Sure.

object win; object da; array dasize;

void show_current() { return; }

int main(int ac,array am) { GTK2.setup_gtk(am);

win=GTK2.Window(GTK2.WindowToplevel); win->set_size_request(700,1000);

object hbox=GTK2.Hpaned();

da=GTK2.DrawingArea();

da->signal_connect("configure-event",lambda(object da,array req) { dasize=({ req[0]->width, req[0]->height}); remove_call_out(show_current); call_out(show_current,0); });

hbox->add(da);

win->add(hbox); win->show_all();

show_current();

return -1; }
