    \class Q3DateTimeEdit q3datetimeedit.h
    \brief The Q3DateTimeEdit class combines a Q3DateEdit and Q3TimeEdit
    widget into a single widget for editing datetimes.

    \compat

    Q3DateTimeEdit consists of a Q3DateEdit and Q3TimeEdit widget placed
    side by side and offers the functionality of both. The user can
    edit the date and time by using the keyboard or the arrow keys to
    increase/decrease date or time values. The Tab key can be used to
    move from section to section within the Q3DateTimeEdit widget, and
    the user can be moved automatically when they complete a section
    using setAutoAdvance(). The datetime can be set with
    setDateTime().

    The date format is read from the system's locale settings. It is
    set to year, month, day order if that is not possible. See
    Q3DateEdit::setOrder() to change this. Times appear in the order
    hours, minutes, seconds using the 24 hour clock.

    It is recommended that the Q3DateTimeEdit is initialised with a
    datetime, e.g.
    \code
    Q3DateTimeEdit *dateTimeEdit = new Q3DateTimeEdit(QDateTime::currentDateTime(), this);
    dateTimeEdit->dateEdit()->setRange(QDateTime::currentDate(),
                                        QDateTime::currentDate().addDays(7));
    \endcode
    Here we've create
