-DON'T EDIT THIS FILE - changes are now maintained in the reference
-manual, see docs/reference/gtk/changes-*.sgml. Also, when adding a
-change to the manual, you should amend the docs for all
-newly-deprecated features to point to the replacement for that
-feature, and be sure the GTK_DISABLE_DEPRECATED guards are in place in
-the header files. Be sure to add a note to the docs for EACH
-deprecated function; don't just do the changes-*.sgml change.

-Incompatible Changes from GTK+-1.2 to GTK+-2.0:
-
-* gtk_container_get_toplevels() was removed and replaced with
- gtk_window_list_toplevels(), which has different memory management
- on the return value (gtk_window_list_toplevels() copies the GList
- and also references each widget in the list, so you have to
- g_list_free() the list after first unref'ing each list member).
-
-* 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)
- 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 *'.
-
-* 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.
-
-* gtk_paned_set_handle_size() has been removed, in favor of a style property,
- since this is an option that only makes sense for themes to adjust.
-
-* 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.
-
-* GtkColorSelectionDialog has now been moved into it's own set of files,
- gtkcolorseldialog.c and gtkcolorseldialog.h.
-
-* gtk_widget_shape_combine_mask() now keeps a reference count on the
- mask pixmap that is passed in.
-
-* the GtkPatternSpec has been moved to glib as GPatternSpec, the pattern
- arguments to gtk_item_factory_dump_items() and gtk_item_factory_dump_rc()
- have thusly been changed to take a GPatternSpec instead of GtkPatternSpec.
-
-* 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. The corresponding GtkArg
- fields and field access macros are also gone.
- - 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, so 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() and shutdown() methods
- 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 now be emitted multiple times on an object.
- ::destroy implementations should check that make sure that they take this
- into account, by checking to make sure that resources are there before
- freeing them. For example:
- if (object->foo_data)
- {
- g_free (object->foo_data);
- object->foo_data = NULL;
- }
-
- Also, ::destroy implementations have to release object references that
- the object holds. Code in finalize implementations such as:
- if (object->adjustment)
- {
- gtk_object_unref (object->adjustment);
- object->adjustment = NULL;
- }
- have to be moved into the ::destroy implementations. The reason for doing
- this is that all object reference cycles should be broken at destruction
- time.
-
- Because the ::destroy signal can be emitted multiple times, it no longer
- makes sense to check if a widget has been destroyed using the
- GTK_OBJECT_DESTROYED() macro, and this macro has been removed. If
- catching destruction is still needed, it can be done with a signal
- connection to ::destroy.
-
-* Signal system changes:
- The Gtk 2.0 signal merly proxies the GSignal system now.
- For future usage, direct use of the GSignal API is recommended,
- this avoids significant performance hits where GtkArg structures
- have to be converted into GValues. For language bindings,
- GSignal+GClosure provide a much more flexible and convenient
- mechanism to hook into signal emissions or install class default
- handlers, so the old GtkSignal API for language bindings is not
- supported anymore.
- Functions that got removed in the Gtk signal API:
- gtk_signal_n_emissions(), gtk_signal_n_emissions_by_name(),
- gtk_signal_set_funcs(), gtk_signal_handler_pending_by_id(),
- gtk_signal_add_emission_hook(), gtk_signal_add_emission_hook_full(),
- gtk_signal_remove_emission_hook(), gtk_signal_query().
- Also, the GtkCallbackMarshal argument to gtk_signal_connect_full() is
- not supported anymore.
- For many of the removed functions, similar variants are available
- in the g_signal_* namespace.
- The GSignal system perfomrs emissions in a slightly different manner than
- the old GtkSignal code. Signal handlers that are connected to signal "foo"
- on object "bar" while "foo" is being emitted, will not be called anymore
- during the emission they were connected within.
-
-* Inserting and deleting text in GtkEntry though functions such
- as gtk_entry_insert_text() now leave the cursor at its original
- position in the text instead of moving it to the location of
- the insertion/deletion.
-
-* The ->label field of GtkFrame widgets has been removed. (As part of
- a change to allow the arbitrary widgets in the title position.) The
- text can now be retrieved with the new function gtk_frame_get_text().
-
-* The 'font' and 'font_set' declarations in RC files are now ignored. There
- is a new 'font_name' field that holds the string form of a Pango font
-
-* A number of types in GDK have become subclasses of GObject. For the
- most part, this should not break anyone's code. However, it's now
- possible/encouraged to use g_object_ref()/g_object_unref() and other
- GObject features with these GDK types. The converted types are:
- GdkWindow, GdkDrawable, GdkPixmap, GdkImage, GdkGC, GdkDragContext,
- GdkColormap
-
-* All drawables including pixmaps used to have a type tag, the
- GdkWindowType enumeration, which included GDK_WINDOW_PIXMAP.
- GdkWindowType is now a property of GdkWindow _only_, and there is
- no GDK_WINDOW_PIXMAP. You can use the GDK_IS_PIXMAP() macro to see
- if you have a pixmap, if you need to know that.
-
-* GtkStyle and GtkRcStyle are now subclasses of GObject as well. This
- requires fairly extensive changes to theme engines quite badly, but
- shouldn't affect most other code.
-
-* xthickness/ythickness have moved from GtkStyleClass to GtkStyle
- (from class to instance). This gives themes a bit more flexibility
- and is generally more of the Right Thing. You can trivially fix
- your code with s/style->klass->xthickness/style->xthickness/g and
- same for ythickness.
-
-* Some GtkStyle draw_ methods have been removed (cross, oval, ramp)
- and others have been added (expander, layout). This will require
- changes to theme engines.
-
-* If you were using private GDK types, they have been rearranged
- significantly. You shouldn't use private types. ;-)
-
-* The visual for a widget, and also the default visual is now derived
- from the colormap for the widget and the default colormap.
- gtk_widget_set_visual(), gtk_widget_set_default_visual(), gtk_widget_push_visual()
- and gtk_widget_pop_visual() now do nothing. Since the visual always
- had to match that of the colormap, it is safe to simply delete
- all references to these functions.
-
-* A number of functions in GDK have been renamed for consistency and
- clarity. #defines to provide backwards compatibility have been
- included, but can be disabled by defineing GDK_DISABLE_DEPRECATED.
-
- #define gdk_draw_pixmap gdk_draw_drawable
- #define gdk_draw_bitmap gdk_draw_drawable
-
- #define gdk_window_get_size gdk_drawable_get_size
- #define gdk_window_get_type gdk_window_get_window_type
- #define gdk_window_get_colormap gdk_drawable_get_colormap
- #define gdk_window_set_colormap gdk_drawable_set_colormap
- #define gdk_window_get_visual gdk_drawable_get_visual
-
- #define gdk_window_ref gdk_drawable_ref
- #define gdk_window_unref gdk_drawable_unref
- #define gdk_bitmap_ref gdk_drawable_ref
- #define gdk_bitmap_unref gdk_drawable_unref
- #define gdk_pixmap_ref gdk_drawable_ref
- #define gdk_pixmap_unref gdk_drawable_unref
-
- #define gdk_gc_destroy gdk_gc_unref
- #define gdk_image_destroy gdk_image_unref
- #define gdk_cursor_destroy gdk_cursor_unref
-
- (Note that g_object_ref() and g_object_unref() may be used for all of
- the above _ref and _unref functions.)
-
- #define gdk_window_copy_area(drawable,gc,x,y,source_drawable,source_x,source_y,width,height) \
- gdk_draw_pixmap(drawable,gc,source_drawable,source_x,source_y,x,y,width,height)
-
- #define gdk_rgb_get_cmap gdk_rgb_get_colormap
-
- gtk_widget_popup() was removed, it was only usable for GtkWindows, and
- there the same effect can be achived by gtk_widget_set_uposition() and
- gtk_widget_show().
-
-* gdk_pixmap_foreign_new() no longer calls XFreePixmap() on the
- pixmap when the GdkPixmap is finalized. This change corresponds
- to the behavior of gdk_window_foreign_new(), and fixes a lot
- of problems with code where the pixmap wasn't supposed to be
- freed. If XFreePixmap() is needed, it can be done using the
- destroy-notification facilities of g_object_set_data().
-
-* GtkProgress/GtkProgressBar had serious problems in GTK 1.2.
- - Only 3 or 4 functions are really needed for 95% of progress
- interfaces; GtkProgress[Bar] had about 25 functions, and
- didn't even include these 3 or 4.
- - In activity mode, the API involves setting the adjustment
- to any random value, just to have the side effect of
- calling the progress bar update function - the adjustment
- is totally ignored in activity mode
- - You set the activity step as a pixel value, which means to
- set the activity step you basically need to connect to
- size_allocate
- - There are ctree_set_expander_style()-functions, to randomly
- change look-and-feel for no good reason
- - The split between GtkProgress and GtkProgressBar makes no sense
- to me whatsoever.
- This was a big wart on GTK and made people waste lots of time,
- both learning and using the interface.
- So, we have added what we feel is the correct API, and marked all the
- rest deprecated. However, the changes are 100% backward-compatible and
- should break no existing code.
- The following 5 functions are the new programming interface and you
- should consider changing your code to use them:
- void gtk_progress_bar_pulse (GtkProgressBar *pbar);
- void gtk_progress_bar_set_text (GtkProgressBar *pbar,
- const gchar *text);
- void gtk_progress_bar_set_fraction (GtkProgressBar *pbar,
- gfloat fraction);
-
- void gtk_progress_bar_set_pulse_step (GtkProgressBar *pbar,
- gfloat fraction);
- void gtk_progress_bar_set_orientation (GtkProgressBar *pbar,
- GtkProgressBarOrientation orientation);
-
-* The GtkNotebookPage structure has been removed from the public header files;
- this was never meant to be a public structure, and all functionality that
- could be done by accessing the struct fields of this structure should be
- accesible otherwise.
-
-* GtkMenuPositionFunc has a new parameter push_in which controls how
- menus placed outside the screen is handled. If this is set to true and
- part of the menu is outside the screen then Gtk+ pushes it into the visible
- area. Otherwise the menu is cut of at the end of the visible screen area.
-
- Regardles of what happens to the size of the menu, the result is always
- that the items are placed in the same place as if the menu was placed
- outside the screen, using menu scrolling if necessary.
-
-* The "draw" signal and virtual method on GtkWidget has been removed.
- All drawing should now occur by invalidating a region of the widget
- (call gdk_window_invalidate_rect() or gtk_widget_queue_draw() for
- example to invalidate a region). GTK+ merges all invalid regions,
- and sends expose events to the widget in an idle handler for the
- invalid regions. gtk_widget_draw() is deprecated but still works; it
- adds the passed-in area to the invalid region and immediately sends
- expose events for the current invalid region.
- Most widgets will work fine if you just delete their "draw"
- implementation, since they will already have working expose_event
- implementations. The draw method was rarely called in practice
- anyway.
-
-* The GdkExposeEvent has a new region field. This can be used instead
- of the area field if you want a more exact representation of the
- area to update.
-
-* Sending synthetic exposes using gtk_widget_event is no longer allowed.
- If you just need an expose call you should use gdk_window_invalidate_rect()
- or gdk_window_invalidate_region() instead. For the case of container
- widgets that need to propagate expose events to NO_WINDOW children
- you can either use gtk_container_propagate_expose(), or chain to the
- default container expose handler.
-
-* The draw_default and draw_focus methods/signals on GtkWidget are
- gone; simply draw things in your expose handler.
- gtk_widget_draw_focus() and gtk_widget_draw_default() wrapper
- functions are also gone; just queue a draw on the widget,
- or the part affected by the focus/default anyway.
- Also, GtkWidget now has default implementations for focus_in_event
- and focus_out_event. These set/unset GTK_HAS_FOCUS, and queue a
- draw. So if your focus in/out handler just does that, you can delete
- it.
-
-* GtkText and GtkTree are buggy and broken. We don't recommend using
- them, and changing old code to avoid them is a good idea. The
- recommended alternatives are GtkTextView and GtkTreeView. The
- broken widgets are not declared in the headers by default; to use
- them, define the symbol GTK_ENABLE_BROKEN during compilation. In
- some future release, these widgets will be removed from GTK+.
-
-* GdkColorContext is gone; you probably weren't using it anyway.
- Use GdkColormap and the gdk_rgb_* functions instead.
-
-* GtkMenuBar now draws the GtkContainer::border_width space outside
- the frame, not inside the frame
-
-* In GTK 1.2, if an event handler returned TRUE it prevented
- propagation of that event to parent widgets. That is, the
- event signal would not be emitted on parent widgets. In
- GTK 2.0, if an event handler returns TRUE, the current signal
- emission on the current widget is immediately stopped. That is,
- other callbacks connected to the signal will not be invoked.
-
-* gtk_toolbar_new() no longer has arguments. This function
- was broken because the default GtkToolbarStyle (icons, text, both)
- is now a user preference, which is overridden when you call
- gtk_toolbar_set_style(). The constructor forced everyone to
- override the preference, which was undesirable. So to port
- your app, decide if you want to force the toolbar style
- or conform to the user's global defaults; if you want to force
- it, call gtk_toolbar_set_style().
-
- The orientation arg was removed from toolbar_new() as well, just
- because it wasn't very useful and we were breaking the function
- anyway so had an opportunity to lose it. Call
- gtk_toolbar_set_orientation() to set toolbar orientation.
-
-* GtkRange/GtkScrollbar/GtkScale were rewritten; this means that most
- theme engines won't draw them properly, and any custom subclasses of
- these widgets will need a rewrite (though if you could figure out
- how to subclass the old version of GtkRange, you have our
- respect). Also, GtkTroughType is gone.
-
-* The GtkContainer::focus signal/virtualfunction and
- gtk_container_focus() call were replaced by
- GtkWidget::focus and gtk_widget_child_focus().
- The semantics are the same, so you should be able to just
- replace "container_class->focus = mywidget_focus" with
- "widget_class->focus = mywidget_focus" and replace
- gtk_container_focus() calls with gtk_widget_child_focus() calls.
-
- The purpose of this change was to allow non-containers to have
- focusable elements.
-
-* gtk_rc_set_image_loader() and gtk_rc_load_image() has been removed, now
- that GTK+ includes decent image loading capabilities itself.
-
-* An extra GtkSettings argument has been added to
- gtk_rc_find_pixmap_in_path(). This function is only actually useful
- from a theme engine during parsing, at which point the GtkSettings
- is provided.
-
-* The child argument facility in gtkcontainer.c has been converted
- to a child property facility using GParamSpec and other facilities
- for GObject.
-
- - The set_child_arg and get_child_arg virtual methods have been
- replaced with set_child_property / get_child_property, which
- work similar to GObject->set_property/get_property.
-
- - Other removed functions with the replacements:
-
- gtk_container_add_child_arg_type => gtk_container_class_install_child_property
- gtk_container_query_child_args => gtk_container_class_list_child_properties
- gtk_container_child_getv => gtk_container_child_set_property
- gtk_container_child_setv => gtk_container_child_get_property
- gtk_container_add_with_args => gtk_container_add_with_properties
- gtk_container_addv => gtk_container_add / gtk_container_child_set_property
-
-* gdk_image_get() (or rather its replacement,
- gdk_drawable_get_image()) now handles errors properly by returning
- NULL, previously it would crash. Also, a window being offscreen is
- no longer considered an error; instead, the area being contains
- undefined contents for the offscreen areas. In most cases, code
- using gdk_image_get() should really be ported to
- gdk_pixbuf_get_from_drawable().
-
-* gtk_widget_set_usize() has been renamed to
- gtk_widget_set_size_request(), however the old name still exists
- unless you define GTK_DISABLE_DEPRECATED.
-
-* gtk_widget_set_uposition() is deprecated; use gtk_window_move(),
- gtk_fixed_put(), or gtk_layout_put() instead.
-
-* gtk_window_set_policy() is deprecated. To get the effect of
- "allow_shrink", call gtk_widget_set_size_request(window, 0, 0). To
- get the effect of "allow_grow", call
- gtk_window_set_resizable(window, TRUE). You didn't want the effect
- of auto_shrink, it made no sense. But maybe if you were using it you
- want to use gtk_window_resize (window, 1, 1) to snap a window back
- to its minimum size (the 1, 1 will be rounded up to the minimum
- window size).
-
-* The core GTK+ now takes care of handling mapping, unmapping and
- realizing the child widgets of containers in
- gtk_widget_set_parent(). In most cases, this allows container
- implementations to be simplifid by removing the code in add()
- methods to map and realize children. However, there are
- a couple of things to watch out for here:
-
- - If the parent is realized before the add() happens,
- gtk_widget_set_parent_window() must be called before
- gtk_widget_set_parent(), since gtk_widget_set_parent()
- will realize the child.
-
- - If a container depended on its children not being mapped
- unless it did so itself (for example, GtkNotebook only
- mapped the current page), then the new function
- gtk_widget_set_child_visible() must be called to keep
- widgets that should not be mapped not mapped.
-
- As part of this change, most containers also will no longer need
- custom implementations of the map() and unmap() virtual
- functions. The only cases where this is necessary are:
-
- - For !NO_WINDOW widgets, if you create children of widget->window
- and don't map them in realize() then you must map them
- in map(). [ In almost all cases, you can simply map the
- windows in realize() ]
-
- - For NO_WINDOW widgets, if you create windows in your realize()
- method, you must map then in map() and unmap them in unmap().
-
-* gtk_widget_set_default_style (), gtk_widget_push_style (),
- and gtk_widget_pop_style () have been removed, since they
- did not work properly with themes and there were better
- alternatives for modifying the appearance of widgets.
-
- You should generally use gtk_widget_modify_fg/bg/base/text/font
- instead.
-
-* gtk_image_new() now takes no arguments and creates an empty GtkImage
- widget. To create a GtkImage widget from a GdkImage (the least
- common usage of GdkImage), use gtk_image_new_from_image.
-
-* GTK_SELECTION_EXTENDED is now deprecated, and neither the
- GtkList/GtkTree nor the GtkCList/GtkCTree support
- GTK_SELECTION_EXTENDED anymore. However, the old extended behavior
- replaces MULTIPLE behavior.
-
-* The following variables are no longer exported from GDK. (Other variables
- are also no longer exported; the following are the ones found used
- externally in a large sample of GTK+ code.)
-
- Variable Replacement
- ======== ===========
- gdk_null_window_warnings None - did nothing in GTK+-1.2.
- gdk_leader_window None - private variable
- gdk_screen gdk_x11_get_default_screen ()
- gdk_root_window gdk_x11_get_default_root_xwindow ()
- gdk_root_parent gdk_get_default_root_window ()
- gdk_error_code/gdk_error_warnings gdk_error_trap_push()/pop()
- gdk_display_name gdk_get_display ()
- gdk_wm_delete_window gdk_atom_intern ("WM_DELETE_WINDOW", FALSE)
- gdk_wm_take_focus gdk_atom_intern ("WM_TAKE_FOCUS", FALSE)
- gdk_wm_protocols gdk_atom_intern ("WM_PROTOCOLS", FALSE)
-
-* The handling of Colormaps and widgets has been changed:
-
- - The default colormap for widgets is now the GdkRGB colormap, not
- the system default colormap. If you try to use resources created for
- a widget (e.g., widget->style) with a window using the system
- colormap, errors will result on some machines.
-
- - gtk_widget_push/pop_colormap() only cause the colormap to be
- explicitely set on toplevel widgets not on all widgets. The
- colormap for other widgets (when not set using
- gtk_widget_set_colormap()), is determined by finding the nearest
- ancestor with a colormap set on it explicitely, or if that
- fails, the default colormap.
-
-* The default selected day for GtkCalendar is now the current day in the
- month, not the first day in the month. The current month and year
- were already used.
-
-* GDK is no longer put into threaded mode automatically when
- g_thread_init() has been called. In order to use the
- global GDK thread mutex with gdk_threads_enter() and
- gdk_threads_leave(), you must call gdk_threads_init() explicitely.
-
- If you aren't using GDK and GTK+ functions from multiple threads,
- there is no reason to call gdk_threads_init().
-
-* The GtkPreviewInfo struct has had its visual and colormap fields
- removed. Also, gtk_preview_get_cmap() and gtk_preview_get_visual()
- are deprecated, as GdkRgb works on any colormap and visual. You no
- longer need to gtk_widget_push_cmap (gtk_preview_get_cmap ()) in
- your code.
-
-* The GtkBox, GtkTable, and GtkAlignment widgets now call
- gtk_widget_set_redraw_on_allocate (widget, FALSE); on themselves.
- If you want to actually draw contents in a widget derived from
- one of these widgets, you'll probably want to change this
- in your init() function.
-
-* A number of widgets are now NO_WINDOW widgets (most importantly
- GtkButton, but also GtkRange and GtkNotebook)
-
- This has a couple of effects:
-
- - If you are deriving from one of these widgets, you need to
- adapt your code appropriately -- for instance, drawing coordinates
- start from widget->allocation.x, widget->allocation.y.
-
- - If you are embedding one of these widgets in a custom widget,
- you must make sure you call gtk_container_propagate_expose()
- correctly, as you must for any NO_WINDOW widgets.
-
- GtkFixed is a little special; it is now created by default as
- a NO_WINDOW widget, but if you do
-
- gtk_fixed_set_has_window (fixed, TRUE);
-
- after creating a fixed widget, it will create a window and
- handle it properly.
-
-* GtkLayout no longer has the xoffset, yoffset fields, which used
- to store the difference between world and window coordinates for
- layout->bin_window. These coordinate systems are now always
- the same.
-
-* gtk_paint_focus(), gtk_draw_focus() and GtkStyle::draw_focus()
- have been changed a bit:
-
- - A GtkStateType argument has been added to gtk_paint_focus()
- - The default implementation of GtkStyle::draw_focus virtual
- function now draws a focus rectangle whose width is
- determinted by the GtkWidget::focus-width style property.
- - The rectangle passed in is the bounding box, instead of
- the rectangle used in the gdk_draw_rectangle() call, so it is
- no longer necessary to subtract 1 from the width and height.

-DON'T EDIT THIS FILE - changes are now maintained in the reference
-manual, see docs/reference/gtk/changes-*.sgml. Also, when adding a
-change to the manual, you should amend the docs for all
-newly-deprecated features to point to the replacement for that
-feature, and be sure the GTK_DISABLE_DEPRECATED guards are in place in
-the header files. Be sure to add a note to the docs for EACH
-deprecated function; don't just do the changes-*.sgml change.
