SpinButtonAccessibleClassProtocol

public protocol SpinButtonAccessibleClassProtocol

The SpinButtonAccessibleClassProtocol protocol exposes the methods and properties of an underlying GtkSpinButtonAccessibleClass 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 SpinButtonAccessibleClass. Alternatively, use SpinButtonAccessibleClassRef as a lighweight, unowned reference if you already have an instance you just want to use.
