hello all, can anyone tell me the list of methods to override in order to create a custom TreeModel?
I currently have these: virtual Gtk::TreeModelFlags get_flags_vfunc() const; virtual int get_n_columns_vfunc() const; virtual GType get_column_type_vfunc(int index) const; virtual void get_value_vfunc(const TreeModel::iterator& iter, int column, Glib::ValueBase& value) const; bool iter_next_vfunc(const iterator& iter, iterator& iter_next) const; virtual bool iter_children_vfunc(const iterator& parent, iterator& iter) const; virtual bool iter_has_child_vfunc(const iterator& iter) const; virtual int iter_n_children_vfunc(const iterator& iter) const; virtual int iter_n_root_children_vfunc() const; virtual bool iter_nth_child_vfunc(const iterator& parent, int n, iterator& iter) const; virtual bool iter_nth_root_child_vfunc(int n, iterator& iter) const; virtual bool iter_parent_vfunc(const iterator& child, iterator& iter) const; virtual Path get_path_vfunc(const iterator& iter) const; virtual bool get_iter_vfunc(const Path& path, iterator& iter) const; but I keep getting this when I try to set the model in the treeview: (gtkmm-demo:6627): GLib-GObject-WARNING **: attempting to add an interface (GtkTreeModel) to class (gtkmm__CustomObject_16Memory_TreeModel) after class_init (gtkmm-demo:6627): Gtk-CRITICAL **: gtk_tree_view_set_model: assertion 'model == NULL || GTK_IS_TREE_MODEL (model)' failed regards, danny.
