In your main() ore more precisely before fl_do_forms, try:
fl_register_raw_callback(fd_my_frm->my_frm, KeyPressMask, xevhandler);
and create the appropriate XEvent handler function:
int xevhandler(FL_FORM *form, void *xev)
{
XKeyEvent *xkey;
XButtonEvent *xbutton;
int keysym;
switch ( ((XKeyEvent *)xev)->type ) {
case KeyPress:
xkey = (XKeyEvent *)xev;
keysym = XKeycodeToKeysym(xkey->display, xkey->keycode, 0);
switch ( keysym ) {
case XK_KP_Enter:
/* do keypad enter key stuff */
break;
case XK_Return:
/* do 'big' return key stuff */
...
/* After customizing return key behaviour, this */
/* key shall be handled by the default handler */
/* as well, thus (!FL_PREEMPT) */
return(!FL_PREEMPT);
...
case XK_Meta_L:
case XK_Meta_R:
case XK_Alt_L:
/* These keys are marked as already handled by */
/* this function, thus (FL_PREEMPT) */
return(FL_PREEMPT);
...
} /* keysym */
case ButtonPress:
xbutton = (XButtonEvent*)xev;
switch ( xbutton->button ) {
case 1: /* Left mouse button */
...
break;
case 2: /* middle mouse button */
...
} /* switch xev-type */
} /* xevhandler */
