The QDateTimeEdit class provides a widget for editing dates and times.
QDateTimeEdit allows the user to edit dates by using the keyboard or the arrow keys to increase and decrease date and time values. The arrow keys can be used to move from section to section within the QDateTimeEdit box. Dates and times appear in accordance with the format set; see setDisplayFormat().
QDateTimeEdit *dateEdit = new QDateTimeEdit(QDate::currentDate());
dateEdit->setMinimumDate(QDate::currentDate().addDays(-365));
dateEdit->setMaximumDate(QDate::currentDate().addDays(365));
dateEdit->setDisplayFormat("yyyy.MM.dd");
Here we've created a new QDateTimeEdit object initialized 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.
The maximum and minimum values for a date value in the date editor default to the maximum and minimum values for a QDate. You can change this by calling setMinimumDate(), setMaximumDate(), setMinimumTime(), and setMaximumTime().

The Sections type is a typedef for QFlags<Section>. It stores an OR combination of Section values.
This property holds the current calender popup showing mode.
The calendar popup will be shown upon clicking the arrow button. This property is valid only if there is a valid date display format.
This property was introduced in Qt 4.2.
Access functions:
See also setDisplayFormat().
This property holds the current section of the spinbox setCurrentSection().
Access functions:
This property holds the QDate that is set in the QDateTimeEdit.
Access functions:
See also time.
This property holds the QDateTime that is set in the QDateTimeEdit.
Access functions:
See also minimumDate, minimumTime, maximumDate, and maximumTime.
This property holds the format used to display the time/date of the date time edit.
This format is the same as the one used described in QDateTime::toString() and QDateTime::fromString()
Example format strings(assuming that the date is 2nd of July 1969):
| Format | Result |
|---|---|
| dd.MM.yyyy | 02.07.1969 |
| MMM d yy | Jul 2 69 |
| MMMM d yy | July 2 69 |
If you specify an invalid format the format will not be set.
Access functions:
See also QDateTime::toString() and displayedSections().
This property holds the currently displayed fields of the date time edit.
Returns a bit set of the displayed sections for this format. setDisplayFormat(), displayFormat()
Access functions:
This property holds the maximum date of the date time edit.
When setting this property the minimumDate is adjusted if necessary to ensure that the range remains valid. If the date is not a valid QDate object, this function does nothing.
Access functions:
See also minimumDate, minimumTime, maximumTime, and setDateRange().
This property holds the maximum time of the date time edit.
When setting this property, the minimumTime is adjusted if necessary to ensure that the range remains valid. If the time is not a valid QTime object, this function does nothing.
Access functions:
See also minimumTime, minimumDate, maximumDate, and setTimeRange().
This property holds the minimum date of the date time edit.
When setting this property the maximumDate is adjusted if necessary, to ensure that the range remains valid. If the date is not a valid QDate object, this function does nothing.
Access functions:
See also minimumTime, maximumTime, and setDateRange().
This property holds the minimum time of the date time edit.
When setting this property the maximumTime is adjusted if necessary, to ensure that the range remains valid. If the time is not a valid QTime object, this function does nothing.
Access functions:
See also maximumTime, minimumDate, maximumDate, and setTimeRange().
This property holds the QTime that is set in the QDateTimeEdit.
Access functions:
See also date.
Constructs an empty date time editor with a parent.
Constructs an empty date time editor with a parent. The value is set to datetime.
Constructs an empty date time editor with a parent. The value is set to date.
Constructs an empty date time editor with a parent. The value is set to time.
This signal is emitted whenever the date is changed. The new date is passed in date.
This signal is emitted whenever the date or time is changed. The new date and time is passed in datetime.
Returns an appropriate datetime for the given text.
This virtual function is used by the datetime edit whenever it needs to interpret text entered by the user as a value.
See also textFromDateTime() and validate().
Returns the text from the given section.
### note about not working when not Acceptable
See also currentSection().
Convenience function to set minimum and maximum date with one function call.
setDateRange(min, max);
is analogous to:
setMinimumDate(min); setMaximumDate(max);
If either min or max are not valid, this function does nothing.
See also setMinimumDate(), maximumDate(), setMaximumDate(), clearMinimumDate(), setMinimumTime(), maximumTime(), setMaximumTime(), clearMinimumTime(), and QDate::isValid().
Selects section. If section doesn't exist in the currently displayed sections this function does nothing. If section is NoSection this function will unselect all text in the editor. Otherwise this function will move the cursor and the current section to the selected section.
This function was introduced in Qt 4.2.
See also currentSection().
Convenience function to set minimum and maximum time with one function call.
setTimeRange(min, max);
is analogous to:
setMinimumTime(min); setMaximumTime(max);
If either min or max are not valid, this function does nothing.
See also setMinimumDate(), maximumDate(), setMaximumDate(), clearMinimumDate(), setMinimumTime(), maximumTime(), setMaximumTime(), clearMinimumTime(), and QTime::isValid().
This virtual function is used by the date time edit whenever it needs to display dateTime.
If you reimplement this, you may also need to reimplement valueFromText() and validate().
See also dateTimeFromText() and validate().
This signal is emitted whenever the time is changed. The new time is passed in time.
