The arrow keys can be used to move from section to section within the TQDateEdit box. Dates appear in accordance with the local date/time settings or in year, month, day order if the system doesn't provide this information. It is recommended that the TQDateEdit be initialised with a date, e.g. \code TQDateEdit *dateEdit = new TQDateEdit( TQDate::currentDate(), this ); dateEdit->setRange( TQDate::currentDate().addDays( -365 ), TQDate::currentDate().addDays( 365 ) ); dateEdit->setOrder( TQDateEdit::MDY ); dateEdit->setAutoAdvance( TRUE ); \endcode Here we've created a new TQDateEdit object initialised 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. If the auto advance property is TRUE (as we've set it here) when the user completes a section of the date, e.g. enters two digits for the month, they are automatically taken to the next section. The maximum and minimum values for a date value in the date editor default to the maximum and minimum values for a TQDate. You can change this by calling setMinValue(), setMaxValue() or setRange(). Terminology: A TQDateEdit widget comprises three 'sections', one each for the year, month and day. You can change the separator character using TQDateTimeEditor::setSeparator(), by default the separator will be taken from the systems settings. If that is not possible, it defaults to "-". \img datetimewidgets.png Date Time Widgets \sa TQDate TQTimeEdit TQDateTimeEdit */ /*! \enum TQDateEdit::Order This enum defines the order in which the sections that comprise a date appear. \value MDY month-day-year \value DMY day-month-year \value YMD year-month-day (the default) \value YDM year-day-month (included for completeness; but should not be used) */ /*! \enum TQTimeEdit::Display This enum defines the sections that comprise a time \value Hours The hours section \value Minutes The minutes section \value Seconds The seconds section \value AMPM The AM/PM section The values can be or'ed together to show any combination. */ /*!

The arrow keys can be used to move from section to section within the TQTimeEdit box. The user can automatically be moved to the next section once they complete a section using setAutoAdvance(). Times appear in hour, minute, second order. It is recommended that the TQTimeEdit is initialised with a time, e.g. \code TQTime timeNow = TQTime::currentTime(); TQTimeEdit *timeEdit = new TQTimeEdit( timeNow, this ); timeEdit->setRange( timeNow, timeNow.addSecs( 60 * 60 ) ); \endcode Here we've created a TQTimeEdit widget set to the current time.

The maximum and minimum values for a time value in the time editor default to the maximum and minimum values for a TQTime. You can change this by calling setMinValue(), setMaxValue() or setRange(). Terminology: A TQTimeWidget consists of three sections, one each for the hour, minute and second.

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 TQDateTimeEdit 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 TQDateEdit::setOrder() to change this. Times appear in the order hours, minutes, seconds using the 24 hour clock. It is recommended that the TQDateTimeEdit is initialised with a datetime, e.g. \code TQDateTimeEdit *dateTimeEdit = new TQDateTimeEdit( TQDateTime::currentDateTime(), this ); dateTimeEdit->dateEdit()->setRange( TQDateTime::currentDate(), TQDateTime::currentDate().addDays( 7 ) ); \endcode Here we've created a new TQDateTimeEdit 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. Terminology: A TQDateEdit widget consists of three 'sections', one each for the year, month and day. Similarly a TQTimeEdit 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. \img datetimewidgets.png Date Time Widgets \sa TQDateEdit TQTimeEdit */ /*!
