The drag and drop signals provide a DragContext, which contains some information about the drag and drop operation and can be used to influence the process. For instance, you can discover the source widget, or change the drag and drop icon, by using the <tt class="literal">set_icon()</tt> methods. More importantly, you should call the <tt class="literal">drag_finish()</tt> method from your <tt class="literal">drag_data_received</tt> signal handler to indicate whether the drop was successful.
