ConstraintTargetRef Structure Reference
ConstraintTargetRef
public struct ConstraintTargetRef : ConstraintTargetProtocolThe 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 ConstraintTargetRef type acts as a lightweight Swift reference to an underlying GtkConstraintTarget instance.
It exposes methods that can operate on this data type through ConstraintTargetProtocol conformance.
Use ConstraintTargetRef only as an unowned reference to an existing GtkConstraintTarget instance.
-
Untyped pointer to the underlying `GtkConstraintTarget` instance.For type-safe access, use the generated, typed pointer
constraint_target_ptrproperty instead.Declaration
