Hi,
Should the virtual-root property found in GtkTreeModelFilter stay valid
all the time relative to parent model. I am having a problem that virtual-root
do not point a valid child node after nodes are added to child model in
a certain way. See the attached tester. Is this a bug or am I doing something
wrong?
I need this because I cannot just use gtk_tree_model_get for the root node
(NULL iterators/paths are not allowed).

#include <gtk/gtk.h>
int main(int argc, char *argv[])
{
GtkTreeModel *filter;
GtkTreeStore *store;
GtkTreeIter iter, child_iter;
GtkTreePath *path;
gboolean success;
gtk_init(&argc, &argv);
store = gtk_tree_store_new(1, G_TYPE_INT);
gtk_tree_store_append(store, &iter, NULL);
gtk_tree_store_set(store, &iter, 0, 0, -1);
gtk_tree_store_append(store, &iter, NULL);
gtk_tree_store_set(store, &iter, 0, 1, -1);
gtk_tree_store_append(store, &child_iter, &iter);
gtk_tree_store_set(store, &child_iter, 0, 3, -1);
path = gtk_tree_model_get_path(GTK_TREE_MODEL(store), &child_iter);
g_assert(path != NULL);
filter = gtk_tree_model_filter_new(GTK_TREE_MODEL(store), path);
gtk_tree_model_get_iter_first(GTK_TREE_MODEL(store), &iter);
/* Virtual root changes here */
gtk_tree_store_append(store, &child_iter, &iter);
g_object_get(filter, "virtual-root", &path, NULL);
/* We should get an iterator pointing to number 3, but
virtual root do not point to any node. */
success = gtk_tree_model_get_iter(GTK_TREE_MODEL(store), &iter, path);
g_assert(success); /* This fails */
return 0;
}
