## Chapter 15. Drag and Drop

Gtk::Widget has several methods and signals which are prefixed with "drag_". These are used for Drag and Drop.

## Sources and Destinations

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: TODO
