Origens e destinos
Things are dragged from sources to be dropped on destinations. Each source and destination has infomation about the data formats that it can send or receive, provided by Gtk::TargetEntry items. A drop destination will only accept a dragged item if they both share a compatible Gtk::TargetEntry item. Appropriate signals will then be emitted, telling the signal handlers which Gtk::TargetEntry was used.
Gtk::TargetEntry objects contain this information:
- target: A name, such as "STRING"
- info: An identifier which will be sent to your signals to tell you which TargetEntry was used.
- flags: Used only for drag and drop, this specifies whether the data may be dragged to other widgets and applications, or only to the same ones.
