### Class

# GtkSettings

#### Description [src]

    final class Gtk.Settings : GObject.Object
      implements Gtk.StyleProvider {
      /* No available fields */
    }

`GtkSettings` provides 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.

On Wayland, the settings are obtained either via a settings portal, or by reading desktop settings from `GSettings`.

On macOS, the settings are obtained from `NSUserDefaults`.

In the absence of these sharing mechanisms, GTK reads default values for settings from `settings.ini` files in `/etc/gtk-4.0`, `$XDG_CONFIG_DIRS/gtk-4.0` and `$XDG_CONFIG_HOME/gtk-4.0`. These files must be valid key files (see `GKeyFile`), 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 g_object_set(). This should be restricted to special cases though; `GtkSettings` are not meant as an application configuration facility.

There is one `GtkSettings` instance per display. It can be obtained with `gtk_settings_get_for_display()`, but in many cases, it is more convenient to use `gtk_widget_get_settings()`.
