You can change this by calling - setMinimumDate(), setMaximumDate(), setMinimumTime(), - and setMaximumTime(). - - \section1 Using a Pop-up Calendar Widget - - QDateTimeEdit can be configured to allow a QCalendarWidget to be used - to select dates. This is enabled by setting the calendarPopup property. - Additionally, you can supply a custom calendar widget for use as the - calendar pop-up by calling the setCalendarWidget() function.
