set_content

Description:

public void set_content (ContentProvider? content)

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:GtkDragSource:prepare] signal.

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