QDateTimeEdit Class Reference

Detailed Description

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 setAutoAdvance(). The datetime can be set with setDateTime().

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 QDateEdit::setOrder() to change this. Times appear in the order hours, minutes, seconds using the 24 hour clock.

It is recommended that the QDateTimeEdit is initialised with a datetime, e.g.

    QDateTimeEdit *dateTimeEdit = new QDateTimeEdit( QDateTime::currentDateTime(), this );
    dateTimeEdit->dateEdit()->setRange( QDateTime::currentDate(),
                                        QDateTime::currentDate().addDays( 7 ) );
    

Terminology: A QDateEdit widget consists of three 'sections', one each for the year, month and day. Similarly a QTimeEdit 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.
