ClosureExpressionProtocol

public protocol ClosureExpressionProtocol : ExpressionProtocol

An expression using a custom GClosure to compute the value from its parameters.

The ClosureExpressionProtocol protocol exposes the methods and properties of an underlying GtkClosureExpression 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 ClosureExpression. Alternatively, use ClosureExpressionRef as a lighweight, unowned reference if you already have an instance you just want to use.
