    Returns \c true if \l {QQuickItem::}{updatePolish()} has not been called
    on \a item since the last call to \l {QQuickItem::}{polish()},
    otherwise returns \c false.

    When assigning values to properties in QML, any layouting the item
    must do as a result of the assignment might not take effect immediately,
    but can instead be postponed until the item is polished. For these cases,
    you can use this function to ensure that the item has been polished
    before the execution of the test continues. For example:

    \code
        QVERIFY(QQuickTest::qIsPolishScheduled(item));
        QVERIFY(QQuickTest::qWaitForItemPolished(item));
    \endcode

    Without the call to \c qIsPolishScheduled() above, the
    call to \c qWaitForItemPolished() might see that no polish
    was scheduled and therefore pass instantly, assuming that
    the item had already been polished. This function
    makes it obvious why an item wasn't polished and allows tests to
    fail early under such circumstances.

    The QML equivalent of this function is
    \l {TestCase::}{isPolishScheduled()}.

    \sa QQuickItem::polish(), QQuickItem::updatePolish()

/*!

    Waits for \a timeout milliseconds or until
    \l {QQuickItem::}{updatePolish()} has been called on \a item.

    Returns \c true if \c updatePolish() was called on \a item within

    The QML equivalent of this function is
    \l {TestCase::}{waitForItemPolished()}.
