-- | Same as 'gtkButtonLayout', but 'gtkButtonLayoutWithSecondary' supports /primary/ and /secondary/ widget networks. 
-- The primary network is allocated the most prominent portion of the button layout, while the secondary network 
-- is alloted lesser valued space. Both the primary and the secondary widget networks can contain zero or more buttons 
-- or other widgets.
