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