ConstraintTargetProtocol

public protocol ConstraintTargetProtocol

The GtkConstraintTarget interface is implemented by objects that can be used as source or target in GtkConstraints.

Besides GtkWidget, it is also implemented by GtkConstraintGuide.

The ConstraintTargetProtocol protocol exposes the methods and properties of an underlying GtkConstraintTarget 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 ConstraintTarget. Alternatively, use ConstraintTargetRef as a lighweight, unowned reference if you already have an instance you just want to use.
