💜 DESCRIPTION 💜

Okay so. The QDateEdit class provides a date editor. Periodt.

QDateEdit lets the user edit dates by typing on the keyboard, or by smashing the arrow keys to increase/decrease the date values. Those arrow keys also move you from section to section inside the QDateEdit box. Dates show up following the local date/time settings — or, if your system is being unhelpful and doesn't provide that info, in year, month, day order. And like, the docs are literally begging you: initialise your QDateEdit with a date, bestie. For example:

QDateEdit *dateEdit = new QDateEdit( QDate::currentDate(), this );
dateEdit->setRange( QDate::currentDate().addDays( -365 ),
                    QDate::currentDate().addDays(  365 ) );
dateEdit->setOrder( QDateEdit::MDY );
dateEdit->setAutoAdvance( TRUE );

So what did we just do? We made a brand-new QDateEdit object initialised with today's date, and we restricted the valid date range to today plus or minus 365 days. Then we set the order to month, day, year. And if the auto advance property is TRUE (which, yes, we set it right there), the moment the user finishes a section of the date — like entering two digits for the month — they get automatically whisked away to the next section. Iconic behaviour honestly ✨

The maximum and minimum values for a date value in the date editor default to the maximum and minimum values for a QDate. Wanna change that? Call setMinValue(), setMaxValue() or setRange(). Easy.

Terminology time, because we're being precise: a QDateEdit widget is made up of three 'sections' — one each for the year, month and day. You can change the separator character using QDateTimeEditor::setSeparator(). By default the separator gets taken from the system settings. And if that's just not possible? It defaults to "-". No drama.

📚 Member Type Documentation 📚

QDateEdit::Order

This enum defines the order in which the sections that comprise a date appear. Let's go:

QDateEdit::MDY — month-day-year
QDateEdit::DMY — day-month-year
QDateEdit::YMD — year-month-day (the default)
QDateEdit::YDM — year-day-month (included for completeness; but should not be used)

That last one? Included for completeness but like... should not be used. She said what she said 💀

🛠️ MEMBER FUNCTION DOCUMENTATION 🛠️

`QDateEdit::QDateEdit ( QWidget * parent = 0, const char * name = 0 )`

Constructs an empty date editor which is a child of parent and called name name.

`QDateEdit::QDateEdit ( const QDate & date, QWidget * parent = 0, const char * name = 0 )`

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Constructs a date editor with the initial value date, parent parent and called name.

The date editor is initialized with date.

`QDateEdit::~QDateEdit ()`

Destroys the object and frees any allocated resources. Cleanup queen 🧹✨

`bool QDateEdit::autoAdvance () const`

Returns TRUE if the editor automatically advances to the next section; otherwise returns FALSE. See the "autoAdvance" property for details.

`QDate QDateEdit::date () const`

Returns the editor's date value. See the "date" property for details.

`void QDateEdit::fix ()` [virtual protected]

Attempts to fix any invalid date entries. She's a fixer, it's giving damage control 💅

The rules applied are as follows:

If the year has four digits it is left unchanged.
If the year has two digits, the year will be changed to four digits in the range current year - 70 to current year + 29.
If the year has three digits in the range 100..999, the current millennium, i.e. 2000, will be added giving a year in the range 2100..2999.
If the day or month is 0 then it will be set to 1 or the minimum valid day\month in the range.

`QDate QDateEdit::maxValue () const`

Returns the editor's maximum value. See the "maxValue" property for details.

`QDate QDateEdit::minValue () const`

Returns the editor's minimum value. See the "minValue" property for details.

`Order QDateEdit::order () const`

Returns the order in which the year, month and day appear. See the "order" property for details.

`QString QDateEdit::sectionFormattedText ( int sec )` [virtual protected]

Returns the formatted number for section sec. This will correspond to either the year, month or day section, depending on the current display order.

`QString QDateEdit::separator () const`

Returns the editor's separator.

`void QDateEdit::setAutoAdvance ( bool advance )` [virtual]

Sets whether the editor automatically advances to the next section to advance. See the "autoAdvance" property for details.

`void QDateEdit::setDate ( const QDate & date )` [virtual slot]

Sets the editor's date value to date. See the "date" property for details.

`void QDateEdit::setDay ( int day )` [virtual protected]

Sets the day to day, which must be a valid day. The function will ensure that the day set is valid for the month and year. No invalid days on her watch 🫶

`void QDateEdit::setMaxValue ( const QDate & d )` [virtual]

Sets the editor's maximum value to d. See the "maxValue" property for details.

`void QDateEdit::setMinValue ( const QDate & d )` [virtual]

Sets the editor's minimum value to d. See the "minValue" property for details.

`void QDateEdit::setMonth ( int month )` [virtual protected]

Sets the month to month, which must be a valid month, i.e. between 1 and 12.

`void QDateEdit::setOrder ( Order order )` [virtual]

Sets the order in which the year, month and day appear to order. See the "order" property for details.

`void QDateEdit::setRange ( const QDate & min, const QDate & max )` [virtual]

Sets the valid input range for the editor to be from min to max inclusive. If min is invalid no minimum date will be set. Similarly, if max is invalid no maximum date will be set.

`void QDateEdit::setSeparator ( const QString & s )` [virtual]

Sets the separator to s. Note that currently only the first character of s is used. Yeah, just the one. Don't overthink it 🙈

`void QDateEdit::setYear ( int year )` [virtual protected]

Sets the year to year, which must be a valid year. The range currently supported is from 1752 to 8000.

`void QDateEdit::updateButtons ()` [protected slot]

Enables/disables the push buttons according to the min/max date for this widget.

`void QDateEdit::valueChanged ( const QDate & date )` [signal]

This signal is emitted whenever the editor's value changes. The date parameter is the new value. Bestie is changing and she wants you to know 💖

🏷️ Property Documentation 🏷️

`bool autoAdvance`

This property holds whether the editor automatically advances to the next section.

If autoAdvance is TRUE, the editor will automatically advance focus to the next date section if a user has completed a section. The default is FALSE.

Set this property's value with setAutoAdvance() and get this property's value with autoAdvance().

`QDate date`

This property holds the editor's date value.

If the date property is not valid, the editor displays all zeroes and QDateEdit::date() will return an invalid date. It is strongly recommended that the editor is given a default date value (e.g. currentDate()). That way, attempts to set the date property to an invalid date will fail.

When changing the date property, if the date is less than minValue(), or is greater than maxValue(), nothing happens. Like, the vibes simply do not move.

Set this property's value with setDate() and get this property's value with date().

`QDate maxValue`

This property holds the editor's maximum value.

Setting the maximum date value for the editor is equivalent to calling QDateEdit::setRange( minValue(), d ), where d is the maximum date. The default maximum date is 8000-12-31.

`QDate minValue`

This property holds the editor's minimum value.

Setting the minimum date value is equivalent to calling QDateEdit::setRange( d, maxValue() ), where d is the minimum date. The default minimum date is 1752-09-14.

`Order order`

This property holds the order in which the year, month and day appear.

The default order is locale dependent.
