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 with * gtk_settings_set_string_property(), gtk_settings_set_long_property(), * etc. 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. */ #define DEFAULT_TIMEOUT_INITIAL 500 #define DEFAULT_TIMEOUT_REPEAT 50 #define DEFAULT_TIMEOUT_EXPAND 500 typedef struct _GtkSettingsPropertyValue GtkSettingsPropertyValue;
