I see no warning with that test case, but I am only dragging rows inside the treeview itself. However, it's very possible that egg_tree_multi_drag_add_drag_support (treeview), which you call, expects the treeview to contain a model that implements the EggTreeMultiDragSource model. You'd need to find a model that does. -- Murray Cumming murrayc@xxxxxxxxxxx www.murrayc.com www.openismus.com _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
