A clutter.Score
allows you to start and stop several timelines at once, or run them in sequence one after the other.
To add a timeline that should start first, call score.append()
with None for the parent argument.
All such timelines will be started when you call score.start()
.
To add a timeline that should be started when a previously added timeline stops, call score.append()
with the first
timeline for the parent argument.
