Hi! I'm still struggling with GtkTreeView & co. I'm going to explain my problem and then perhaps someone may drop a hint... I need a GtkListStore of six columns: 1 ... a string (filter name) 2 ... a checkbox (should data be plotted) 3 ... a checkbox (should lines be drawn) 4 ... a pixbuf (choose the data color) 5 ... a pixbuf (choose the line color) 6 ... a double (vertical offset) These columns should be editable - the user should be able to change them directly within GtkTreeView. So far I have tried to create only the first two columns to get at least the toggle button working. I tried it like this: plot_lc_data_info_list_store = gtk_list_store_new (2, G_TYPE_STRING, G_TYPE_BOOLEAN); plot_lc_data_info_list_table = gtk_tree_view_new_with_model (GTK_TREE_MODEL (plot_lc_data_info_list_store)); plot_lc_data_info_list_renderer_text = gtk_cell_renderer_text_new (); plot_lc_data_info_list_renderer_toggle = gtk_cell_renderer_toggle_new (); plot_lc_data_info_list_column_1 = gtk_tree_view_column_new (); gtk_tree_view_column_set_alignment (plot_lc_data_info_list_column_1, 0.5); gtk_tree_view_column_set_title (plot_lc_data_info_list_column_1, "Filter"); gtk_tree_view_column_pack_start (plot_lc_data_info_list_column_1, plot_lc_data_info_list_renderer_text, FALSE); gtk_tree_view_column_add_attribute (plot_lc_data_info_list_column_1, plot_lc_data_info_list_renderer_text, "text", 0); gtk_tree_view_column_set_resizable (plot_lc_data_info_list_column_1, TRUE); gtk_tree_view_append_column (GTK_TREE_VIEW (plot_lc_data_info_list_table), plot_lc_data_info_list_column_1); plot_lc_data_info_list_column_2 = gtk_tree_view_column_new (); g_object_set_data (G_OBJECT (PHOEBE), "plot_lc_data_info_list_column_2", plot_lc_data_info_list_column_2); gtk_tree_view_column_set_alignment (plot_lc_data_info_list_column_2, 0.5); gtk_tree_view_column_set_title (plot_lc_data_info_list_column_2, "Plot experimental?"); gtk_tree_view_column_pack_start (plot_lc_data_info_list_column_2, plot_lc_data_info_list_renderer_toggle, FALSE); gtk_tree_view_column_add_attribute (plot_lc_data_info_list_column_2, plot_lc_data_info_list_renderer_toggle, "activatable", 1); gtk_tree_view_column_set_resizable (plot_lc_data_info_list_column_2, TRUE); gtk_tree_view_append_column (GTK_TREE_VIEW (plot_lc_data_info_list_table), plot_lc_data_info_list_column_2); gtk_list_store_append (plot_lc_data_info_list_store, &iter); gtk_list_store_set (plot_lc_data_info_list_store, &iter, 0, "Filter name", -1); gtk_list_store_set (plot_lc_data_info_list_store, &iter, 1, TRUE, -1); (I apologize for WAY too long lines above). This works in showing the rows properly, but I don't have a clue on how to make a checkbox editable. Help? Thanks, Andrej
