PulseAnimation Client Reference

The PulseAnimation fades an element in and our repeatedly to create a pulsating effect. The iterations determines how many pulses there will be (which defaults to three, but it will repeat infinitely if given zero or less). The duration property defines the duration of each fade in or fade out, not the duration of the animation as a whole.

PulseAnimation Client Properties

NameDescription
animationsArray of child animations to be played (there are no assumptions placed on order because it will matter for some derived animations like , but not for others like ). To manipulate the child animations, use the functions add, clear, remove, and removeAt.
durationLength of the animation in seconds. The default is 1.
eventsThe collection of event handlers for this behavior. This property should only be used by derived behaviors and should not be publicly called by other code.
forceLayoutInIEWhether or not we should force a layout to be created for Internet Explorer by giving it a width and setting its background color (the latter is required in case the user has ClearType enabled). The default value is true. This is obviously ignored when working in other browsers.
fpsNumber of steps per second. The default is 25.
id
isActivetrue if animation is active, false if not.
isInfinitetrue if this animation will repeat forever, false otherwise.
isInitialized
isPlayingtrue if animation is playing, false if not.
isUpdating
iterationsNumber of times to repeatedly play the sequence. If zero or less iterations are specified, the sequence will repeat forever. The default value is 1 iteration.
maximumOpacityMaximum opacity to use when fading in or out. Its value can range from between 0 to 1. The default value is 1.
minimumOpacityMinimum opacity to use when fading in or out. Its value can range from between 0 to 1. The default value is 0.
percentCompletePercentage of the animation already played.
target

PulseAnimation Client Methods

NameDescription
add Add an animation as a child of this animation.
beginUpdate
clear Clear the array of child animations.
dispose Dispose the animation
endUpdate
getAnimatedValue Determine the state of the animation after the given percentage of its duration has elapsed
initialize Initialize the parent along with any child animations that have not yet been initialized themselves
interpolate The interpolate function is used to find the appropriate value between starting and ending values given the current percentage.
onEnd The onEnd method is called just after the animation is played each time.
onStart The onStart method is called just before the animation is played each time
onStep Raises an invalid operation exception because this will only be called if a SequenceAnimation has been nested inside an (or a derived type).
pause Pause the animation if it is playing. Calling play will resume where the animation left off.
play Play the sequence of animations from the beginning or where it was left off when paused
play Create an animation, play it immediately, and dispose it when finished.
raiseEnded Raise the ended event
raisePropertyChangedRaises a change notification event.
raiseStarted Raise the started event
raiseStep Raise the step event
remove Remove the animation from the array of child animations.
removeAt Remove the animation at a given index from the array of child animations.
setOwner Make this animation the child of another animation
setValue Set the current state of the animation
stop Stop playing the entire sequence of animations
