Re: Question on DnD

[Jedy Wang <Jedy Wang Sun COM>]

From
http://library.gnome.org/devel/gdk/stable/gdk-Drag-and-Drop.html#GdkDragAction
------------------------------------------------------------------------
GdkDragAction actions; a bitmask of actions proposed by the source when
suggested_action is GDK_ACTION_ASK.
------------------------------------------------------------------------
It seems GdkDragContext->action only works when
GdkDragContext->suggested_action is GDK_ACTION_ASK.

Regardes,
