\class QDateTimeEdit qdatetimeedit.h
\brief The QDateTimeEdit class provides a widget for editing dates and times.
\ingroup basic
\mainclass
QDateTimeEdit allows the user to edit dates by using the keyboard or
the arrow keys to increase and decrease date and time values. The
arrow keys can be used to move from section to section within the
QDateTimeEdit box. Dates and times appear in accordance with the
format set; see setDisplayFormat().
\code
QDateTimeEdit *dateEdit = new QDateTimeEdit(QDate::currentDate());
dateEdit->setMinimumDate(QDate::currentDate().addDays(-365));
dateEdit->setMaximumDate(QDate::currentDate().addDays(365));
dateEdit->setDisplayFormat("yyyy.MM.dd");
\endcode
Here we've created a new QDateTimeEdit object initialized 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.
The maximum and minimum values for a date value in the date editor
default to the maximum and minimum values for a QDate. You can
change this by calling setMinimumDate(), setMaximumDate(),
setMinimumTime(), and setMaximumTime().
