*** ** * ** ***

A PlaybackTransportRowPresenter renders a `https://developer.android.com/reference/kotlin/androidx/leanback/widget/PlaybackControlsRow` to display a series of playback control buttons. Typically this row will be the first row in a fragment such as the `https://developer.android.com/reference/kotlin/androidx/leanback/app/PlaybackSupportFragment`.

The detailed description is rendered using a `https://developer.android.com/reference/kotlin/androidx/leanback/widget/Presenter` passed in `https://developer.android.com/reference/kotlin/androidx/leanback/widget/PlaybackTransportRowPresenter#setDescriptionPresenter(androidx.leanback.widget.Presenter)`. This can be an instance of `https://developer.android.com/reference/kotlin/androidx/leanback/widget/AbstractDetailsDescriptionPresenter`. The application can access the detailed description ViewHolder from `https://developer.android.com/reference/kotlin/androidx/leanback/widget/PlaybackTransportRowPresenter.ViewHolder#getDescriptionViewHolder()`.
