title: How do I get the ID of the X Window created by DirectFB?
body: <p>I'm developing for a program that uses DirectFB and GStreamer-0.10. I'm using <code>gst_x_overlay_set_xwindow_id()</code> from the <code>gstxoverlay</code> library of GStreamer to tell GStreamer to render to the window created by DirectFB. <code>gst_x_overlay_set_xwindow_id()</code> requires that I give it the ID of the X Window I want to render to, but I can't seem to find a way to get that from DirectFB.</p>
  
  <p>Is there any way to get the X Window ID of the window created by DirectFB? If there isn't any easy way, is there a way to do some hackery with DirectFB's source files to accomplish this?</p>
