GetHeight()

)

const

Returns

height of the track as it now appears, expanded or collapsed

Total "height" of channels of a track includes padding areas above and below it, and is pixel-accurate for the channel group. The "heights" of channels within a group determine the proportions of heights of the track data shown – but the actual total pixel heights may differ when other fixed-height adornments and paddings are added, according to other rules for allocation of height.
