hi Dan,
For moving a window without decoration,you can use a eventbox to catch the
event for dragging.Add a callback fn(Suppose on_drag) to that event box for
button_press_event,button_release_event,motion_notify_event.In the callback
u can use following code.

gint start_x,start_y;(global)
GtkWidget* window;

gboolean on_drag(GtkWidget	     *widget,
					 GdkEventButton      *event)
{

	static GdkEventType previous_type = GDK_NOTHING;
	gint now_x,now_y;



	if(event->type == GDK_BUTTON_PRESS)//for getting the start point
	{
		start_x = (gint)event->x;
		start_y = (gint)event->y;
		previous_type = event->type;
	}


	//move TopLevelWindow to new position
	if((event->type == GDK_MOTION_NOTIFY) &&(previous_type ==
GDK_BUTTON_PRESS))
	{

		//getting the current window position
		gtk_window_get_position(
			GTK_WINDOW(window),&now_x,&now_y);

		//moving the window
		gtk_window_move(GTK_WINDOW(window),
			(now_x+(gint)event->x - start_x),(now_y +(gint)event->y - start_y));
	}

	return TRUE;

}

i hope it will work.
