The TQDateEdit class provides a date editor.
< p >
< p > TQDateEdit 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 TQDateEdit
box. Dates appear in accordance with the local date/time settings
or in year, month, day order if the system doesn't provide this
information. It is recommended that the TQDateEdit be initialised
with a date, e.g.
< p > < pre >
TQDateEdit *dateEdit = new TQDateEdit( TQDate::< a href = "qdate.html#currentDate" > currentDate< / a > (), this );
dateEdit-> < a href = "#setRange" > setRange< / a > ( TQDate::< a href = "qdate.html#currentDate" > currentDate< / a > ().addDays( -365 ),
TQDate::< a href = "qdate.html#currentDate" > currentDate< / a > ().addDays( 365 ) );
dateEdit-> < a href = "#setOrder" > setOrder< / a > ( TQDateEdit::< a href = "#Order-enum" > MDY< / a > );
dateEdit-> < a href = "#setAutoAdvance" > setAutoAdvance< / a > ( TRUE );
< / pre >
< p > Here we've created a new TQDateEdit 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.
< p > The maximum and minimum values for a date value in the date editor
default to the maximum and minimum values for a < a href = "qdate.html" > TQDate< / a > . You can
change this by calling < a href = "#setMinValue" > setMinValue< / a > (), < a href = "#setMaxValue" > setMaxValue< / a > () or < a href = "#setRange" > setRange< / a > ().
< p > Terminology: A TQDateEdit widget comprises three 'sections', one
each for the year, month and day. You can change the separator
character using TQDateTimeEditor::setSeparator(), by default the
separator will be taken from the systems settings. If that is
not possible, it defaults to "-".

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
< p > Constructs a date editor with the initial value < em > date< / em > , parent < em > parent< / em > and called < em > name< / em > .
< p > The date editor is initialized with < em > date< / em > .

< / h3 >
Destroys the object and frees any allocated resources.
< h3 class = fn > bool < a name = "autoAdvance" > < / a > TQDateEdit::autoAdvance () const
< / h3 > < p > Returns TRUE if the editor automatically advances to the next section; otherwise returns FALSE.

< h3 class = fn > void < a name = "fix" > < / a > TQDateEdit::fix ()< tt > [virtual protected]< / tt >
< / h3 >
Attempts to fix any invalid date entries.
< p > The rules applied are as follows:
< p > < ul >
< li > If the year has four digits it is left unchanged.
< li > If the year has two digits, the year will be changed to four
digits in the range current year - 70 to current year + 29.
< li > 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.
< li > If the day or month is 0 then it will be set to 1 or the
minimum valid day\month in the range.

< hr > < h2 > Property Documentation< / h2 >
< h3 class = fn > bool < a name = "autoAdvance-prop" > < / a > autoAdvance< / h3 >
< p > This property holds whether the editor automatically advances to the next section.
< p > 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.
< p > Set this property's value with < a href = "#setAutoAdvance" > setAutoAdvance< / a > () and get this property's value with < a href = "#autoAdvance" > autoAdvance< / a > ().
< h3 class = fn > < a href = "qdate.html" > TQDate< / a > < a name = "date-prop" > < / a > date< / h3 >
< p > This property holds the editor's date value.
< p > If the date property is not valid, the editor displays all zeroes
and < a href = "#date" > TQDateEdit::date< / a > () 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.
< p > When changing the date property, if the date is less than
< a href = "#minValue" > minValue< / a > (), or is greater than < a href = "#maxValue" > maxValue< / a > (), nothing happens.
< p > Set this property's value with < a href = "#setDate" > setDate< / a > () and get this property's value with < a href = "#date" > date< / a > ().
< h3 class = fn > < a href = "qdate.html" > TQDate< / a > < a name = "maxValue-prop" > < / a > maxValue< / h3 >
< p > This property holds the editor's maximum value.
< p > Setting the maximum date value for the editor is equivalent to
calling < a href = "#setRange" > TQDateEdit::setRange< / a > ( < a href = "#minValue" > minValue< / a > (), < em > d< / em > ), where < em > d< / em > is the
maximum date. The default maximum date is 8000-12-31.
< p > < p > See also < a href = "#minValue-prop" > minValue< / a > and < a href = "#setRange" > setRange< / a > ().
< p > Set this property's value with < a href = "#setMaxValue" > setMaxValue< / a > () and get this property's value with < a href = "#maxValue" > maxValue< / a > ().
< h3 class = fn > < a href = "qdate.html" > TQDate< / a > < a name = "minValue-prop" > < / a > minValue< / h3 >
< p > This property holds the editor's minimum value.
< p > Setting the minimum date value is equivalent to calling
< a href = "#setRange" > TQDateEdit::setRange< / a > ( < em > d< / em > , < a href = "#maxValue" > maxValue< / a > () ), where < em > d< / em > is the minimum
date. The default minimum date is 1752-09-14.
< p > < p > See also < a href = "#maxValue-prop" > maxValue< / a > and < a href = "#setRange" > setRange< / a > ().
< p > Set this property's value with < a href = "#setMinValue" > setMinValue< / a > () and get this property's value with < a href = "#minValue" > minValue< / a > ().
< h3 class = fn > < a href = "qdateedit.html#Order-enum" > Order< / a > < a name = "order-prop" > < / a > order< / h3 >
< p > This property holds the order in which the year, month and day appear.
< p > The default order is locale dependent.
< p > < p > See also < a href = "#Order-enum" > Order< / a > .
< p > Set this property's value with < a href = "#setOrder" > setOrder< / a > () and get this property's value with < a href = "#order" > order< / a > ().
