[maemo-developers] [maemo-developers] gtk, gstreamer movie window = problem

[From: cmonst]

Hi!
I tried to solve this problem but still the same happens. I'm running
program from xterm so I think I don't need osso_initialize(), and on
console I don't get any error messages. This is code I'm using (I'm
out of ideas what can be wrong):

//main gui function
gui(){
	HildonProgram *app;

	/* Create the hildon application and setup the title */
	app = HILDON_PROGRAM (hildon_program_get_instance ());
	g_set_application_name ("Menu Example App");

	/* Create HildonAppView and set it to HildonApp */
	appview = HILDON_WINDOW (hildon_window_new ());

	hildon_program_add_window (app, appview);


	/* Create menu for view */
	create_menu (appview);


	///box1 = gtk_hbox_new (FALSE, 0);



	///box2 = gtk_vbox_new (homogeneous, spacing);
	///label = gtk_label_new ("Volume:");
	///gtk_misc_set_alignment (GTK_MISC (label), 0, 0);
	///gtk_box_pack_start (GTK_BOX (box2), label, FALSE, FALSE, 0);

	///gtk_widget_show (label);

	///adj1 = gtk_adjustment_new (1.0, 0.0, 4.0, 0.1, 1.0, 1.0);
	///g_signal_connect (G_OBJECT (adj1), "value_changed",G_CALLBACK
(cb_digits_scale), NULL);
	///scale = gtk_vscrollbar_new (GTK_ADJUSTMENT (adj1));
	///gtk_box_pack_start (GTK_BOX (box2), scale, TRUE, TRUE, 0);



	///gtk_box_pack_start (GTK_BOX (box1), box2, expand, fill, padding);


	content = gtk_event_box_new ();
	gtk_container_add (GTK_CONTAINER (appview), content);

	GstBus *bus;
	bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline));
  	gst_bus_set_sync_handler (bus, (GstBusSyncHandler) create_window, NULL);
	gst_object_unref (bus);


	g_signal_connect (content, "expose-event", G_CALLBACK (cb_expose), videosink);


	//gtk_box_pack_start (GTK_BOX (box1), content, TRUE, TRUE, padding);


	///gtk_container_add (GTK_CONTAINER (appview), box1);
	///gtk_widget_show (box1);


	gtk_widget_show_all (appview);
	
	g_signal_connect(G_OBJECT(appview), "delete_event",
      G_CALLBACK(item_close_cb), NULL);

}

//callback functins
static GstBusSyncReply
create_window (GstBus * bus, GstMessage * message, GstPipeline * pipeline)
{
	XGCValues values;

	if (GST_MESSAGE_TYPE (message) != GST_MESSAGE_ELEMENT)
   return GST_BUS_PASS;

  if (!gst_structure_has_name (message->structure, "prepare-xwindow-id"))
   return GST_BUS_PASS;

	// ignore anything but 'prepare-xwindow-id' element messages

	content = gtk_event_box_new ();
	gst_x_overlay_set_xwindow_id (GST_X_OVERLAY
				      (GST_MESSAGE_SRC (message)), content->window);



	return GST_BUS_DROP;
}


cb_expose (GtkWidget * w, GdkEventExpose * ev, GstElement * e)
{
	if (GST_IS_X_OVERLAY (e) &&
	    !GTK_WIDGET_NO_WINDOW (w) && GTK_WIDGET_REALIZED (w))
	{
		gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (e),
					      GDK_WINDOW_XWINDOW (w->window));

	}
}
