Sat Nov 18 18:00:17 2000 Jonathan Blandford <jrb@redhat.com> * demos/gtk-demo/main.c: Changed to have the list become non-italic when the demo window is destroyed through an external event (like a close button). Doing so found three bugs in the widget. * demos/gtk-demo/*.c (do_*): Changed to return the toplevel window. * gtk/gtkliststore.c (gtk_list_store_set_cell): emit "change" when we actually set the cell. * gtk/gtktreestore.c (gtk_tree_store_set_cell): ditto * gtk/gtktreeselection.c (gtk_tree_selection_real_select_node): free a leaked path. Thanks memprof.
