public struct ParamSpecDoubleRef : ParamSpecDoubleProtocol

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

A GParamSpec derived structure that contains the meta data for double properties.

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

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