ParamSpecFloatProtocol

public protocol ParamSpecFloatProtocol : ParamSpecProtocol

The ParamSpecFloatProtocol protocol exposes the methods and properties of an underlying GParamSpecFloat 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 ParamSpecFloat. Alternatively, use ParamSpecFloatRef 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 float properties.

  • ptr

    Untyped pointer to the underlying GParamSpecFloat instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer { get }
  • param_spec_float_ptr Default implementation

    Typed pointer to the underlying GParamSpecFloat instance.

    Default Implementation

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

    Declaration

    Swift

    var param_spec_float_ptr: UnsafeMutablePointer<GParamSpecFloat> { get }

ParamSpecFloat Class: ParamSpecFloatProtocol 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: Float { get }
  • maximum Extension method

    maximum value for the property specified

    Declaration

    Swift

    var maximum: Float { get }
  • defaultValue Extension method

    default value for the property specified

    Declaration

    Swift

    var defaultValue: Float { get }
  • epsilon Extension method

    values closer than epsilon will be considered identical by g_param_values_cmp(); the default value is 1e-30.

    Declaration

    Swift

    var epsilon: Float { get }
