I assume this is on windows? (I don't think Alt+F4 is a close command on other platforms, at least not on this Mac...) Anyway, I'm pretty certain that key-combination is handled by the win32 window manager, so it is very likely that the key presses never really find their way to you app. I think maybe what you want to try (I don't know if it will work) is to override the window close callback as described in this note: http://www.fltk.org/articles.php?L378+I0+T+M10+P1+Qescape That might work for your case too. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
