This function is a convenience function to allow you to reorder models that
GtkTreeDragSourceIface and the
GtkListStore support these. If
the user can reorder the model by dragging and dropping rows. The
developer can listen to these changes by connecting to the model’s
row_inserted and row_deleted signals. The reordering is implemented by setting up
the icon view as a drag source and destination. Therefore, drag and
drop can not be used in a reorderable view for any other purpose.
This function does not give you any degree of control over the order — any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.
