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.

This property was introduced in Qt 4.2.

Access functions:

See also setDisplayFormat().

currentSection : Section

This property holds the current section of the spinbox.

Access functions:

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.

This property was introduced in Qt 4.3.

Access functions:

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:

Notifier signal:

See also time and dateTime.

dateTime : QDateTime

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

When setting this property the timespec of the QDateTimeEdit remains the same and the timespec of the new QDateTime is ignored.

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:

Notifier signal:

See also date, time, minimumDateTime, and maximumDateTime.

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):

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:

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

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:

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:

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().

This property was introduced in Qt 4.4.

Access functions:

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:

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:

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 minimumDateTime 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().

This property was introduced in Qt 4.4.

Access functions:

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().
