a timestamp for retrieving the data. This will generally be the time received in a "drag_data_motion" or "drag_data_drop" signal.
Gets the data associated with a drag. When the data is received or the retrieval fails, GTK+ will emit a "drag_data_received" signal. Failure of the retrieval is indicated by the length field of the selection_data signal parameter being negative. However, when gtk_drag_get_data() is called implicitely because the GTK_DEST_DEFAULT_DROP was set, then the widget will not receive notification of failed drops.
