+ * @Short_description: Functions for controlling drag and drop handling
+ * @Title: Drag and Drop
+ *
+ * GTK+ has a rich set of functions for doing inter-process
+ * communication via the drag-and-drop metaphor. GTK+
+ * can do drag-and-drop (DND) via multiple protocols.
+ * The currently supported protocols are the Xdnd and
+ * Motif protocols.
+ *
+ * As well as the functions listed here, applications
+ * may need to use some facilities provided for
+ * <link linkend="gtk-Selections">Selections</link>.
+ * Also, the Drag and Drop API makes use of signals
+ * in the #GtkWidget class.

+ *
+ * The @event is used to retrieve the timestamp that will be used internally to

+ * However, you should try to pass a real event in all cases, since that can be

+ * example if the @event is a %GDK_MOTION_NOTIFY.
+ *
+ * Generally there are three cases when you want to start a drag by hand by

+ *
+ * 1. During a #GtkWidget::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 #GtkWidget::button-press-event handler.
+ *
+ * 2. During a #GtkWidget::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 #GtkWidget::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.
