Detailed Description

The QDateTimeEdit class provides a widget for editing dates and times.

\inmodule QtWidgets

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 \l minimumDateTime, \l 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.

Otherwise, this preserves the \l 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.

◆ calendarPopup

QDateTimeEdit::calendarPopup

Since: 4.2

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.

See also: setDisplayFormat()

◆ currentSectionIndex

QDateTimeEdit::currentSectionIndex

readwrite

The current section index of the spinbox.

Since: 4.3

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.

See also: setCurrentSection(), currentSection()

Definition at line 200 of file qdatetimeedit.h.

◆ date

QDateTimeEdit::date

readwrite

The QDate that is set in the widget.

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

See also: time, dateTime

Definition at line 200 of file qdatetimeedit.h.

Referenced by QDateTimeEdit(), setDate(), and setDateTime().

◆ dateTime

QDateTimeEdit::dateTime

readwrite

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 \l 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.

The currently displayed fields of the date time edit.

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

See also: setDisplayFormat(), displayFormat()

Definition at line 200 of file qdatetimeedit.h.

Referenced by stepBy().

◆ displayFormat

QDateTimeEdit::displayFormat

readwrite

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):

\table \header

Format
Result \row
dd.MM.yyyy
02.07.1969 \row
MMM d yy
Jul 2 69 \row
MMMM d yy
July 2 69 \endtable

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.

See also: QDateTime::toString(), displayedSections()

Definition at line 200 of file qdatetimeedit.h.

◆ maximumDate

QDateTimeEdit::maximumDate

readwrite

The maximum date of the date time edit.

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

This property can only be set to a valid QDate object describing a date on which the current \l 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().

See also: minimumDate, maximumTime, maximumDateTime, setDateRange(), QDate::isValid(), {Keyboard Tracking}

Definition at line 200 of file qdatetimeedit.h.

◆ maximumDateTime

QDateTimeEdit::maximumDateTime

readwrite

The maximum datetime of the date time edit.

Since: 4.4

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

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