Property Documentation

calendarPopup : bool

This property holds the current calendar pop-up showing 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:

bool	calendarPopup() const
void	setCalendarPopup(bool enable)

See also setDisplayFormat().

currentSection : Section

This property holds the current section of the spinbox setCurrentSection().

Access functions:

Section	currentSection() const
void	setCurrentSection(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 etc.

setCurrentSection()

This property was introduced in Qt 4.3.

Access functions:

int	currentSectionIndex() const
void	setCurrentSectionIndex(int index)

See also 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(const QDate & date)

Notifier signal:

void	dateChanged(const 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 timespec of the QDateTimeEdit remains the same and the timespec of the new QDateTime is ignored.

By default, this property contains a date that refers to January 1, 2000 and a time of 00:00:00 and 0 milliseconds.

Access functions:

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

Notifier signal:

void	dateTimeChanged(const QDateTime & datetime)

See also date and time.

displayFormat : QString

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

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 21 (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().

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. setDisplayFormat(), displayFormat()

Access functions:

Sections

displayedSections() const

maximumDate : QDate

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.

By default, this property contains a date that refers to December 31, 7999.

Access functions:

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

See also minimumDate, minimumTime, maximumTime, and setDateRange().

maximumDateTime : QDateTime

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

When setting this property the minimumDateTime() is adjusted if necessary to ensure that the range remains valid. If the datetime is not a valid QDateTime object, this function does nothing.

The default maximumDateTime can be restored with clearMaximumDateTime().

By default, this property contains a date that refers to 31 December, 7999 and a time of 23:59:59 and 999 milliseconds.

This property was introduced in Qt 4.4.

Access functions:

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

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.

By default, this property contains a time of 23:59:59 and 999 milliseconds.

Access functions:

QTime	maximumTime() const

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

See also minimumTime(), maximumTime(), and setDateRange().

minimumDateTime : QDateTime

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