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