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 DConf.

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().
