creating graphical user interfaces. Offering a complete set of widgets,
GTK+ is suitable for projects ranging from small one-off projects to
complete application suites.
See the file 'INSTALL'
+Release notes for 2.14
+======================
+
+* gtkitemfactory.h is now completely deprecated.
+ As gtkactiongroup.h and gtkstock.h no longer include the gtkitemfactory.h
+ header, this might break application using gtk_item_factory_* symbols
+ without including gtkitemfactory.h - even though this behaviour has never
+ been supported in the first place.
+
+* The GtkFileSystem semi-private interface has been removed.
+ The GTK+ filechooser implementation now uses GIO directly, which has
+ rendered external filesystem implementations unnecessary. Consequently,
+ the GtkFileSystem interface is no longer available, nor the filechooser
+ will load any GtkFileSystem implementation.
+
+* GtkComboBox now renders the popdown button insensitive when
+ the model is empty. Applications which want to populate the list
+ only before displaying it can set gtk_combo_box_set_button_sensitivity
+ to GTK_SENSITIVITY_ON, so that the button is always sensitive or
+ GTK_SENSITIVITY_OFF to make it insensitive respectively.
+
+* GtkAdjustment now enforces that values are restricted to the
+ range [lower, upper - page_size]. This has always been the documented
+ behaviour, and the recommended practice is to set page_size to 0
+ when using adjustments for simple scalar values, like in a slider
+ or spin button.
+
+* gdk-pixbuf will use GIO for mime type detection if possible. For
+ this to work, shared-mime-info needs to be installed and XDG_DATA_DIRS
+ set accordingly at configure time. Otherwise, gdk-pixbuf falls
+ back to its built-in sniffing implementation.
+
+Release notes for 2.12
+======================
+
+* gtk_about_dialog_get/set_name() were deprecated in favour of
+ gtk_about_dialog_get/set_program_name(), the GtkAboutDialog now uses the
+ "program-name" property instead of the conflicting "name" property.
+
+* The gdk-pixbuf tiff loader now requires libtiff 3.6.0 or later.
+
+* Support for Windows 9x/ME has officially been removed. It hasn't worked
+ since 2.6 anyway.
+
+* The GtkTextBufferTargetInfo enumeration values have been changed from
+ G_MAXUINT-0, G_MAXUINT-1, G_MAXUINT-2, etc, to -1, -2, -3 to stay within
+ ANSI C limits.
+
+* A change in the handling of _NET_WM_USER_TIME properties on toplevel
+ windows can cause deadlock problems with window managers that are using
+ GDK for drawing decorations. In particular, metacity <= 2.18.0 is affected
+ by this. The problem has been fixed in metacity 2.18.1.
+
+* Semi-private GtkTextLayout api has changed: new GtkTextLayout method
+ invalidate_cursors(), and new functions gtk_text_layout_invalidate_cursors()
+ and gtk_text_layout_cursors_changed(), which should be used in place of
+ gtk_text_layout_invalidate() and gtk_text_layout_changed() if invalidation
+ is due to marks moved or changed selection; new GtkTextLineDisplay structure
+ member. Source compatibility is preserved; binary compatibility may break
+ only if GtkTextLineDisplay structure was created on stack or as a part
+ of another structure (in particular GnomeCanvas and its clones do not need
+ recompiling).
+
+* Another new signal has been added to GtkNotebook. The new signal
+ is called create-window, so this name can no longer be used for signals
+ in objects derived from GtkNotebook.
+
+* The gtk_notebook_set/get_group_id() functions were found to be insufficient
+ and have been deprecated in favour of gtk_notebook_set/get_group().
+
+* The move-focus signal has been moved to GtkWidget, to unify the
+ various implementations of this signal in specific widgets. Great care
+ has been taken to make sure that all code using this signal continues
+ to work.
+
+* An unused and hardly visible GtkFrame has been removed from the menu
+ widget hierarchy when GtkComboBox::appears-as-list style property is
+ set. Any RC file applying a different style to any widget below the
+ widget path "gtk-combobox-popup-window.GtkFrame" should take into
+ account that the frame no longer exists.
+
+* The external print preview application used by GtkPrintOperationPreview
+ is now passed the print settings on the command line with the
+ --print-settings parameter pointing to a temp file containing the
+ settings. The preview application assumes ownership of the file and
+ should delete it once it does not need it anymore. The --print-settings
+ commandline option is understood by Evince 0.9.0 and newer. To use a
+ different print preview application, change the gtk-print-preview-command
+ setting in your gtkrc file, e.g. gtk-print-preview-command = "ggv %f"
+
+* GtkMenuShell is now defined as an abstract type. It was already
+ documented as an abstract class, and there is little reason to
+ instantiate it.
+
+* The GtkTooltips struct (this is the old tooltips API) is now considered
+ private. Code that used to access this struct, in particular the
+ tips_data_list field, will need to change. All of the old tooltips
+ API has been deprecated in favour of a new implementation and
+ API. This affects all of the gtk_tooltips_ functions, and functions
+ which take a GtkTooltips argument, such as gtk_tool_item_set_tooltip()
+ and gtk_menu_tool_button_set_arrow_tooltip().
+
+* The memory management of the GtkRecentManager object has been changed,
+ as using the screen didn't guarantee that the singleton instance was
+ correctly destroyed. The screen-related functions have been deprecated,
+ and should not be used anymore; the GtkRecentManager instance returned by
+ the gtk_recent_manager_get_default() function is guaranteed to be valid
+ for the entire lifetime of an application.
+
+* A number of interfaces that have been superseded by newer interfaces for
+ a long time have finally been deprecated. This includes
+ gtk_widget_ref/unref(), gtk_rc_style_ref/unref() and the old file selector.
+
+* The various coordinate systems in use in GtkTreeView widgets have
+ been clarified in the documentation, and in the cause of doing so,
+ the functions gtk_tree_view_widget_to_tree_coords() and
+ gtk_tree_view_tree_to_widget_coords() have been deprecated in
+ favour of a new family of gtk_tree_view_convert_ functions.
+
+* gtk_menu_item_remove_submenu() has been deprecated in favour of
+ gtk_menu_item_set_submenu (..., NULL).
+
+* gtk_default_draw_check() has been fixed to really decrease the
+ indicator size by one pixel to ensure an odd size instead of
+ accidentially increasing it.
+ Consequently, gtk_cell_renderer_toggle_render() could be fixed to
+ not subtract 1 from the size passed to gtk_paint_option(), which
+ was just a workaround for above off-by-two for even sizes (theme
+ engines now get the real indicator size passed).
+ The default toggle size of GtkCheckMenuItem and GtkCellRendererToggle
+ has been changed to 13 to be consistent with GtkCheckButton.
+ The only visible change with default settings is that the indicator in
+ GtkCellRendererToggle has changed its size from 11 to 13 and is now
+ consistent with menus and toggle buttons.
+
+* GTK+ has always required that gtk_init() (or a variant thereof) is
+ called before any other GTK+ function. Some applications call functions
+ like gtk_clipboard_get() to check if they need to call gtk_init(),
+ anyway. A change in GLib 2.14 has recently broken this unsupported
+ practise. It is worth pointing out that calling gtk_init() twice
+ does no harm.
