Class
GtkSettings
Description [src]
final class Gtk.Settings : GObject.Object
implements Gtk.StyleProvider {
/* No available fields */
}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().
Functions
gtk_settings_get_default
Gets the GtkSettings object for the default display, creating
it if necessary.
Instance methods
gtk_settings_reset_property
Undoes the effect of calling g_object_set() to install an
application-specific value for a setting.
