@param rEndEvent

Event to be fired, when the activity ends.

@param rEventQueue
|
|
Queue to add end event to
|
|
|
|
@param nMinDuration
|
|
Minimal duration of the activity (might actually be
|
|
longer because of nMinNumberOfFrames). Note that this
|
|
duration must always be the <em>simple</em> duration,
|
|
i.e. without any repeat.
|
|
|
|
@param rRepeats
|
|
Number of repeats. If this parameter is invalid,
|
|
infinite repeat is assumed.
|
|
|
|
@param nAccelerationFraction
|
|
Value between 0 and 1, denoting the fraction of the
|
|
total simple duration, which the animation should
|
|
accelerate.
|
|
|
|
@param nDecelerationFraction
|
|
Value between 0 and 1, denoting the fraction of the
|
|
total simple duration, which the animation should
|
|
decelerate. Note that the ranges
|
|
[0,nAccelerationFraction] and
|
|
[nDecelerationFraction,1] must be non-overlapping!
|
|
|
|
@param bAutoReverse
|
|
When true, at the end of the simple duration, the
|
|
animation plays reversed to the start value. Note that
|
|
nMinDuration still specifies the simple duration,
|
|
i.e. when bAutoReverse is true, the implicit duration
|
|
doubles.
