: ask each node in the tree to updateUI() -- that is, to initialize its UI property with the current look and feel.
  - invokeLater
```
public static void invokeLater(Runnable doRun)
```
    Causes doRun.run() to be executed asynchronously on the AWT event dispatching thread. This will happen after all pending AWT events have been processed. This method should be used when an application thread needs to update the GUI. In the following example the invokeLater call queues the Runnable object doHelloWorld on the event dispatching thread and then prints a message.
```
 Runnable doHelloWorld = new Runnable() {
     public void run() {
         System.out.println("Hello World on " + Thread.currentThread());
     }
 };

 SwingUtilities.invokeLater(doHelloWorld);
 System.out.println("This might well be displayed before the other message.");
 
```
    If invokeLater is called from the event dispatching thread -- for example, from a JButton's ActionListener -- the doRun.run() will still be deferred until all pending events have been processed. Note that if the doRun.run() throws an uncaught exception the event dispatching thread will unwind (not the current thread).
    Additional documentation and examples for this method can be found in How to Use Threads, in The Java Tutorial.
    As of 1.3 this method is just a cover for java.awt.EventQueue.invokeLater().
    Unlike the rest of Swing, this method can be invoked from any thread.
    See Also:
    invokeAndWait(java.lang.Runnable)
  - invokeAndWait
```
public static void invokeAndWait(Runnable doRun)
                          throws InterruptedException,
                                 InvocationTargetException
```
    Causes doRun.run() to be executed synchronously on the AWT event dispatching thread. This call blocks until all pending AWT events have been processed and (then) doRun.run() returns. This method should be used when an application thread needs to update the GUI. It shouldn't be called from the event dispatching thread. Here's an example that creates a new application thread that uses invokeAndWait to print a string from the event dispatching thread and then, when that's finished, print a string from the application thread.
```
 final Runnable doHelloWorld = new Runnable() {
     public void run() {
         System.out.println("Hello World on " + Thread.currentThread());
     }
 };

 Thread appThread = new Thread() {
     public void run() {
         try {
             SwingUtilities.invokeAndWait(doHelloWorld);
         }
         catch (Exception e) {
             e.printStackTrace();
         }
         System.out.println("Finished on " + Thread.currentThread());
     }
 };
 appThread.start();
 
```
    Note that if the Runnable.run method throws an uncaught exception (on the event dispatching thread) it's caught and rethrown, as an InvocationTargetException, on the caller's thread.
    Additional documentation and examples for this method can be found in How to Use Threads, in The Java Tutorial.
    As of 1.3 this method is just a cover for java.awt.EventQueue.invokeAndWait().
    Throws:
    
    InterruptedException - if we're interrupted while waiting for the event dispatching thread to finish excecuting doRun.run()
    
    InvocationTargetException - if an exception is thrown while running doRun
    See Also:
    invokeLater(java.lang.Runnable)
  - isEventDispatchThread
```
public static boolean isEventDispatchThread()
```
    Returns true if the current thread is an AWT event dispatching thread.
    As of 1.3 this method is just a cover for java.awt.EventQueue.isDispatchThread().
    
    Returns:
    true if the current thread is an AWT event dispatching thread
  - getAccessibleIndexInParent
```
public static int getAccessibleIndexInParent(Component c)
```
    Get the index of this object in its accessible parent.
    Note: as of the Java 2 platform v1.3, it is recommended that developers call Component.AccessibleAWTComponent.getAccessibleIndexInParent() instead of using this method.

    AccessibleState
  - getAccessibleChildrenCount
```
public static int getAccessibleChildrenCount(Component c)
```
    Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.
    Note: as of the Java 2 platform v1.3, it is recommended that developers call Component.AccessibleAWTComponent.getAccessibleIndexInParent() instead of using this method.
    
    Returns:
    the number of accessible children in the object.
  - getAccessibleChild
```
public static Accessible getAccessibleChild(Component c,
                            int i)
```
    Return the nth Accessible child of the object.
    Note: as of the Java 2 platform v1.3, it is recommended that developers call Component.AccessibleAWTComponent.getAccessibleIndexInParent() instead of using this method.
    
    Parameters:
    i - zero-based index of child
    
    Returns:
    the nth Accessible child of the object
  - findFocusOwner
```
@Deprecated
public static Component findFocusOwner(Component c)
```
    Deprecated. As of 1.4, replaced by KeyboardFocusManager.getFocusOwner().
    
    Return the child Component of the specified Component that is the focus owner, if any.
    
    Parameters:
    c - the root of the Component hierarchy to search for the focus owner
    
    Returns:
    the focus owner, or null if there is no focus owner, or if the focus owner is not comp, or a descendant of comp
    See Also:
    KeyboardFocusManager.getFocusOwner()
  - getRootPane
```
public static JRootPane getRootPane(Component c)
```
    If c is a JRootPane descendant return its JRootPane ancestor. If c is a RootPaneContainer then return its JRootPane.
    
    Returns:
    the JRootPane for Component c or null.
  - getRoot
```
public static Component getRoot(Component c)
```
    Returns the root component for the current component tree.
    
    Returns:
    the first ancestor of c that's a Window or the last Applet ancestor
  - processKeyBindings
```
public static boolean processKeyBindings(KeyEvent event)
```
    Process the key bindings for the Component associated with event. This method is only useful if event.getComponent() does not descend from JComponent, or your are not invoking super.processKeyEvent from within your JComponent subclass. JComponent automatically processes bindings from within its processKeyEvent method, hence you rarely need to directly invoke this method.
    
    Parameters:
    event - KeyEvent used to identify which bindings to process, as well as which Component has focus.
    
    Returns:
    true if a binding has found and processed
    Since:
    
    1.4
  - notifyAction
```
public static boolean notifyAction(Action action,
                   KeyStroke ks,
                   KeyEvent event,
                   Object sender,
                   int modifiers)
```
    Invokes actionPerformed on action if action is enabled (and non-null). The command for the ActionEvent is determined by:
    1. If the action was registered via registerKeyboardAction, then the command string passed in (null will be used if null was passed in).
    2. Action value with name Action.ACTION_COMMAND_KEY, unless null.
    3. String value of the KeyEvent, unless getKeyChar returns KeyEvent.CHAR_UNDEFINED..
    This will return true if action is non-null and actionPerformed is invoked on it.
    Since:
    
    1.3
  - replaceUIInputMap
```
public static void replaceUIInputMap(JComponent component,
                     int type,
                     InputMap uiInputMap)
```
    Convenience method to change the UI InputMap for component to uiInputMap. If uiInputMap is null, this removes any previously installed UI InputMap.
    
    Since:
    
    1.3
  - replaceUIActionMap
```
public static void replaceUIActionMap(JComponent component,
                      ActionMap uiActionMap)
```
    Convenience method to change the UI ActionMap for component to uiActionMap. If uiActionMap is null, this removes any previously installed UI ActionMap.
    
    Since:
    
    1.3
  - getUIInputMap
```
public static InputMap getUIInputMap(JComponent component,
                     int condition)
```
    Returns the InputMap provided by the UI for condition condition in component component.
    This will return null if the UI has not installed a InputMap of the specified type.
    
    Since:
    
    1.3
  - getUIActionMap
```
public static ActionMap getUIActionMap(JComponent component)
```
    Returns the ActionMap provided by the UI in component component.
    This will return null if the UI has not installed an ActionMap.
    
    Since:
    
    1.3
  - calculateInnerArea
```
public static Rectangle calculateInnerArea(JComponent c,
                           Rectangle r)
```
    Stores the position and size of the inner painting area of the specified component in r and returns r. The position and size specify the bounds of the component, adjusted so as not to include the border area (the insets). This method is useful for classes that implement painting code.
    
    Parameters:
    c - the JComponent in question; if null, this method returns null
    r - the Rectangle instance to be modified; may be null
    
    Returns:
    null if the Component is null; otherwise, returns the passed-in rectangle (if non-null) or a new rectangle specifying position and size information
    Since:
    
    1.4
  - getUnwrappedParent
```
public static Container getUnwrappedParent(Component component)
```
    Returns the first ancestor of the component which is not an instance of JLayer.
    
    Parameters:
    component - Component to get the first ancestor of, which is not a JLayer instance.
    
    Returns:
    the first ancestor of the component which is not an instance of JLayer. If such an ancestor can not be found, null is returned.
    
    Throws:
    
    NullPointerException - if component is null
    Since:
    
    1.7

    JLayer
  - getUnwrappedView
```
public static Component getUnwrappedView(JViewport viewport)
```
    Returns the first JViewport's descendant which is not an instance of JLayer. If such a descendant can not be found, null is returned. If the viewport's view component is not a JLayer, this method is equivalent to JViewport.getView() otherwise JLayer.getView() will be recursively called on all descending JLayers.
    
    Parameters:
    viewport - JViewport to get the first descendant of, which in not a JLayer instance.
    
    Returns:
    the first JViewport's descendant which is not an instance of JLayer. If such a descendant can not be found, null is returned.
    
    Throws:
    
    NullPointerException - if viewport is null
    Since:
    
    1.7
