Re: Error when executing my app

["Donna S. Martin" <donna omartin com>]

The prototype for a delete_event handler is
gboolean function( GtkWidget *, GdkEvent *, gpointer user_data);

gtk_main_quit() doesn't match this since it is
a parameterless function.  You might try adding a handler such as
this:

gboolean quit_handler( GtkWidget *, GdkEvent *, gpointer user_data)
{
    gtk_main_quit();
    return (FALSE);
}

The return is whether you are preventing the user from quitting - gives
you a chance to clean-up, ask if sure they want to quit, etc.  return
of FALSE allows them to quit.

Then attach the quit_handler through your delete_event......

HTH,
Donna
P.S. Of course there's also the destroy event to think about :-).
I would actually have the delete-event do a return FALSE
(and whatever else it needed) and allow the destroy event to do the
quit......
That way I can also use the destroy handler for any quit buttons or
menu items.   Personal preference I guess....
