Class
GtkSettings
Description [src]
class Gtk.Settings : GObject.Object
implements Gtk.StyleProvider {
/* No available fields */
}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 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. 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
gtk_settings_get_for_screen(), but in many cases, it is more convenient
to use gtk_widget_get_settings(). gtk_settings_get_default() returns the
GtkSettings instance for the default screen.
Functions
gtk_settings_get_default
Gets the GtkSettings object for the default GDK screen, creating
it if necessary. See gtk_settings_get_for_screen().
gtk_settings_get_for_screen
Gets the GtkSettings object for screen, 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. After this call,
the setting will again follow the session-wide value for
this setting.
