The user can editthe date and time by using the keyboard or the arrow keys toincrease/decrease date or time values. The Tab key can be used tomove from section to section within the QDateTimeEdit widget, and theuser can be moved automatically when they complete a section using<a href="#setAutoAdvance">setAutoAdvance</a>(). The datetime can be set with <a href="#setDateTime">setDateTime</a>().<p> The dateformat is read from the system's locale settings. It is set toyear, month, day order if that is not possible. see <a href="qdateedit.html#setOrder">QDateEdit::setOrder</a>()to change this. Times appear in the order hours, minutes, secondsusing the 24 hour clock.<p> It is recommended that the QDateTimeEdit is initialised with adatetime, e.g.<pre> QDateTimeEdit *dateTimeEdit = new QDateTimeEdit( QDateTime::<a href="qdatetime.html#currentDateTime">currentDateTime</a>(), this ); dateTimeEdit-><a href="#dateEdit">dateEdit</a>()->setRange( QDateTime::currentDate(), QDateTime::currentDate().addDays( 7 ) ); </pre> Here we've created a new QDateTimeEdit set to the current date andtime, and set the date to have a minimum date of now and a maximumdate of a week from now.<p> Terminology: A <a href="qdateedit.html">QDateEdit</a> widget consists of three 'sections', one eachfor the year, month and day. Similarly a <a href="qtimeedit.html">QTimeEdit</a> consists of threesections, one each for the hour, minute and second. The character thatseparates each date section is specified with setDateSeparator();similarly setTimeSeparator() is used for the time sections.<p> <center><img src="datetimewidgets.png" alt="Date Time Widgets"></center> <p> <p>See also <a href="qdateedit.html">QDateEdit</a>, <a href="qtimeedit.html">QTimeEdit</a>, <a href="advanced.html">Advanced Widgets</a> and <a href="time.html">Time and Date</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn><a name="QDateTimeEdit"></a>QDateTimeEdit::QDateTimeEdit ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )</h3> Constructs an empty datetime edit with parent <em>parent</em> and name<em>name</em>.<p> <h3 class=fn><a name="QDateTimeEdit-2"></a>QDateTimeEdit::QDateTimeEdit ( const <a href="qdatetime.html">QDateTime</a> & datetime, <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )</h3>This is an overloaded member function, provided for convenience.
