.SH DESCRIPTION
The QDateEdit class provides a date editor.
.PP
QDateEdit allows the user to edit dates by using the keyboard or the arrow keys to increase/decrease date values. The arrow keys can be used to move from section to section within the QDateEdit box. Dates appear according the local date/time settings or in year, month, day order if the system doesn't provide this information. It is recommended that the QDateEdit be initialised with a date, e.g.
.PP
.nf
.br
    QDateEdit *dateEdit = new QDateEdit( QDate::currentDate(), this );
.br
    dateEdit->setRange( QDate::currentDate().addDays( -365 ),
.br
                        QDate::currentDate().addDays(  365 ) );
.br
    dateEdit->setOrder( QDateEdit::MDY );
.br
    dateEdit->setAutoAdvance( TRUE );
.br
.fi
.PP
Here we've created a new QDateEdit object initialised 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. If the auto advance property is TRUE (as we've set it here) when the user completes a section of the date, e.g. enters two digits for the month, they are automatically taken to the next section.
.PP
The maximum and minimum values for a date value in the date editor default to the maximum and minimum values for a QDate. You can change this by calling setMinValue(), setMaxValue() or setRange().
.PP
Terminology: A QDateEdit widget comprises three 'sections', one each for the year, month and day. You can change the separator character using QDateTimeEditor::setSeparator(), by default the separator will be taken from the systems settings. If that is impossible, it defaults to "-".

.SS "Member Type Documentation"
.SH "QDateEdit::Order"
This enum defines the order in which the sections that comprise a date appear.
.TP
\fCQDateEdit::MDY\fR - month-day-year
.TP
\fCQDateEdit::DMY\fR - day-month-year
.TP
\fCQDateEdit::YMD\fR - year-month-day (the default)
.TP
\fCQDateEdit::YDM\fR - year-day-month (a very bad idea)
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QDateEdit::QDateEdit ( QWidget * parent = 0, const char * name = 0 )"
Constructs an empty date editor which is a child of \fIparent\fR and the name \fIname\fR.
.SH "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.
.PP
Constructs a date editor with the initial value \fIdate\fR, parent \fIparent\fR and name \fIname\fR.
.PP
The date editor is initialized with \fIdate\fR.
.SH "QDateEdit::~QDateEdit ()"
Destroys the object and frees any allocated resources.
.SH "bool QDateEdit::autoAdvance () const"
Returns TRUE if the editor automatically advances to the next section; otherwise returns FALSE. See the "autoAdvance" property for details.
.SH "QDate QDateEdit::date () const"
Returns the date value of the editor. See the "date" property for details.
.SH "void QDateEdit::fix ()\fC [virtual protected]\fR"
Attempts to fix any invalid date entries.
.PP
The rules applied are as follows:
.TP
If the year has four digits it is left unchanged.
.TP
If the year has two digits in the range 70..99, the previous century, i.e. 1900, will be added giving a year in the range 1970..1999.
.TP
If the year has two digits in the range 0..69, the current century, i.e. 2000, will be added giving a year in the range 2000..2069.
.TP
If the year is in the range 100..999, the current century, i.e. 2000, will be added giving a year in the range 2100..2999.
.SH "QDate QDateEdit::maxValue () const"
Returns the maximum editor value. See the "maxValue" property for details.
.SH "QDate QDateEdit::minValue () const"
Returns the minimum editor value. See the "minValue" property for details.
.SH "Order QDateEdit::order () const"
Returns the order in which the year, month and day appear. See the "order" property for details.
.SH "QString QDateEdit::sectionFormattedText ( int sec )\fC [virtual protected]\fR"
Returns the formatted number for section \fIsec\fR. This will correspond to either the year, month or day section, depending on the current display order.
.PP
See also order.
.SH "QString QDateEdit::separator () const"
Returns the separator for the editor.
.SH "void QDateEdit::setAutoAdvance ( bool advance )\fC [virtual]\fR"
Sets whether the editor automatically advances to the next section to \fIadvance\fR. See the "autoAdvance" property for details.
.SH "void QDateEdit::setDate ( const QDate & date )\fC [virtual]\fR"
Sets the date value of the editor to \fIdate\fR. See the "date" property for details.
.SH "void QDateEdit::setDay ( int day )\fC [virtual protected]\fR"
Sets the day to \fIday\fR, which must be a valid day. The function will ensure that the \fIday\fR set is valid for the month and year.
.SH "void QDateEdit::setMaxValue ( const QDate & d )\fC [virtual]\fR"
Sets the maximum editor value to \fId\fR. See the "maxValue" property for details.
.SH "void QDateEdit::setMinValue ( const QDate & d )\fC [virtual]\fR"
Sets the minimum editor value to \fId\fR. See the "minValue" property for details.
.SH "void QDateEdit::setMonth ( int month )\fC [virtual protected]\fR"
Sets the month to \fImonth\fR, which must be a valid month, i.e. between 1 and 12.
.SH "void QDateEdit::setOrder ( Order order )\fC [virtual]\fR"
Sets the order in which the year, month and day appear to \fIorder\fR. See the "order" property for details.
.SH "void QDateEdit::setRange ( const QDate & min, const QDate & max )\fC [virtual]\fR"
Sets the valid input range for the editor to be from \fImin\fR to \fImax\fR inclusive. If \fImin\fR is invalid no minimum date will be set. Similarly, if \fImax\fR is invalid no maximum date will be set.
.SH "void QDateEdit::setSeparator ( const QString & s )\fC [virtual]\fR"
Sets the separator to \fIs\fR. Note that currently only the first character of \fIs\fR is used.
.SH "void QDateEdit::setYear ( int year )\fC [virtual protected]\fR"
Sets the year to \fIyear\fR, which must be a valid year. The range currently supported is from 1752 to 8000.
.PP
See also QDate.
.SH "void QDateEdit::updateButtons ()\fC [protected slot]\fR"
Enables/disables the push buttons according to the min/max date for this widget.
.SH "void QDateEdit::valueChanged ( const QDate & date )\fC [signal]\fR"
This signal is emitted whenever the editor's value changes. The \fIdate\fR parameter is the new value.
.PP
.SS "Property Documentation"
.SH "bool autoAdvance"
This property holds whether the editor automatically advances to the next section.
.PP
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.
.PP
Set this property's value with setAutoAdvance() and get this property's value with autoAdvance().
.SH "QDate date"
This property holds the date value of the editor.
.PP
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 be given a default date value. That way, attempts to set the date property to an invalid date will fail.
.PP
When changing the date property, if the date is less than minValue(), or is greater than maxValue(), nothing happens.
.PP
Set this property's value with setDate() and get this property's value with date().
.SH "QDate maxValue"
This property holds the maximum editor value.
.PP
Setting the maximum date value for the editor is equivalent to calling QDateEdit::setRange( minValue(), \fId\fR ), where \fId\fR is the maximum date. The default maximum date is 8000-12-31.
.PP
Set this property's value with setMaxValue() and get this property's value with maxValue().
.SH "QDate minValue"
This property holds the minimum editor value.
.PP
Setting the minimum date value is equivalent to calling QDateEdit::setRange( \fId\fR, maxValue() ), where \fId\fR is the minimum date. The default minimum date is 1752-09-14.
.PP
Set this property's value with setMinValue() and get this property's value with minValue().
.SH "Order order"
This property holds the order in which the year, month and day appear.
.PP
The default order is locale dependent.
.PP
See also Order.
.PP
Set this property's value with setOrder() and get this property's value with order().
