    \class HbDateTimePicker
    \brief The HbDateTimePicker class provides a widget that has multiple vertical tumblers 
    for selecting a date, time, or date and time by flick, drag and tap gestures.
    
    The number of tumblers depends on the display format. The default constructor creates
    a widget for selecting a date by internally setting the display format to the default 
    locale's short date format. Other constructors enable you to create a widget
    for selecting a time or date and time by passing a QTime or QDateTime variable as an 
    argument. Internally these constructors set the display format to the default locale's
    short time or date and time format, respectively.
    
    Use setDisplayFormat() to set the display format. Be aware that changing the display format 
    can change the widget from one for selecting the date to one for selecting the time, for 
    example.
    
    Looping is enabled in the tumblers. The general appearance of the widget depends on the 
    theme that is in use.
    
    <TABLE border="0">
    <TR><TD>\image html hbdatetimepicker_date.png "Display format: d.MMMM"</TD>
    <TD></TD>
    <TD>\image html hbdatetimepicker_time.png "Display format: h.m.AP"</TD></TR>
    </TABLE>
    
    You can set the range of values available in the tumblers by defining minimum and maximum 
    values or using convenience range functions. If you change the range, if necessary 
    the widget changes the displayed values so that they are within the new range. Users 
    cannot select a value outside the range. One effect of this is that if you set, 
    for example, an afternoon time range, users cannot scroll to the AM value when the 
    display format includes an AM/PM tumbler. The date range is currently independent of the 
    time range.
    
    You can use setInterval() to define the increments for the minute tumbler. This is 
    useful when you want users to be able to set the time in 15 minute increments, for example.
    
    The number of rows displayed depends on how much space is available. To change the number 
    of rows shown when the widget is is in a layout, for example, use 
    QGraphicsLayoutItem::setPreferredHeight() to increase the space available. The widget then
    increases the number of rows to occupy the available space. 
    
    %HbDateTimePicker emits a dateChanged(), timeChanged() or dateTimeChanged() signal when 
    the user selects a new value. The selected date, time, or date and time value is passed
    in a QDate, QTime, or QDateTime argument. 
    
    \section _usecases_hbdatetimepicker Using HbDateTimePicker
    
    The following example demonstrates creating a widget for selecting a date:
    
    \code
    // Use the default constructor to create a widget for selecting a date.
    HbDateTimePicker *datePicker = new HbDateTimePicker();

    // Set the minumum and maximum dates to display.
    datePicker->setMinimumDate(QDate::currentDate());
    datePicker->setMaximumDate(QDate::currentDate().addDays(365));

    // Specify the display format.
    datePicker->setDisplayFormat("dd.MMMM.yyyy");
    \endcode
    
    The following example demonstrates connecting the dateChanged() signal to a slot
    on an object, \a d, of a class (not shown). This has a \c setMeetingDate() function 
    that takes a QDate argument.
    
    \code
    QObject::connect(datePicker, SIGNAL(dateChanged(const QDate&)),
                     d, SLOT(setMeetingDate(const QDate&)));
    \endcode

    The following example demonstrates creating a widget for selecting a time:
    
    \code
    // Create a widget for selecting a time.
    HbDateTimePicker *timePicker = new HbDateTimePicker(QTime());

    // Set the minimum and maximum times using the convenience range method.
    timePicker->setTimeRange(QTime::currentTime(),
                             QTime::currentTime().addSecs(10*60*60));
    
    // Set the time interval to be 15 minutes.
    timePicker->setInterval(QDateTimeEdit::MinuteSection, 15);
    
    // Specify the display format.
    timePicker->setDisplayFormat("hh:mm.ap");
    \endcode
    
    The following example demonstrates creating a widget for selecting a date and time:
    
    \code
    // Create a widget for selecting a date and time.
    HbDateTimePicker *dateTimePicker =
            new HbDateTimePicker(QDateTime::currentDateTime());

    // Specify the display format.
    dateTimePicker->setDisplayFormat("dd.MM.yyyy.hh.mm.ap");
    \endcode
    
    The properties that hold the minimum and maximum values take a QDate, QTime 
    or QDateTime object as an argument. DocML does not directly support properties that
    use QDate, QTime or QDateTime as a parameter. This means that when you add an \b %HbDateTimePicker 
    widget in Application Designer, you must pass the date, time and date and time to these
    properties as a string in a valid ISO 8601 extended format. For example, YYYY-MM-DD for dates, 
    hh:mm:ss for times, and YYYY-MM-DDTHH:MM:SS for combined dates and times. 
    
    Here is an example of the \c maximumTime property defined in DocML:
    
    \code
    <widget name="t:dtp" type="HbDateTimePicker">
        <!-- 'maximumTime' is a QTime property of HbDateTimePicker. -->
        <string name ="displayFormat" value="hh:mm:ss" />
        <string name="maximumTime" value="08:30:00" />
    </widget>
    \endcode
    
    \section _methodgroups_HbDateTimePicker Function groups
    
    \li \b Range: setDateRange(), setTimeRange(), setDateTimeRange()
    \li \b Minimum \b value: setMinimumDate(), setMinimumTime(), setMinimumDateTime()
    \li \b Maximum \b value: setMaximumDate(), setMaximumTime(), setMaximumDateTime()
    \li \b Time \b interval: setInterval()
