doh, this was broken beyond believe. 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 ;)

(gtk_tree_model_sort_set_compare): this had the wrong signature * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_set_attributes): Fix the docs to say that it destructively replaces existing attributes (previously said that it added attributes). (gtk_tree_view_column_set_visible): canonicalize bool before equality testing. Also, check for realization before hiding/showing the tree_column->window; if this window could exist before realization, then it's busted and needs fixing, we can't create GDK resources pre-realization. Also, remove superfluous queue_resize(), since set_size() does that for us. (gtk_tree_view_column_set_col_type): check realization before using tree_column->window * gtk/gtktreedatalist.c: fix filename in copyright notice

Instead store all the specific text attributes. Separate whether an attribute is enabled from its value. Sync all properties with GtkTextTag, make them all consistent, etc. * gtk/gtkcellrenderer.h: Add a flag GTK_CELL_RENDERER_SORTED so renderers can highlight the sort row/column * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_get_property): use accessor functions to get values; this has the side effect of showing up which accessor functions were missing.

(gtk_tree_view_column_set_visible): canonicalize bool before equality testing. Also, check for realization before hiding/showing the tree_column->window; if this window could exist before realization, then it's busted and needs fixing, we can't create GDK resources pre-realization. Also, remove superfluous queue_resize(), since set_size() does that for us.
