You can place a invisible widget e.g. Fl_Box with the attribute 
Fl_No_Box over the whole application, which just recieves D&D events 
like in your described even handler and filters only these. All other 
events from mouse, keyboard etc. should pass to get handled as usual by 
the appropriate widgets.
