/// Example:
///
/// **Note**: On platforms that support scrolling [phases](phase())
/// , the delta may be null when:
/// * scrolling is about to begin, but the distance did not yet change (Qt::ScrollBegin),
/// * or scrolling has ended and the distance did not change anymore (Qt::ScrollEnd).
/// **Note**: On X11 this value is driver specific and unreliable, use angleDelta() instead
