             * (#GtkWidget::drag-motion, #GtkWidget::drag-drop, ...). They all exist

             * (#GtkWidget::drag-motion, #GtkWidget::drag-drop, ...). They all exist

             * handler calls gtk_drag_get_data() to inspect the dragged data.
             *
             * There’s no way to set a default action here, you can use the
