* GtkDestDefaults:
|
|||
|
|
* @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.
|
|||
|
|
*
|
|||
|
|
* The #GtkDestDefaults enumeration specifies the various
|
|||
|
|
* types of action that will be taken on behalf
|
|||
|
|
* of the user for a drag destination site.
