The GtkDestDefaults enumeration specifies the various
types of action that will be taken on behalf
of the user for a drag destination site.
GTK_DEST_DEFAULT_MOTION
If set for a widget, GTK+, during a drag over this
widget will check if the drag matches this widget's list of possible targets
and actions.
GTK+ will then call gdk_drag_status() as appropriate.
GTK_DEST_DEFAULT_HIGHLIGHT
If set for a widget, GTK+ will draw a highlight on
this widget as long as a drag is over this widget and the widget drag format
and action are acceptable.
GTK_DEST_DEFAULT_DROP
If set for a widget, when a drop occurs, GTK+ will
will check if the drag matches this widget's list of possible targets and
actions. If so, GTK+ will call gtk_drag_get_data() on behalf of the widget.
Whether or not the drop is successful, GTK+ will call gtk_drag_finish(). If
the action was a move, then if the drag was successful, then TRUE will be
passed for the delete parameter to gtk_drag_finish().
GTK_DEST_DEFAULT_ALL
If set, specifies that all default actions should
be taken.
