### Detailed Description

GtkSettings provide a mechanism to share global settings between applications. On the X window system, this sharing is realized by an XSettings (\emph{undocumented}) manager that is usually part of the desktop environment, along with utilities that let the user change these settings. In the absence of an Xsettings manager, settings can also be specified in RC files.

Applications can override system-wide settings with `gtkSettingsSetStringProperty`, `gtkSettingsSetLongProperty`, etc. This should be restricted to special cases though; GtkSettings are not meant as an application configuration facility. When doing so, you need to be aware that settings that are specific to individual widgets may not be available before the widget type has been realized at least once. The following example demonstrates a way to do this:

      gtk_init (&argc, &argv);
      /* make sure the type is realized */
      g_type_class_unref (g_type_class_ref (GTK_TYPE_IMAGE_MENU_ITEM));
      g_object_set (gtk_settings_get_default (), "gtk-menu-images", FALSE, NULL);

There is one GtkSettings instance per screen. It can be obtained with `gtkSettingsGetForScreen`, but in many cases, it is more convenient to use `gtkWidgetGetSettings`. `gtkSettingsGetDefault` returns the GtkSettings instance for the default screen.

### Properties

`color-hash` [GHashTable : * : Read]

  Holds a hash table representation of the `"gtk-color-scheme"` setting, mapping color names to `GdkColor`s. Since 2.10

`gtk-alternative-button-order` [logical : Read / Write]

  Whether buttons in dialogs should use the alternative button order. Default value: FALSE

`gtk-alternative-sort-arrows` [logical : Read / Write]

  Controls the direction of the sort indicators in sorted list and tree views. By default an arrow pointing down means the column is sorted in ascending order. When set to `TRUE`, this order will be inverted. Default value: FALSE Since 2.12

`gtk-auto-mnemonics` [logical : Read / Write]

  Whether mnemonics should be automatically shown and hidden when the user presses the mnemonic activator. Default value: FALSE Since 2.20

`gtk-button-images` [logical : Read / Write]

  Whether images should be shown on buttons. Default value: TRUE

`gtk-can-change-accels` [logical : Read / Write]

  Whether menu accelerators can be changed by pressing a key over the menu item. Default value: FALSE

`gtk-color-palette` [character : * : Read / Write]

  Palette to use in the color selector. Default value: "black:white:gray50:red:purple:blue:light blue:green:yellow:orange:lavender:brown:goldenrod4:dodger blue:pink:light green:gray10:gray30:gray75:gray90"

      name2: color2
      ...

  Color names must be acceptable as identifiers in the gtkrc syntax, and color specifications must be in the format accepted by `gdkColorParse`.

  Note that due to the way the color tables from different sources are merged, color specifications will be converted to hexadecimal form when getting this property.

  Starting with GTK+ 2.12, the entries can alternatively be separated by ';' instead of newlines:

      name1: color1; name2: color2; ...

  Default value: "" Since 2.10
