See the "Keyboard Events" section of the "Handling Events" chapter:
http://fltk.org/doc-1.3/events.html#events_fl_keydown
Specifically:
"To receive FL_KEYBOARD events you must also respond to the
FL_FOCUS and FL_UNFOCUS events.."
..which means returning a '1' when your widget receives
FL_FOCUS/UNFOCUS events.
This is all in the name of efficiency; FLTK won't waste time
sending keyboard events to your widget if it doesn't express
an interest in them. It only does so on the 'second pass' when
no other widget expressed an interest in them either, so FLTK
takes another shot at the widgets sending it as a 'shortcut',
so that shortcuts don't eclipse eg. Fl_Input widgets.
Or something like that, I imagine..
I'd suggest writing your handle() method this way:
int handle(int e) {
int ret = Fl_Gl_Window::handle(e);
printf("EVENT=%d\n",e);
switch ( e ) {
..events you're interested in..
case FL_FOCUS:
case FL_UNFOCUS:
ret = 1; // express interest..
break;
case FL_KEYBOARD:
..handle buttons..
ret = 1;
break;
}
return(e);
}
HTH.
