	* gtk/gtkvscrollbar.c:
	(gtk_vscrollbar_draw_step_back):
	(gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for
 	gtk_paint_arrow, to be consistent with hscrollbar.

	added construct args ::hadjustment, ::vadjustment.
	added args ::line_wrap, ::word_wrap.
	(gtk_text_class_init): added scroll_adjustments signal.
	(gtk_text_new): use gtk_widget_new.
	(gtk_text_disconnect): remove adjustement with gtk_text_set_adjustments,
	so we don't screw the reference counts and don't leave signals connected.
 	(gtk_text_destroy): disconnect adjustments signals.
 	(gtk_text_finalize): unref adjustments.

	* gtk/gtkctree.c: added construct args ::n_columns and ::tree_column.
	added args ::indent, ::spacing, ::show_stub, ::reorderable,
 	::use_drag_icons, ::line_style and ::expander_style.
	(gtk_ctree_set_show_stub): renamed from gtk_ctree_show_stub, which is
	deprecated now.

 	removed ::vadjustment and ::hadjustment args, introduced
 	::scroll_adjustments signal.
	added ::shadow_type, ::selection_mode and ::row_height args.
	added n_columns construct arg.
	(gtk_clist_construct): call gtk_object_constructed().
 	(gtk_clist_set_row_height): if height is passed as 0,
	revert to automatic height calculation.
	(gtk_clist_destroy): before unrefing the adjustments, disconnect our
	signal handlers.

Fri Nov 21 22:34:58 1998  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct
	like gtk_object_new.
	(gtk_widget_destroy): assert that we only destroy constructed widgets.

	* gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY
	to identify args that may only be used for construction.
	GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction
	time.
	* gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct
	at the end if the object is not fully constructed.
	(gtk_object_newv): likewise.
	(gtk_object_destroy): assert that we only destroy constructed objects.
 	(gtk_object_init): setup GTK_CONSTRUCTED from the
	objects real klass.
	(gtk_object_default_construct): new function to complete default
	construction of an object by applying missing construtor args with
	default values of 0, 0.0 or NULL.
	(gtk_object_constructed): new function to mark an object as being
	constructed (used from within constructors).

	* gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer
	so it is immediatedly available for the caller.

	* gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to
	the object initilizer (GtkObjectInitFunc takes a second arg now, the
 	real klass), and asure that object initializers may temporarily alter
	the class pointer.

Fri Nov 20 08:00:30 1998  Tim Janik  <timj@gtk.org>

	* gtk/testgtk.c: change all occourances of gtk_container_add (
	scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...)
	for widget!=(clist, ctree, text, viewport).

	* gtk/gtkcombo.c:
 	(gtk_combo_init): use gtk_scrolled_window_add_with_viewport()
	to add children to the scrolled window.

	* gtk/gtkscrolledwindow.h:
	* gtk/gtkscrolledwindow.c:
	changed scrolled_window->viewport to scrolled_window->child, and use
	gtk_widget_scroll_adjustements() to set the scroll adjustments for the
	widget, we do not create an additional viewport anymore.
	added ::hadjustment and ::vadjustment constructor args.
 	(gtk_scrolled_window_new): use gtk_widget_new() to create the widget.
	(gtk_scrolled_window_set_hadjustment):
	(gtk_scrolled_window_set_vadjustment): new functions that superceed
	gtk_scrolled_window_construct.
	(gtk_scrolled_window_construct): deprecated this function.

	* gtk/gtkhscrollbar.c:
	* gtk/gtkvscrollbar.c:
	* gtk/gtkhscale.c:
	* gtk/gtkvscale.c:
	support a constructor arg "::adjustment", and use gtk_widget_new() for
	the widget creation.

	* gtk/gtkrange.c: added ::update_policy arg.
 	(gtk_range_set_adjustment): if adjustment is passed in as NULL, create
 	a default adjustment so this function can be used for derived widgets
 	that depend on the adjustment's existance.
	(gtk_range_destroy): disconnect the adjustment signal, so we don't
	get called after we got destroyed, we don't destroy the adjustment
	in here, because it might have been provided from another widget.

	* gtk/gtkviewport.c: introduced ::scroll_adjustments signal.
	(gtk_viewport_destroy): same as gtk_range_destroy.

	* gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy.

	* gtk/gtkwidget.h:
	* gtk/gtkwidget.c: changed gtk_widget_activate() to return a
	gboolean, indicating whether this widget supports activation.
	added gtk_widget_scroll_adjustements() to set the scrolling
	adjustments of a widget.

Wed Nov 19 01:22:42 1998  Tim Janik  <timj@gtk.org>

	* gtk/gtkoptionmenu.c:
 	(gtk_option_menu_remove_contents):
	(gtk_option_menu_update_contents): removed
 	gtk_container_[un]block_resize() pairs.

	* gtk/gtknotebook.h:
	* gtk/gtknotebook.c: removed the tab_border field, since it shouldn't
	be used outside of gtknotebook.c anyways. made ARG_TAB_BORDER a
	wrtie-only argument.

	* *.c: made deprecated functions issue a message:
	gtk_clist_set_border, gtk_container_block_resize,
 	gtk_container_unblock_resize, gtk_container_need_resize,
 	gtk_object_class_add_user_signal, gtk_spin_button_construct,
	gtk_scrolled_window_construct.
	removed non-functional functions:
	gtk_container_disable_resize, gtk_container_enable_resize,
	gtk_clist_set_policy.

Wed Nov 18 22:54:36 1998  Tim Janik  <timj@gtk.org>
