PropertyExpressionProtocol

public protocol PropertyExpressionProtocol : ExpressionProtocol

A GObject property value in a GtkExpression.

The PropertyExpressionProtocol protocol exposes the methods and properties of an underlying GtkPropertyExpression 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 PropertyExpression. Alternatively, use PropertyExpressionRef as a lighweight, unowned reference if you already have an instance you just want to use.
