Tue Dec 12 23:46:44 2000 Tim Janik <timj@gtk.org> * gtk/stock-icons/Makefile.am: doh, this was broken beyond believe. * gtk/gtkbox.c: change property types from (u)long to (u)int for ::position and ::padding. * gtk/gtkcontainer.c: make ::border_width an INT property. * gtk/gtkpacker.c: make ::position an INT property. * gtk/gtkscrolledwindow.c (gtk_scrolled_window_adjustment_changed): guard against NULL h/v scrollbars, since this is used at construction time. * gtk/gtkclist.[hc]: nuked gtk_clist_construct(), implemented internal gtk_clist_constructor(). * gtk/gtkctree.[hc]: nuked gtk_ctree_construct(), implemented gtk_ctree_constructor(). * gtk/gtkprogressbar.c (gtk_progress_bar_class_init): property ::pulse_step should use ARG_PULSE_STEP, not ARG_FRACTION. * docs/reference/Makefile.am: fun stuff, disabled docs generation again, gtk-scan.c needs to introspec paramspecs, not GtkAgs. * gtk/gtkwidget.[hc]: removed gtk_widget_setv(), gtk_widget_getv(), gtk_widget_newv() and gtk_widget_get(). (gtk_widget_new): use g_object_new_valist(). (gtk_widget_set): use g_object_set_valist(). * gtk/gtkobject.[hc]: removed gtk_object_arg_get_info(), gtk_object_getv(), gtk_object_query_args(), gtk_object_newv(), gtk_object_class_add_signals(), gtk_object_class_user_signal_new(), gtk_object_class_user_signal_newv(), gtk_object_arg_set(), gtk_object_arg_get(), gtk_object_args_collect(), gtk_object_default_construct(), gtk_object_constructed(), GTK_CONSTRUCTED and GTK_OBJECT_CONSTRUCTED(). removed nsignals, signals and n_args members from GtkObjectClass. (gtk_object_new): use g_object_new_valist(). (gtk_object_set): use g_object_set_valist(). (gtk_object_get): use g_object_get_valist(). * gtk/gtkcompat.h: define gtk_object_default_construct(). * gtk/gtktypeutils.c (gtk_type_new): create constructed objects via g_object_new(). * gtk/*.c: removed gtk_object_class_add_signals() from class_init() fucntions, cleaned up method assignments (make sure your structures are setup properly before calling out). removed all GTK_CONSTRUCTED hacks ;)
