ViewportClassProtocol

public protocol ViewportClassProtocol

The ViewportClassProtocol protocol exposes the methods and properties of an underlying GtkViewportClass instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see ViewportClass. Alternatively, use ViewportClassRef as a lighweight, unowned reference if you already have an instance you just want to use.
