setContent

Sets a content provider on a GtkDragSource.

When the data is requested in the cause of a DND operation, it will be obtained from the content provider.

This function can be called before a drag is started, or in a handler for the signal@Gtk.DragSource::prepare signal.

You may consider setting the content provider back to null in a signal@Gtk.DragSource::drag-end signal handler.
