Greetings, I have a GtkTreeView/Store which represents a tree which is basically like a directory tree, but only leaf "directories" may contain "files". I would like to implement an ability to move any "directory" (with all its contents, i.e. the entire subtree) to any other "directory", possibly on other level in the tree, by means of drag and drop and possibly other mechanisms.
gtk_tree_store_move_before() and gtk_tree_store_move_after() say that "iter and position should be in the same level". _Should_ be? Why? _Can_ they be on different levels (maybe in some specific situations)? gtk_tree_store_swap() seems to have the same problem (although no "should" in this case). Are there other ways (that I haven't been able to find) that I could conveniently move rows and their children around? Are there improved TreeModel implementations (not part of Gtk+ distribution) that I could use? I suppose I could copy the entire subtree to the target location and then remove the source, but how, in this case, would I ensure that GtkTreeRowReferences that point to the moved directory or its children point to the new location after the operation? It seems to me that the signals RowReferences use to track model changes do not make it possible (at least not sanely) to handle cases where the row the RowReference points to is first deleted and then inserted elsewhere. -- Hannu _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
