In a GtkTree I want to use a filter, and also extend the tree using gtk_tree_model_foreach. The combination of the 2 gives problems. In the function connected to gtk_tree_model_foreach I use the GtkTreeIter *iter argument, which gives an error message:
Gtk-CRITICAL **: IA__gtk_tree_store_append: assertion `VALID_ITER (parent, tree_store)' failed I define tree, filter etc. as follows: stree = gtk_tree_store_new(1,G_TYPE_STRING); ftree = GTK_TREE_MODEL_FILTER(gtk_tree_model_filter_new(GTK_TREE_MODEL(stree), NULL)); tree = gtk_tree_view_new_with_model(GTK_TREE_MODEL(ftree)); model=gtk_tree_view_get_model(GTK_TREE_VIEW(tree)); ... (build a part of the tree) ... gtk_tree_model_foreach(model,func,NULL); In func: gboolean func(GtkTreeModel *model,GtkTreePath *path,GtkTreeIter *iter,gpointer data) { gtk_tree_model_get(model,iter, 0, &iname, -1); ... gtk_tree_store_append(stree, &iter0, iter); ... } gtk_tree_store_append gives the mentioned error. If I remove the filter, and define instead: tree = gtk_tree_view_new_with_model(GTK_TREE_MODEL(stree)); then building using gtk_tree_model_foreach works fine. How to solve this? Attached an example showing the problem. (Note: I am using gtk2.0, don't know if the same problem is with gtk3.) _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
