Qt5 QAccessibleWidget Example wrong usage of QAccessible::updateAccessibility

http://qt-project.org/doc/qt-5/accessible-qwidget.html#qaccessiblewidget-example

void QAbstractSlider::setValue(int value)
{
...
QAccessible::updateAccessibility(this, 0, QAccessible::ValueChanged);
...
}

QAccessible::updateAccessibility refers to Qt 4.8 implementation and not Qt 5.

Should be something like this:
void QAbstractSlider::setValue(int value)
{
....
QAccessibleValueChangeEvent event(this, d->value);
QAccessible::updateAccessibility(&event;);
....
}
