CallbackActionClassRef

public struct CallbackActionClassRef : CallbackActionClassProtocol

The CallbackActionClassRef type acts as a lightweight Swift reference to an underlying GtkCallbackActionClass instance. It exposes methods that can operate on this data type through CallbackActionClassProtocol conformance. Use CallbackActionClassRef only as an unowned reference to an existing GtkCallbackActionClass instance.

  • ptr
    Untyped pointer to the underlying `GtkCallbackActionClass` instance.
    

    For type-safe access, use the generated, typed pointer _ptr property instead.
