pub fn gnome_layout(value: &str) -> Option<ButtonLayout>Expand description
A button-layout as GNOME writes it, bare or as gsettings prints it
(‘appmenu:minimize,maximize,close’): the left side’s buttons before the
colon, the right’s after it; without a colon, all on the left, as GNOME
reads it. “appmenu”, “menu”, “icon” and “spacer” have no place in Sioul’s
bar. None for an empty value.
