ParamSpecDoubleProtocol

public protocol ParamSpecDoubleProtocol : ParamSpecProtocol

The ParamSpecDoubleProtocol protocol exposes the methods and properties of an underlying GParamSpecDouble 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 ParamSpecDouble. Alternatively, use ParamSpecDoubleRef as a lighweight, unowned reference if you already have an instance you just want to use.

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

  • ptr

    Untyped pointer to the underlying GParamSpecDouble instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer { get }
  • param_spec_double_ptr Default implementation

    Typed pointer to the underlying GParamSpecDouble instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GParamSpecDouble instance.

    Declaration

    Swift

    var param_spec_double_ptr: UnsafeMutablePointer<GParamSpecDouble> { get }

ParamSpecDouble Class: ParamSpecDoubleProtocol extension (methods and fields)

  • parentInstance Extension method

    private GParamSpec portion

    Declaration

    Swift

    var parentInstance: GParamSpec { get }
  • minimum Extension method

    minimum value for the property specified

    Declaration

    Swift

    var minimum: Double { get }
  • maximum Extension method

    maximum value for the property specified

    Declaration

    Swift

    var maximum: Double { get }
  • defaultValue Extension method

    default value for the property specified

    Declaration

    Swift

    var defaultValue: Double { get }
  • epsilon Extension method

    values closer than epsilon will be considered identical by g_param_values_cmp(); the default value is 1e-90.

    Declaration

    Swift

    var epsilon: Double { get }
