ProgressBarAccessibleClassProtocol

public protocol ProgressBarAccessibleClassProtocol

The ProgressBarAccessibleClassProtocol protocol exposes the methods and properties of an underlying GtkProgressBarAccessibleClass 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 ProgressBarAccessibleClass. Alternatively, use ProgressBarAccessibleClassRef as a lighweight, unowned reference if you already have an instance you just want to use.
