    You could use XSendEvent() to send your events, as per the following

                fl_add_event_callback( window, KeyPress, handler, fd_form );

            int handler( XEvent *xev, void *data )
                FD_form *fd_form = ( FD_form *) data;
                XKeyPressedEvent *xkpe = ( XKeyPressedEvent *) xev;
                xkpe->send_event = True;
                xkpe->window = FL_ObjWin( fd_form->input );
                fl_set_focus_object( fd_form->form, fd_form->input );
                XSendEvent( fl_get_display(),
                            FL_ObjWin( fd_form->input ),
                            xev );
