the data_received() function isn't called because the data_get() function
doesn't provide any data.  add this line to faceWidget::on_drag_data_get()

gtk_selection_data_set(selection_data, selection_data->target, 8, NULL, 0);

the idea is to transport actual data this way, but your faceWidget class
is another faceWidget's friend after all.
