Orígenes y destinos

Things are dragged from sources to be dropped on destinations. Each source and destination has information about the data formats that it can send or receive, provided by Gdk::ContentFormats. A drop destination will only accept a dragged item if they both share a compatible format. Appropriate signals will then be emitted, telling the signal handlers which format was used.

Gdk::ContentFormats objects contain information about available GTypes and mime types (media types).
