Detailed Description

The QDateTimeEdit class provides a widget for editing dates and times. The user can edit dates by using the keyboard or the arrow keys to increase and decrease date and time values. The arrow keys also be can be used to move from section to section within the QDateTimeEdit box. Dates and times appear in accordance with the format set.

In the following example we are creating a new QDateTimeEdit object initialized with today's date. Then the maximum and minimum valid date range is set to plus or minus 365 days. Calling setDisplayFormat() allows changing the date display format.

QDateTimeEdit *dateEdit = new QDateTimeEdit(QDate::currentDate());
 
dateEdit->setMinimumDate(QDate::currentDate().addDays(-365));
dateEdit->setMaximumDate(QDate::currentDate().addDays(365));
dateEdit->setDisplayFormat("yyyy.MM.dd");

Using a Pop-up Calendar Widget

QDateTimeEdit can be configured to allow a QCalendarWidget to be used to select dates. This is enabled by setting the calendarPopup property. Additionally, you can supply a custom calendar widget for use as the calendar pop-up by calling the setCalendarWidget() function. The existing calendar widget can be retrieved with calendarWidget().

	A date time editing widget shown in the Windows XP widget style.
	A date time editing widget shown in the Mac OS X widget style.
	A date time editing widget shown in the Fusion widget style.

Method Documentation

bool QDateTimeEdit::calendarPopup ( ) const

Returns the value of the property.

QCalendarWidget * QDateTimeEdit::calendarWidget ( ) const

Returns the calendar widget for the editor if calendarPopup is set to true and (sections() & DateSections_Mask) != 0. This method creates and returns a calendar widget if none has been set.
