    The first example above simulates clicking the \c escape key on \c
    myWidget without any keyboard modifiers and without delay. The
    second example simulates clicking \c shift-escape on \c myWidget
    with a following 200 ms delay of the test.

    well as a \a delay (in milliseconds) of the test before each key
    click.

    Example:

    a \a delay (in milliseconds) is given, the test will wait before
    moving the mouse pointer.

/*!
    \fn char *QTest::toString(const T &value)

    Returns a textual representation of \a value. This function is used by
    \l QCOMPARE() to output verbose information in case of a test failure.

    You can add specializations of this function to your test to enable
    verbose output.

    \bold {Note:} The caller of toString() must delete the returned data
    using \c{delete[]}.  Your implementation should return a string
    created with \c{new[]} or qstrdup().

    Example:

    \code
    namespace QTest {
        template<>
        char *toString(const MyPoint &point)
        {
            QByteArray ba = "MyPoint(";
            ba += QByteArray::number(point.x()) + ", " + QByteArray::number(point.y());
            ba += ")";
            return qstrdup(ba.data());
        }
    }
    \endcode

    The example above defines a toString() specialization for a class
    called \c MyPoint. Whenever a comparison of two instances of \c
    MyPoint fails, \l QCOMPARE() will call this function to output the
    contents of \c MyPoint to the test log.

/*! \fn void QTest::qWait(int ms)

    Waits for \a ms milliseconds. While waiting, events will be processed and

    int i = 0;
    while (myNetworkServerNotResponding() && i++ < 50)
