struct Gtk::DragSource::PrepareSignal
- Gtk::DragSource::PrepareSignal
- GObject::Signal
- Struct
- Value
- Object
Overview
Emitted when a drag is about to be initiated.
It returns the Gdk::ContentProvider to use for the drag that is about
to start. The default handler for this signal returns the value of
the Gtk::DragSource#content property, so if you set up that
property ahead of time, you don't need to connect to this signal.
