Re: drawing in a for-loop

OK, this is probably the stupidest post ever, but I need help drawing in a for-loop within a callback function... I've done this before, but for some reason, I'm not getting expose events to refresh my GtkDrawingArea... My code looks like this (using gtkmm, but doesn't matter)...

void mainWindow::button_callback()
  //GtkDrawingArea is called '* area'
  width = GTK_WIDGET(area)->allocation.width;
  height = " " ".height;

  for (int i=0; i<200; i++)
    gtk_widget_queue_draw_area((GtkWidget *) area,0,0,width,height);
      while (gtk_events_pending ())
        gtk_main_iteration ();
