highlightPlaybackRange

since 1.8.0

Description

Places the highlight markers at the specified start and end-beat range. Unlike actually setting playbackRange this method only places the selection markers without actually changing the playback range. This method can be used when building custom selection systems (e.g. having draggable handles).

JavaScript

highlightPlaybackRange(startBeat: Beat, endBeat: Beat): void

C#

void HighlightPlaybackRange(Beat startBeat, Beat endBeat)

Kotlin

fun highlightPlaybackRange(startBeat: Beat, endBeat: Beat): Unit

Parameter	Summary
