Now I am creating a new program and want to create a Treeview with a parent iter and 6 set child iter (ie you create a "new row" and the row auto creates the 6 children underneath) But I am having trouble doing ANYTHING with the treeview. Cut/paste the example from the gtk 2.0 API simply fails to do anything. I am left with a blank screen. inserting g_print shows that the code is being called, but nothing is being displayed. Since the gtk_tree_view is created in glade, I am simply doing a lookup_widget on the treeview and adding columns to it (ie none exist) and then populating the data. My code, very stripped down (to remove possible errors) is: void on_harpmanager_show (GtkWidget *widget, gpointer user_data) { GtkTreeStore *tree_store; GtkTreeIter parent_iter, child_iter; GtkWidget *view; GtkCellRenderer *renderer; GtkTreeSelection *selection; GtkTreeViewColumn *col; // CREATE THE TREE_VIEW and hook the row selection event into it! view = lookup_widget(widget, "treeview_base"); selection = gtk_tree_view_get_selection(GTK_TREE_VIEW(view)); gtk_tree_selection_set_select_function(selection, func_base_select, NULL, NULL); // CREATE COLUMN HEADERS if (gtk_tree_view_get_column(GTK_TREE_VIEW(view), 0) == NULL) { // -- Column 1 -- col = gtk_tree_view_column_new(); gtk_tree_view_column_set_title(col, "CHARACTER NAME"); gtk_tree_view_append_column(GTK_TREE_VIEW(view), col); renderer = gtk_cell_renderer_text_new(); gtk_tree_view_column_pack_start(col, renderer, TRUE); gtk_tree_view_column_add_attribute(col, renderer, "text", 0); } } With this I should get a simple treeview with column headings, but I get nothing. Adding the following also produces a blank screen. tree_store = gtk_tree_store_new (1, G_TYPE_STRING); gtk_tree_store_append (tree_store, &parent_iter, NULL); gtk_tree_store_set (tree_store, &parent_iter, 0, "Darkeen", -1); gtk_tree_store_append (tree_store, &parent_iter, &child_iter); gtk_tree_store_set (tree_store, &child_iter, 0, "Profession", -1); gtk_tree_store_append (tree_store, &parent_iter, &child_iter); gtk_tree_store_set (tree_store, &child_iter, 0, "Race", -1); gtk_tree_store_append (tree_store, &parent_iter, &child_iter); gtk_tree_store_set (tree_store, &child_iter, 0, "Talents", -1); gtk_tree_store_append (tree_store, &parent_iter, &child_iter); gtk_tree_store_set (tree_store, &child_iter, 0, "Skills", -1); gtk_tree_store_append (tree_store, &parent_iter, &child_iter); gtk_tree_store_set (tree_store, &child_iter, 0, "Equipment", -1); gtk_tree_view_set_model (GTK_TREE_VIEW(view), GTK_TREE_MODEL(tree_store)); g_object_unref (tree_store); gtk_widget_show_all(widget); HELP! -- --- Regards, Jason Brisbane _______________________________________________ Glade-users maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/glade-users _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
