## Detailed Description

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 range of valid values for a QDateTimeEdit is controlled by the properties minimumDateTime, maximumDateTime, and their respective date and time components. By default, any date-time from the start of 100 CE to the end of 9999 CE is valid.

### 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().

### Keyboard Tracking

When keyboard tracking is enabled (the default), every keystroke of editing a field triggers signals for value changes.

When the allowed range is narrower than some time interval whose end it straddles, keyboard tracking prevents the user editing the date or time to access the later part of the interval. For example, for a range from 29.04.2020 to 02.05.2020 and an initial date of 30.04.2020, the user can change neither the month (May 30th is outside the range) nor the day (April 2nd is outside the range).

When keyboard tracking is disabled, changes are only signalled when focus leaves the text field after edits have modified the content. This allows the user to edit via an invalid date-time to reach a valid one.

See also QDateEdit, QTimeEdit, QDate, and QTime.

## Property Documentation

### calendarPopup : bool

This property holds the current calendar pop-up show mode.

The calendar pop-up will be shown upon clicking the arrow button. This property is valid only if there is a valid date display format.

Access functions:

bool | calendarPopup() const
void | setCalendarPopup(bool enable)

See also setDisplayFormat().

### currentSection : Section

This property holds the current section of the spinbox.

Access functions:

QDateTimeEdit::Section | currentSection() const
void | setCurrentSection(QDateTimeEdit::Section section)

### currentSectionIndex : int

This property holds the current section index of the spinbox.

If the format is 'yyyy/MM/dd', the displayText is '2001/05/21', and the cursorPosition is 5, currentSectionIndex returns 1. If the cursorPosition is 3, currentSectionIndex is 0, and so on.

Access functions:

int | currentSectionIndex() const
void | setCurrentSectionIndex(int index)

See also setCurrentSection() and currentSection().

### date : QDate

This property holds the QDate that is set in the widget.

By default, this property contains a date that refers to January 1, 2000.

Access functions:

QDate | date() const
void | setDate(QDate date)

Notifier signal:

void | dateChanged(QDate date)

See also time and dateTime.

### dateTime : QDateTime

This property holds the QDateTime that is set in the QDateTimeEdit.

When setting this property, the new QDateTime is converted to the time system of the QDateTimeEdit, which thus remains unchanged.

By default, this property is set to the start of 2000 CE. It can only be set to a valid QDateTime value. If any operation causes this property to have an invalid date-time as value, it is reset to the value of the minimumDateTime property.

If the QDateTimeEdit has no date fields, setting this property sets the widget's date-range to start and end on the date of the new value of this property.

Access functions:

QDateTime | dateTime() const
void | setDateTime(const QDateTime &dateTime)

Notifier signal:

void | dateTimeChanged(const QDateTime &datetime)

See also date, time, minimumDateTime, maximumDateTime, and timeZone.

### displayFormat : QString

This property holds the format used to display the time/date of the date time edit.

This format is 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

Note that if you specify a two digit year, it will be interpreted to be in the century in which the date time edit was initialized. The default century is the 21st (2000-2099).

If you specify an invalid format the format will not be set.

Access functions:

QString | displayFormat() const
void | setDisplayFormat(const QString &format)

See also QDateTime::toString() and displayedSections().

### `[read-only]` displayedSections : const Sections

This property holds the currently displayed fields of the date time edit.

Returns a bit set of the displayed sections for this format.

Access functions:

QDateTimeEdit::Sections | displayedSections() const

See also setDisplayFormat() and displayFormat().

### maximumDate : QDate

This property holds the maximum date of the date time edit.

Changing this property updates the date of the maximumDateTime property while preserving the maximumTime property. When setting this property, the minimumDate is adjusted, if necessary, to ensure that the range remains valid. When this happens, the minimumTime property is also adjusted if it is greater than the maximumTime property. Otherwise, changes to this property preserve the minimumDateTime property.

This property can only be set to a valid QDate object describing a date on which the current maximumTime property makes a valid QDateTime object. The latest date that setMaximumDate() accepts is the end of 9999 CE. This is the default for this property. This default can be restored with clearMaximumDateTime().

Access functions:

QDate | maximumDate() const
void | setMaximumDate(QDate max)
void | clearMaximumDate()

See also minimumDate, maximumTime, maximumDateTime, setDateRange(), QDate::isValid(), and Keyboard Tracking.

### maximumDateTime : QDateTime

This property holds the maximum datetime of the date time edit.

Changing this property implicitly updates the maximumDate and maximumTime properties to the date and time parts of this property, respectively. When setting this property, the minimumDateTime is adjusted, if necessary, to ensure that the range remains valid. Otherwise, changing this property preserves the minimumDateTime property.

This property can only be set to a valid QDateTime value. The latest date-time that setMaximumDateTime() accepts is the end of 9999 CE. This is the default for this property. This default can be restored with clearMaximumDateTime().

Access functions:

QDateTime | maximumDateTime() const
void | setMaximumDateTime(const QDateTime &dt)
void | clearMaximumDateTime()

See also minimumDateTime, maximumTime, maximumDate(), setDateTimeRange(), QDateTime::isValid(), and Keyboard Tracking.

### maximumTime : QTime

This property holds the maximum time of the date time edit.

Changing this property updates the time of the maximumDateTime property while preserving the minimumDate and maximumDate properties. If those date properties coincide, when setting this property, the minimumTime property is adjusted, if necessary, to ensure that the range remains valid. Otherwise, changing this property preserves the minimumDateTime property.

This property can be set to any valid QTime value. By default, this property contains a time of 23:59:59 and 999 milliseconds. This default can be restored with clearMaximumTime().

Access functions:

QTime | maximumTime() const
void | setMaximumTime(QTime max)
void | clearMaximumTime()

See also minimumTime, maximumDate, maximumDateTime, setTimeRange(), QTime::isValid(), and Keyboard Tracking.

### minimumDate : QDate

This property holds the minimum date of the date time edit.

Changing this property updates the date of the minimumDateTime property while preserving the minimumTime property. When setting this property, the maximumDate is adjusted, if necessary, to ensure that the range remains valid. When this happens, the maximumTime property is also adjusted if it is less than the minimumTime property. Otherwise, changes to this property preserve the maximumDateTime property.

This property can only be set to a valid QDate object describing a date on which the current minimumTime property makes a valid QDateTime object. The earliest date that setMinimumDate() accepts is the start of 100 CE. The default for this property is September 14, 1752 CE. This default can be restored with clearMinimumDateTime().

Access functions:

QDate | minimumDate() const
void | setMinimumDate(QDate min)
void | clearMinimumDate()

See also maximumDate, minimumTime, minimumDateTime, setDateRange(), QDate::isValid(), and Keyboard Tracking.

### minimumDateTime : QDateTime

This property holds the minimum datetime of the date time edit.

Changing this property implicitly updates the minimumDate and minimumTime properties to the date and time parts of this property, respectively. When setting this property, the maximumDateTime is adjusted, if necessary, to ensure that the range remains valid. Otherwise, changing this property preserves the maximumDateTime property.

This property can only be set to a valid QDateTime value. The earliest date-time that setMinimumDateTime() accepts is the start of 100 CE. The property's default is the start of September 14, 1752 CE. This default can be restored with clearMinimumDateTime().

Access functions:

QDateTime | minimumDateTime() const
void | setMinimumDateTime(const QDateTime &dt)
void | clearMinimumDateTime()

See also maximumDateTime, minimumTime, minimumDate, setDateTimeRange(), QDateTime::isValid(), and Keyboard Tracking.

### minimumTime : QTime

This property holds the minimum time of the date time edit.

Changing this property updates the time of the minimumDateTime property while preserving the minimumDate and maximumDate properties. If those date properties coincide, when setting this property, the maximumTime property is adjusted, if necessary, to ensure that the range remains valid. Otherwise, changing this property preserves the maximumDateTime property.

This property can be set to any valid QTime value. By default, this property contains a time of 00:00:00 and 0 milliseconds. This default can be restored with clearMinimumTime().

Access functions:

QTime | minimumTime() const
void | setMinimumTime(QTime min)
void | clearMinimumTime()

See also maximumTime, minimumDate, minimumDateTime, setTimeRange(), QTime::isValid(), and Keyboard Tracking.

### `[until 6.10]` timeSpec : Qt::TimeSpec

This property is scheduled for deprecation in version 6.10.

Use QDateTimeEdit::timeZone instead.

This property holds the current timespec used by the date time edit.

Since Qt 6.7 this is an indirect accessor for the timeZone property.

Access functions:

Qt::TimeSpec | timeSpec() const
void | setTimeSpec(Qt::TimeSpec spec)

See also QDateTimeEdit::timeZone.

### `[since 6.7]` timeZone : QTimeZone

This property holds the current timezone used by the datetime editing widget

If the datetime format in use includes a timezone indicator - that is, a `t`, `tt`, `ttt` or `tttt` format specifier - the user's input is re-expressed in this timezone whenever it is parsed, overriding any timezone the user may have specified.

This property was introduced in Qt 6.7.

Access functions:

QTimeZone | timeZone() const
void | setTimeZone(const QTimeZone &zone)

See also calendar().

### void QDateTimeEdit::setCalendarWidget(QCalendarWidget *calendarWidget)

Sets the given calendarWidget as the widget to be used for the calendar pop-up. The editor does not automatically take ownership of the calendar widget.

Note: calendarPopup must be set to true before setting the calendar widget.

See also calendarWidget() and calendarPopup.

### void QDateTimeEdit::setDateRange(QDate min, QDate max)

Set the range of allowed dates for the date time edit.

This convenience function sets the minimumDate and maximumDate properties.

     setDateRange(min, max);

is analogous to:

     setMinimumDate(min);
     setMaximumDate(max);

If either min or max is invalid, this function does nothing. This function preserves the minimumTime property. If max is less than min, the new maximumDateTime property shall be the new minimumDateTime property. If max is equal to min and the maximumTime property was less then the minimumTime property, the maximumTime property is set to the minimumTime property. Otherwise, this preserves the maximumTime property.

If the range is narrower then a time interval whose end it spans, for example a week that spans the end of a month, users can only edit the date to one in the later part of the range if keyboard-tracking is disabled.

See also minimumDate, maximumDate, setDateTimeRange(), QDate::isValid(), and Keyboard Tracking.

### void QDateTimeEdit::setDateTimeRange(const QDateTime &min, const QDateTime &max)

Set the range of allowed date-times for the date time edit.

This convenience function sets the minimumDateTime and maximumDateTime properties.

     setDateTimeRange(min, max);

is analogous to:

     setMinimumDateTime(min);
     setMaximumDateTime(max);

If either min or max is invalid, this function does nothing. If max is less than min, min is used also as max.

If the range is narrower then a time interval whose end it spans, for example a week that spans the end of a month, users can only edit the date-time to one in the later part of the range if keyboard-tracking is disabled.

See also minimumDateTime, maximumDateTime, setDateRange(), setTimeRange(), QDateTime::isValid(), and Keyboard Tracking.

### void QDateTimeEdit::setSelectedSection(QDateTimeEdit::Section section)

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.

See also currentSection().

### void QDateTimeEdit::setTimeRange(QTime min, QTime max)

Set the range of allowed times for the date time edit.

This convenience function sets the minimumTime and maximumTime properties.

Note that these only constrain the date time edit's value on, respectively, the minimumDate and maximumDate. When these date properties do not coincide, times after max are allowed on dates before maximumDate and times before min are allowed on dates after minimumDate.

     setTimeRange(min, max);

is analogous to:

     setMinimumTime(min);
     setMaximumTime(max);

If either min or max is invalid, this function does nothing. This function preserves the minimumDate and maximumDate properties. If those properties coincide and max is less than min, min is used as max.

If the range is narrower then a time interval whose end it spans, for example the interval from ten to an hour to ten past the same hour, users can only edit the time to one in the later part of the range if keyboard-tracking is disabled.

See also minimumTime, maximumTime, setDateTimeRange(), QTime::isValid(), and Keyboard Tracking.

### `[override virtual]` QSize QDateTimeEdit::sizeHint() const

Reimplements: QAbstractSpinBox::sizeHint() const.

### `[override virtual]` void QDateTimeEdit::stepBy(int steps)

Reimplements: QAbstractSpinBox::stepEnabled() const.

### `[virtual protected]` QString QDateTimeEdit::textFromDateTime(const QDateTime &dateTime) const

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 validate().

See also dateTimeFromText() and validate().

### QTime QDateTimeEdit::time() const

Returns the time of the date time edit.

Note: Getter function for property time.

See also setTime().

### `[signal]` void QDateTimeEdit::timeChanged(QTime time)

This signal is emitted whenever the time is changed. The new time is passed in time.

Note: Notifier signal for property time.

See also Keyboard Tracking.

### `[override virtual protected]` QValidator::State QDateTimeEdit::validate(QString &text, int &pos) const

Reimplements: QAbstractSpinBox::validate(QString &input, int &pos) const.
