KvadrantMessageBox
fun KvadrantMessageBox(visible: Boolean, title: String, message: String, onConfirm: () -> Unit, modifier: Modifier = Modifier, onCancel: () -> Unit? = null, confirmText: String = "ok", cancelText: String = "cancel", win8ButtonOrder: Boolean = false, cyrillic: FontFamily? = null, dismissOnOutsideClick: Boolean = false)
The phone's message box: a full-width band across the top of the screen, not a floating card.
The positive action is on the left. That is the opposite of Material, and of Windows 8, and it is not a mistake to be tidied up — it is what the phone did, and a user who reaches for the left-hand button expects it to be the one that proceeds. win8ButtonOrder flips it for anyone building the desktop profile.
Only OK and OK/Cancel exist. The phone had no others.
