  Public Functions

  `ViewerPropertyHandler`(PropertySet *propSet)

    Creates a viewer property handler from a given property set propSet.

  Variant `propertyValue`(PropertyKey key) const

    Returns the property value for the specified property key.

    Returns an empty Variant if the property key was not found.

  void `setPropertyValue`(PropertyKey key, Variant data)

    Sets the property key and value to this handlers property set.

    If key exists in the property set, the paired property value is updated to data. Otherwise the key/value pair is added to the property set.

  double `defaultFramesPerSecond`() const

    Returns the frames per second for the animation.

  void `setDefaultFramesPerSecond`(double animationFPS)

    Sets the frames per second for the animation.

  int `firstFrameDelay`() const

    Returns the first frame delay in milliseconds.

  void `setFirstFrameDelay`(int milliSeconds)

    Sets the first frame delay in milliseconds.

  int `lastFrameDelay`() const

    Returns the last frame delay in milliseconds.

  void `setLastFrameDelay`(int milliSeconds)

    Sets the last frame delay in milliseconds.

  int `numberOfParticleTraceAnimationSteps`() const

    Returns the number of steps to use for the particle trace animation.

  void `setNumberOfParticleTraceAnimationSteps`(int numAnimationSteps)

    Sets the number of steps to use for particle trace animation.

  bool `hasStartAnimation`() const

    Returns the flag that controls automatic start of the animation, if any.

  void `setStartAnimation`(bool start)

    Sets the flag that controls automatic start of the animation, if any.

  Color3f `haloColor`() const

    Returns the color of halos used in the viewer, e.g to highlight parts.

  void `setHaloColor`(const Color3f &color)

    Sets the color of halos used in the viewer, e.g to highlight parts.

  int `animatedCuttingPlaneIndex`() const

    Returns the index of the cutting plane to animate.

  void `setAnimatedCuttingPlaneIndex`(int index)

    Sets the index of the cutting plane to animate.

  int `animatedCuttingPlaneNumberOfFrames`() const

    Returns the number of frames for the cutting plane animation.

  void `setAnimatedCuttingPlaneNumberOfFrames`(int numFrames)

    Sets the number of frames for the cutting plane animation.

  double `animatedCuttingPlaneDistancePerFrame`() const

    Returns the distance per frame for the cutting plane animation.

  void `setAnimatedCuttingPlaneDistancePerFrame`(double distance)

    Sets the distance per frame for the cutting plane animation.

  Str `viewTitle`() const

    Returns view title.

  void `setViewTitle`(const Str &title)

    Sets view title.

  Public Static Functions

  static Str `propertySetClassType`()

    Returns the class type of the property set.

  static bool `isValidPropertySet`(const PropertySet &propSet)

    Returns true if the specified property set is a valid viewer property set.
