Animation Accessors

Animation accessors (class ) are a category of the Display accessors that change the appearance of an object periodically. Animation accessors hold a value of a Boolean type indicating whether the animation is on.

For efficiency reasons, the Animation accessors do not reevaluate their attributes at each count of the timer. Thus, if you change one of the attributes of the accessor, you must reassign the value to itself to force an update of the parameters, using the Assign accessor for instance. See the pump prototype in the samples library for an example.

The different Animation accessors are described as follows:

• Blink

• Invert

• Rotate
