struct Gtk::DragSource::PrepareSignal

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.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/drag_source.cr
