Size of popup menu

Is it possible to get the size of a popup menu in AWT.

I have a panel that contains an image. It appears that when the pop up
menu is closed the unerlying panel is painted. This causes flashing.
If I know the size of the popup menu I could just refresh the
underlying area of the popup menu when the paint is called.

Regards
Arthur

Examine the clipping region of the Graphics context you get in your
image paint[Component]() method. It should be set so you can determine
which parts need repainting.
