+    \ingroup advanced

+    \mainclass
+
+    TQDateEdit allows the user to edit dates by using the keyboard or
+    the arrow keys to increase/decrease date values. The arrow keys
+    can be used to move from section to section within the TQDateEdit
+    box. Dates appear in accordance with the local date/time settings
+    or in year, month, day order if the system doesn't provide this
+    information. It is recommended that the TQDateEdit be initialised
+    with a date, e.g.
+
+    \code
+    TQDateEdit *dateEdit = new TQDateEdit( TQDate::tqcurrentDate(), this );
+    dateEdit->setRange( TQDate::tqcurrentDate().addDays( -365 ),
+			TQDate::tqcurrentDate().addDays(  365 ) );
+    dateEdit->setOrder( TQDateEdit::MDY );
+    dateEdit->setAutoAdvance( TRUE );
+    \endcode
+
+    Here we've created a new TQDateEdit object initialised with today's
+    date and restricted the valid date range to today plus or minus
+    365 days. We've set the order to month, day, year. If the auto
+    advance property is TRUE (as we've set it here) when the user
+    completes a section of the date, e.g. enters two digits for the
+    month, they are automatically taken to the next section.
+
+    The maximum and minimum values for a date value in the date editor
+    default to the maximum and minimum values for a TQDate. You can
+    change this by calling setMinValue(), setMaxValue() or setRange().
+
+    Terminology: A TQDateEdit widget comprises three 'sections', one
+    each for the year, month and day. You can change the separator
+    character using TQDateTimeEditor::setSeparator(), by default the
+    separator will be taken from the systems settings. If that is
+    not possible, it defaults to "-".

+    \brief The TQTimeEdit class provides a time editor.
+
+    \ingroup advanced
+    \ingroup time
+    \mainclass
+
+    TQTimeEdit allows the user to edit times by using the keyboard or
+    the arrow keys to increase/decrease time values. The arrow keys
+    can be used to move from section to section within the TQTimeEdit
+    box. The user can automatically be moved to the next section once
+    they complete a section using setAutoAdvance(). Times appear in
+    hour, minute, second order. It is recommended that the TQTimeEdit
+    is initialised with a time, e.g.
+    \code
+    TQTime timeNow = TQTime::currentTime();
+    TQTimeEdit *timeEdit = new TQTimeEdit( timeNow, this );
+    timeEdit->setRange( timeNow, timeNow.addSecs( 60 * 60 ) );
+    \endcode
+    Here we've created a TQTimeEdit widget set to the current time.
+    We've also set the minimum value to the current time and the
+    maximum time to one hour from now.
+
+    The maximum and minimum values for a time value in the time editor
+    default to the maximum and minimum values for a TQTime. You can
+    change this by calling setMinValue(), setMaxValue() or setRange().
+
+    Terminology: A TQTimeWidget consists of three sections, one each
+    for the hour, minute and second. You can change the separator
+    character using setSeparator(), by default the separator is read
+    from the system's settings.

+    \class TQDateTimeEdit tqdatetimeedit.h
+    \brief The TQDateTimeEdit class combines a TQDateEdit and TQTimeEdit
+    widget into a single widget for editing datetimes.
+
+    \ingroup advanced
+    \ingroup time
+    \mainclass
+
+    TQDateTimeEdit consists of a TQDateEdit and TQTimeEdit 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 TQDateTimeEdit 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
+    TQDateEdit::setOrder() to change this. Times appear in the order
+    hours, minutes, seconds using the 24 hour clock.
+
+    It is recommended that the TQDateTimeEdit is initialised with a
+    datetime, e.g.
+    \code
+    TQDateTimeEdit *dateTimeEdit = new TQDateTimeEdit( TQDateTime::tqcurrentDateTime(), this );
+    dateTimeEdit->dateEdit()->setRange( TQDateTime::tqcurrentDate(),
+					TQDateTime::tqcurrentDate().addDays( 7 ) );
+    \endcode
+    Here we've created a new TQDateTimeEdit set to the current date and
+    time, and set the date to have a minimum date of now and a maximum
+    date of a week from now.
+
+    Terminology: A TQDateEdit widget consists of three 'sections', one
+    each for the year, month and day. Similarly a TQTimeEdit consists
+    of three sections, one each for the hour, minute and second. The
+    character that separates each date section is specified with
+    setDateSeparator(); similarly setTimeSeparator() is used for the
+    time sections.
