  49  * @Short_description: Sharing settings between applications
  50  * @Title: Settings
  51  *
  52  * GtkSettings provide a mechanism to share global settings between
  53  * applications.
  54  *
  55  * On the X window system, this sharing is realized by an
  56  * <ulink url="http://www.freedesktop.org/wiki/Specifications/xsettings-spec">XSettings</ulink>
  57  * manager that is usually part of the desktop environment, along with
  58  * utilities that let the user change these settings. In the absence of
  59  * an Xsettings manager, GTK+ reads default values for settings from
  60  * <filename>settings.ini</filename> files in
  61  * <filename>/etc/gtk-3.0</filename> and <filename>$XDG_CONFIG_HOME/gtk-3.0</filename>. These files must be valid key files (see #GKeyFile), and have
  62  * a section called Settings. Themes can also provide default values
  63  * for settings by installing a <filename>settings.ini</filename> file
  64  * next to their <filename>gtk.css</filename> file.
  65  *
  66  * Applications can override system-wide settings with
  67  * gtk_settings_set_string_property(), gtk_settings_set_long_property(),
  68  * etc. This should be restricted to special cases though; GtkSettings are
  69  * not meant as an application configuration facility. When doing so, you
  70  * need to be aware that settings that are specific to individual widgets
  71  * may not be available before the widget type has been realized at least
  72  * once. The following example demonstrates a way to do this:
  73  * <informalexample><programlisting>
  74  *   gtk_init (&argc, &argv);
  75  *
  76  *   /&ast; make sure the type is realized &ast;/
  77  *   g_type_class_unref (g_type_class_ref (GTK_TYPE_IMAGE_MENU_ITEM));
  78  *
  79  *   g_object_set (gtk_settings_get_default (), "gtk-menu-images", FALSE, NULL);
  80  * </programlisting></informalexample>
  81  *
  82  * There is one GtkSettings instance per screen. It can be obtained with
  83  * gtk_settings_get_for_screen(), but in many cases, it is more convenient
  84  * to use gtk_widget_get_settings(). gtk_settings_get_default() returns the
  85  * GtkSettings instance for the default screen.
