|

|

|

|
|
The QDateTimeEdit class combines a <a href="qdateedit.html">QDateEdit</a> and <a href="qtimeedit.html">QTimeEdit</a>
|
||
|
|
widget into a single widget for editing datetimes.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
|
||
|
|
<p> QDateTimeEdit consists of a QDateEdit and QTimeEdit 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 QDateTimeEdit widget, and
|
||
|
|
the user 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 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="qdateedit.html#setOrder">QDateEdit::setOrder</a>() to change this. Times appear in the order
|
||
|
|
hours, minutes, seconds using the 24 hour clock.
|
||
|
|
<p> It is recommended that the QDateTimeEdit is initialised with a
|
||
|
|
datetime, 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 and
|
||
|
|
time, and set the date to have a minimum date of now and a maximum
|
||
|
|
date of a week from now.
|
||
|
|
<p> Terminology: A <a href="qdateedit.html">QDateEdit</a> widget consists of three 'sections', one
|
||
|
|
each for the year, month and day. Similarly a <a href="qtimeedit.html">QTimeEdit</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.
