Fri May 12 17:13:32 2000  Tim Janik  <timj@gtk.org>

	* docs/Changes-1.4.txt: documented necessary changes for 1.4 transition.

	* gtk/gtktext.c: made the adjustments no-construct args, simply
	provide default adjustments.
	(gtk_text_destroy): release adjustments.

	* gtk/gtkprogressbar.c (gtk_progress_bar_class_init): made the
	adjustment argument non-construct.

	* gtk/gtkprogress.c (gtk_progress_destroy): release adjustment here,
	instead of in finalize.
	(gtk_progress_get_text_from_value):
	(gtk_progress_get_current_text):
	(gtk_progress_set_value):
	(gtk_progress_get_percentage_from_value):
	(gtk_progress_get_current_percentage):
	(gtk_progress_set_percentage):
	(gtk_progress_configure): ensure an adjustment is present.

Thu May 11 01:24:08 2000  Tim Janik  <timj@gtk.org>

	* gtk/gtkcolorsel.[hc]:
	* gtk/gtkcolorseldialog.[hc]:
	* gtk/gtkhsv.[hc]: major code cleanups, destroy handlers need to chain
	their parent implementation, use bit fields for boolean values, don't
	create unused widgets, usage of glib types, braces go on their own
	lines, function argument alignment, #include directives etc. etc. etc..

	* gtk/Makefile.am (gtk_public_h_sources): install gtkhsv.h.

Wed May 10 23:29:52 2000  Tim Janik  <timj@gtk.org>

	* gtk/gtktoolbar.c (gtk_toolbar_destroy): don't unref a NULL tooltips.

	* gtk/gtkfilesel.c (gtk_file_selection_destroy): don't free a cmpl_state
	of NULL.

	* gtk/gtkcombo.c (gtk_combo_item_destroy): don#t keep references
	to freed data.
	(gtk_combo_destroy): don't keep a pointer to a destroyed window.

	* gtk/gtkmenu.c (gtk_menu_init): reset the menu's toplevel pointer
	to NULL when the toplevel is getting destroyed.
	(gtk_menu_set_tearoff_state): same here for the tearoff_window.
	(gtk_menu_destroy):
	(gtk_menu_init): store the information of whether we have to
	readd the initial child ref_count during destruction in a new
	GtkMenu field needs_destruction_ref_count.

	* gtk/gtkviewport.c: SHAME! ok this one is tricky, so i note it
	here, those reading: learn from my mistake! ;)
	in order for set_?adjustment to support a default adjustemnt if
	invoked with an adjustment pointer of NULL, the code read (pseudo):
	if (v->adjustment) unref (v->adjustment);
	if (!adjustment) adjustment = adjustment_new ();
	if (v->adjustment != adjustment) v->adjustment = ref (adjustment);
	now imagine the first unref to actually free the old adjustment and
	adjustment_new() creating a new adjustment from the very same memory
	portion. here, the latter comparision will unintendedly fail, and
	all hell breaks loose.
	(gtk_viewport_set_hadjustment):
	(gtk_viewport_set_vadjustment): reset viewport->?adjustment to NULL
	after unreferencing it.

	* gtk/gtkcontainer.[hc]: removed toplevel registration
	functions: gtk_container_register_toplevel(),
	gtk_container_unregister_toplevel() and
	gtk_container_get_toplevels() which had wrong semantics
	anyways: it didn't reference and copy the list.

	* gtk/gtkwindow.c: we take over the container toplevel registration
	bussiness now. windows are registered across multiple destructions,
	untill they are finalized. the initial implicit reference count
	users are holding on windows is removed with the first destruction
	though.
	(gtk_window_init): ref & sink and set has_user_ref_count, got
	rid of gtk_container_register_toplevel() call. add window to
	toplevel_list.
	(gtk_window_destroy): unref the window if has_user_ref_count
	is still set, got rid of call to
	gtk_container_unregister_toplevel().
	(gtk_window_finalize): remove window from toplevel list.
	(gtk_window_list_toplevels): new function to return a newly
	created list with referenced toplevels.
	(gtk_window_read_rcfiles): use gtk_window_list_toplevels().

	* gtk/gtkhscale.c (gtk_hscale_class_init): made the GtkRange
	adjustment a non-construct arg.
	* gtk/gtkvscale.c (gtk_vscale_class_init): likewise.
	* gtk/gtkhscrollbar.c (gtk_vscrollbar_class_init): likewise.
	* gtk/gtkvscrollbar.c (gtk_vscrollbar_class_init): likewise.

	* gtk/gtkrange.c: added some realized checks.
	(gtk_range_destroy): get rid of the h/v adjustments in the
	destroy handler instead of finalize. remove timer.
	(gtk_range_get_adjustment): demand create adjustment.

	* gtk/gtkviewport.c: made h/v adjustment non-construct args.
	we simply create them on demand now and get rid of them in
	the destroy handler.
	(gtk_viewport_destroy): get rid of the h/v adjustments in the
	destroy handler instead of finalize.
	(gtk_viewport_get_hadjustment):
	(gtk_viewport_get_vadjustment):
	(gtk_viewport_size_allocate): demand create h/v adjustment
	if required.

	* gtk/gtkwidget.c (gtk_widget_finalize): duplicate part of the
	gtk_widget_real_destroy () functionality.
	(gtk_widget_real_destroy): reinitialize with a new style, instead
	of setting widget->style to NULL.

Fri May  5 13:02:09 2000  Tim Janik  <timj@gtk.org>

	* gtk/gtkcalendar.c:
	* gtk/gtkbutton.c: ported _get_type() implementation over to
	GType, either to preserve memchunks allocation facilities,
	or because Gtk+ 1.0 GtkTypeInfo was still being used.

	* gtk/gtkobject.[hc]: derive from GObject. ported various functions
	over. prepare for ::destroy to be emitted multiple times.
	removed reference tracer magic. chain into GObjectClass.shutdown()
	to emit ::destroy signal.

	* gtk/gtksignal.c: removed assumptions about GTK_TYPE_OBJECT being
	fundamental.

	* gtk/gtkmain.c: removed gtk_object_post_arg_parsing_init()
	cludge.

	* gtk/gtksocket.c:
	* gtk/gtkplug.c:
	* gtk/gtklayout.c:
	* gtk/gtklabel.c:
	* gtk/gtkargcollector.c:
	* gtk/gtkarg.c: various fixups to work with GTK_TYPE_OBJECT
	not being a fundamental anymore, and to work with the new
	type system (nuked fundamental type varargs clutter).

	* gtk/*.c: install finalize handlers in the GObjectClass
	part of the class structure.
	changed direct GTK_OBJECT()->klass accesses to
	GTK_*_GET_CLASS().
	changed direct object_class->type accesses to GTK_CLASS_TYPE().

	* gtktypeutils.[hc]: use the reserved fundamental ids provided by
	GType. made most of the GTK_*() type macros and Gtk* typedefs
	simple wrappers around macros and types provided by GType.
	most notably, a significant portion of the old API vanished:
	GTK_TYPE_MAKE(),
	GTK_TYPE_SEQNO(),
	GTK_TYPE_FLAT_FIRST, GTK_TYPE_FLAT_LAST,
	GTK_TYPE_STRUCTURED_FIRST, GTK_TYPE_STRUCTURED_LAST,
	GTK_TYPE_ARGS,
	GTK_TYPE_CALLBACK,
	GTK_TYPE_C_CALLBACK,
	GTK_TYPE_FOREIGN,
	GtkTypeQuery,
	gtk_type_query(),
	gtk_type_set_varargs_type(),
	gtk_type_get_varargs_type(),
	gtk_type_check_object_cast(),
	gtk_type_check_class_cast(),
	gtk_type_describe_tree(),
	gtk_type_describe_heritage(),
	gtk_type_free(),
	gtk_type_children_types(),
	gtk_type_set_chunk_alloc(),
	gtk_type_register_enum(),
	gtk_type_register_flags(),
	gtk_type_parent_class().
	replacements, where available are described in ../docs/Changes-1.4.txt.
	implemented compatibility functions for the remaining API.

	* configure.in: depend on glib 1.3.1, use gobject module.

Incompatible Changes from GTK+-1.2 to GTK+-1.4:
- The gdk_time* functions have been removed. This functionality
* The gdk_time* functions have been removed. This functionality
has been unused since the main loop was moved into GLib
prior to 1.2.
- The signature for GtkPrintFunc (used for gtk_item_factory_dump_items)
* The signature for GtkPrintFunc (used for gtk_item_factory_dump_items)
has been changed to take a 'const gchar *' instead of 'gchar *', to
match what we do for glib, and other similar cases.
- The detail arguments in the GtkStyleClass structure are now 'const gchar *'.
* The detail arguments in the GtkStyleClass structure are now 'const gchar *'.
- gtk_paned_set_gutter_size() has been removed, since the small handle tab
* gtk_paned_set_gutter_size() has been removed, since the small handle tab
has been changed to include the entire area previously occupied by
the gutter.
- GDK no longer selects OwnerGrabButtonMask for button presses. This means
* GDK no longer selects OwnerGrabButtonMask for button presses. This means
that the automatic grab that occurs when the user presses a button
will have owner_events = FALSE, so all events are redirected to the
grab window, even events that would normally go to other windows of the
window's owner.
- The detail arguments in the GtkStyleClass structure are now 'const gchar *'.
* GtkColorSelectionDialog has now been moved into it's own set of files,
gtkcolorseldialog.c and gtkcolorseldialog.h.
- GtkColorSelectionDialog has now been moved into it's own set of files,
gtkcolorseldialog.c and gtkcolorseldialog.h.
* Type system changes:
- GTK_TYPE_OBJECT is not a fundamental type anymore. Type checks of the
style (GTK_FUNDAMENTAL_TYPE (some_type) == GTK_TYPE_OBJECT)
will not work anymore. As a replacement, (GTK_TYPE_IS_OBJECT (some_type))
can be used now.
- The following types vanished: GTK_TYPE_ARGS, GTK_TYPE_CALLBACK,
GTK_TYPE_C_CALLBACK, GTK_TYPE_FOREIGN. With them, the corresponding GtkARg
fields and field access macros vanished as well.
- The following type aliases vanished: GTK_TYPE_FLAT_FIRST,
GTK_TYPE_FLAT_LAST, GTK_TYPE_STRUCTURED_FIRST, GTK_TYPE_STRUCTURED_LAST.
- The type macros GTK_TYPE_MAKE() and GTK_TYPE_SEQNO() vanished, use of
GTK_FUNDAMENTAL_TYPE() is discouraged. Instead, the corresponding GType
API should be used: G_TYPE_FUNDAMENTAL(), G_TYPE_DERIVE_ID(),
G_TYPE_BRANCH_SEQNO(). Note that the GLib type system doesn't build new
type ids based on a global incremental sequential number anymore, but
numbers new type ids sequentially per fundamental type branch.
- The following type functions vanished/were replaced:
Old Function Replacement
gtk_type_query() - being investigated -
gtk_type_set_varargs_type() -
gtk_type_get_varargs_type() -
gtk_type_check_object_cast() g_type_check_instance_cast()
gtk_type_check_class_cast() g_type_check_class_cast()
gtk_type_describe_tree() -
gtk_type_describe_heritage() -
gtk_type_free() -
gtk_type_children_types() g_type_children()
gtk_type_set_chunk_alloc() GTypeInfo.n_preallocs
gtk_type_register_enum() g_enum_register_static()
gtk_type_register_flags() g_flags_register_static()
gtk_type_parent_class() g_type_parent() / g_type_class_peek_parent()
Use of g_type_class_ref() / g_type_class_unref() and g_type_class_peek()
is recommended over usage of gtk_type_class().
Use of g_type_register_static() / g_type_register_dynamic() is recommended
over usage of gtk_type_unique().
* Object system changes:
GtkObject derives from GObject, it is not the basic object type anymore.
This imposes the following source incompatible changes:
- GtkObject has no klass field anymore, an object's class can be retrived
with the object's coresponding GTK_<OBJECT>_GET_CLASS (object) macro.
- GtkObjectClass has no type field anymore, a class's type can be retrived
with the GTK_CLASS_TYPE (class) macro.
- GtkObjectClass does not introduce the finalize() or shutdown() method
anymore. While shutdown() is intended for Gtk internal use only, finalize()
is required by a variety of object implementations. GObjectClass.finalize
should be overriden here, e.g.:
static void gtk_label_finalize (GObject *gobject)
{
GtkLabel *label = GTK_LABEL (gobject);
G_OBJECT_CLASS (parent_class)->finalize (object);
}
static void gtk_label_class_init (GtkLabelClass *class)
{
GObjectClass *gobject_class = G_OBJECT_CLASS (class);
gobject_class->finalize = gtk_label_finalize;
}
- the GtkObject::destroy signal can be emitted multiple times on an object
now. ::destroy implementations have to take this into account by
conditionalising freeing/release of assorted resources, e.g.:
if (object->foo_data)
{
g_free (object->foo_data);
object->foo_data = NULL;
}
Also, ::destroy implementations have to release peding object references,
that is, code portions commonly found in finalize implementations like:
if (object->adjustment)
{
gtk_object_unref (object->adjustment);
object->adjustment = NULL;
}
have to be moved into the ::destroy implementations.
This is required to break object reference cycles at destruction time.
