Function gtk::source · [−]
pub fn locale_direction() -> TextDirection
Get the direction of the current locale. This is the expected reading direction for text and UI.
This function depends on the current locale being set with
setlocale() and will default to setting the
TextDirection::None will never be returned.
GTK+ sets the default text direction according to the locale
gtk_init(), and you should normally use
to obtain the current direcion.
This function is only needed rare cases when the locale is changed after GTK+ has already been initialized. In this case, you can use it to update the default text direction as follows:
⚠️ The following code is in C ⚠️
setlocale (LC_ALL, new_locale); direction = gtk_get_locale_direction (); gtk_widget_set_default_direction (direction);
