Description:

public class Settings : Object, StyleProvider

GtkSettings provide a mechanism to share global settings between applications.

On the X window system, this sharing is realized by an XSettings 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, GTK+ reads default values for settings from `settings.ini` files in `/etc/gtk-3.0`, `$XDG_CONFIG_DIRS/gtk-3.0` and `$XDG_CONFIG_HOME/gtk-3.0`. These files must be valid key files (see KeyFile), and have a section called Settings. Themes can also provide default values for settings by installing a `settings.ini` file next to their `gtk.css` file.

Applications can override system-wide settings by setting the property of the GtkSettings object with @set. 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-enable-animations", FALSE, NULL);

There is one GtkSettings instance per screen. It can be obtained with get_for_screen, but in many cases, it is more convenient to use get_settings. get_default returns the GtkSettings instance for the default screen.
