/// Focus events are sent to widgets when the keyboard input focus
/// changes. Focus events occur due to mouse actions, key presses
/// (such as **{Tab}** or **{Backtab}),** the window system, popup
/// menus, keyboard shortcuts, or other application-specific reasons.
/// The reason for a particular focus event is returned by reason()
/// in the appropriate event handler.
///
/// The event handlers QWidget::focusInEvent(),
/// QWidget::focusOutEvent(), QGraphicsItem::focusInEvent and
/// QGraphicsItem::focusOutEvent() receive focus events.
