ParamSpecExpressionRef

public struct ParamSpecExpressionRef : ParamSpecExpressionProtocol

A GParamSpec for properties holding a GtkExpression.

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

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

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

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!
