The usual way to do this is to place a transparent window (InputOnly,  
often called an "event window") over the place where you want to  
intercept clicks and select for ButtonPress on it.  Selecting for  
ButtonPress on the whole window (a) requires you to calculate whether  
to pay attention to it or not (b) complicates things when the  
application owning the window is *also* selecting for ButtonPress in  
the same area.
