Detailed Description#
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
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()
.
dateEdit = 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.

Note
Properties can be used directly when from __feature__ import true_property
is used or via accessor functions otherwise.
- property PᅟySide6.QtWidgets.QDateTimeEdit.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:
setCalendarPopup
(enable)
- property PᅟySide6.QtWidgets.QDateTimeEdit.currentSection: Section#
This property holds The current section of the spinbox..
- Access functions:
setCurrentSection
(section)
- property PᅟySide6.QtWidgets.QDateTimeEdit.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:
setCurrentSectionIndex
(index)
- property PᅟySide6.QtWidgets.QDateTimeEdit.date: PySide6.QtCore.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:
date
()setDate
(date)Signal
dateChanged
(date)
- property PᅟySide6.QtWidgets.QDateTimeEdit.dateTime: PySide6.QtCore.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:
dateTime
()setDateTime
(dateTime)Signal
dateTimeChanged
(dateTime)
- property PᅟySide6.QtWidgets.QDateTimeEdit.displayFormat: str#
This property holds The format used to display the time/date of the date time edit..
This format is described in toString()
and 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.

displayedSections()
- Access functions:
setDisplayFormat

- property PᅟySide6.QtWidgets.QDateTimeEdit.displayedSections: 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:
- property PᅟySide6.QtWidgets.QDateTimeEdit.maximumDate: PySide6.QtCore.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()
.

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.

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.

Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
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.
