    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()

    \overload qIsPolishScheduled()

    Returns \c true if there are any items managed by this window for
    which \c qIsPolishScheduled(item) returns \c true, otherwise
    returns \c false.

    For example, if an item somewhere within the scene may or may not
    be polished, but you need to wait for it if it is, you can use
    the following code:

    \code
        if (QQuickTest::qIsPolishScheduled(window))
            QVERIFY(QQuickTest::qWaitForPolish(window));
    \endcode
