A DESCRIPTION OF THE REQUEST :
Please add this class

package javax.swing;
public interface SourcesActionEvents {
    public void addActionListener(ActionListener l);
    public void removeActionListener(ActionListener l);
}

Then have all widgets with addActionListener implement this new interface. The Google Web Toolkit did this, and it now allows awesome programming of unit tests using mocklibraries. Check out the gwtMockLib for an example here......

http://mocklib.sourceforge.net

Please do this for all Swing events as well. Otherwise, I end up with a ListenerManager(see GwtMockLib example) that has multiple addActionListener methods that take different Swing components. This would be great for test first GUI development!!!!!

JUSTIFICATION :
Make unit testing and would allow the test to simulate events. See the GwtMockLib example at http://mocklib.sourceforge.net.
