<h2>Detailed Description</h2>

<p>The Q3DateTimeEdit class combines a <a href="q3dateedit.html">Q3DateEdit</a> and <a href="q3timeedit.html">Q3TimeEdit</a> widget into a single widget for editing datetimes.</p>

<p>Q3DateTimeEdit consists of a <a href="q3dateedit.html">Q3DateEdit</a> and <a href="q3timeedit.html">Q3TimeEdit</a> 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 Q3DateTimeEdit widget, and the user can be moved automatically when they complete a section using <a href="q3datetimeedit.html#setAutoAdvance">setAutoAdvance</a>(). The datetime can be set with <a href="q3datetimeedit.html#dateTime-prop">setDateTime</a>().</p>

<p>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 <a href="q3dateedit.html#order-prop">Q3DateEdit::setOrder</a>() to change this. Times appear in the order hours, minutes, seconds using the 24 hour clock.</p>

<p>It is recommended that the Q3DateTimeEdit is initialised with a datetime, e.g.</p>

<pre>  Q3DateTimeEdit *dateTimeEdit = new Q3DateTimeEdit(QDateTime::currentDateTime(), this);

dateTimeEdit->dateEdit()->setRange(QDateTime::currentDate(),

QDateTime::currentDate().addDays(7));</pre>

<p>Here we've created a new Q3DateTimeEdit 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.</p>

<p>Terminology: A <a href="q3dateedit.html">Q3DateEdit</a> widget consists of three 'sections', one each for the year, month and day. Similarly a <a href="q3timeedit.html">Q3TimeEdit</a> 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.</p>
