Most of the time if you indicate that some class implements an interface you can 
choose "Synchronize" from the "Tools" menu to automatically generate those 
methods that you have not yet written code for.

When creating an anonymous inner class this option is unavailable.  For example:


        myPanel.addMouseListener(new MouseListener() {
            |
        });

If I open the Tools menu at this point, Synchronize is not one of the menu
options.
