* only needs to be used when the application is

+ * The @event is used to retrieve the timestamp that will be used internally to
+ * grab the pointer. If @event is #NULL, then GDK_CURRENT_TIME will be used.
+ * However, you should try to pass a real event in all cases, since that can be
+ * used by GTK+ to get information about the start position of the drag, for
+ * example if the @event is a GDK_MOTION_NOTIFY.
+ *
+ * Generally there are three cases when you want to start a drag by hand by calling
+ * this function:
+ *
+ * 1. During a button-press-event handler, if you want to start a drag immediately
+ * when the user presses the mouse button. Pass the @event that you have in your
+ * button-press-event handler.
+ *
+ * 2. During a motion-notify-event handler, if you want to start a drag when the mouse
+ * moves past a certain threshold distance after a button-press. Pass the @event that you
+ * have in your motion-notify-event handler.
+ *
+ * 3. During a timeout handler, if you want to start a drag after the mouse
+ * button is held down for some time. Try to save the last event that you got
+ * from the mouse, using gdk_event_copy(), and pass it to this function
+ * (remember to free the event with gdk_event_free() when you are done). If you
+ * can really not pass a real event, pass #NULL instead.
*
* Return value: the context for this drag.
