Re: How to restrict mouse pointer movement within a certain area using DirectFB?

Here is the implelemtation .. add it to gdk/directfb/gdkwindow-directfb.c

Hope this works for you

void
gdk_display_warp_pointer (GdkDisplay *display,
			  GdkScreen  *screen,
			  gint        x,
			  gint        y)
{

  GdkWindowObject       *private;
  GdkWindowImplDirectFB *impl;
  DFBWindowEvent         evt; 

  GdkWindow *window = gdk_screen_get_root_window (screen);
  private = GDK_WINDOW_OBJECT (window);
  impl = GDK_WINDOW_IMPL_DIRECTFB (private->impl);

  if (x >= 0 && y >= 0) {
    int win_x, win_y;
    impl->window->GetPosition (impl->window, &win_x, &win_y);
    if (_gdk_display->layer->WarpCursor (_gdk_display->layer, win_x+x,
win_y+y))
      return ;
  }
}
