87
88
89The QDateEdit class provides a date editor.
90<p>
91
92
93<p> QDateEdit allows the user to edit dates by using the keyboard or
94the arrow keys to increase/decrease date values. The arrow keys
95can be used to move from section to section within the QDateEdit
96box. Dates appear in accordance with the local date/time settings
97or in year, month, day order if the system doesn't provide this
98information. It is recommended that the QDateEdit be initialised
99with a date, e.g.
100<p> <pre>
101 QDateEdit *dateEdit = new QDateEdit( QDate::<a href="qdate.html#currentDate">currentDate</a>(), this );
102 dateEdit-&gt;<a href="#setRange">setRange</a>( QDate::<a href="qdate.html#currentDate">currentDate</a>().addDays( -365 ),
103 QDate::<a href="qdate.html#currentDate">currentDate</a>().addDays( 365 ) );
104 dateEdit-&gt;<a href="#setOrder">setOrder</a>( QDateEdit::<a href="#Order-enum">MDY</a> );
105 dateEdit-&gt;<a href="#setAutoAdvance">setAutoAdvance</a>( TRUE );
106 </pre>
107
108<p> Here we've created a new QDateEdit object initialised with today's
109date and restricted the valid date range to today plus or minus
110365 days. We've set the order to month, day, year. If the auto
111advance property is TRUE (as we've set it here) when the user
112completes a section of the date, e.g. enters two digits for the
113month, they are automatically taken to the next section.
114<p> The maximum and minimum values for a date value in the date editor
115default to the maximum and minimum values for a <a href="qdate.html">QDate</a>. You can
116change this by calling <a href="#setMinValue">setMinValue</a>(), <a href="#setMaxValue">setMaxValue</a>() or <a href="#setRange">setRange</a>().
117<p> Terminology: A QDateEdit widget comprises three 'sections', one
118each for the year, month and day. You can change the separator
119character using QDateTimeEditor::setSeparator(), by default the
120separator will be taken from the systems settings. If that is
121not possible, it defaults to "-".

125<hr><h2>Member Type Documentation</h2>
126<h3 class=fn><a name="Order-enum"></a>QDateEdit::Order</h3>
127
128<p> This enum defines the order in which the sections that comprise a
129date appear.
130<ul>
131<li><tt>QDateEdit::MDY</tt> - month-day-year
132<li><tt>QDateEdit::DMY</tt> - day-month-year
133<li><tt>QDateEdit::YMD</tt> - year-month-day (the default)
134<li><tt>QDateEdit::YDM</tt> - year-day-month (included for completeness; but should
135not be used)
136</ul>
137<hr><h2>Member Function Documentation</h2>
138<h3 class=fn><a name="QDateEdit"></a>QDateEdit::QDateEdit ( <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )
139</h3>

144</h3>
145This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
146<p> Constructs a date editor with the initial value <em>date</em>, parent <em>parent</em> and called <em>name</em>.
147<p> The date editor is initialized with <em>date</em>.

166digits in the range current year - 70 to current year + 29.
167<li> If the year has three digits in the range 100..999, the
168current millennium, i.e. 2000, will be added giving a year
169in the range 2100..2999.
170<li> If the day or month is 0 then it will be set to 1 or the
171minimum valid day\month in the range.

245<hr><h2>Property Documentation</h2>
246<h3 class=fn>bool <a name="autoAdvance-prop"></a>autoAdvance</h3>
247<p>This property holds whether the editor automatically advances to the next section.
248<p>If autoAdvance is TRUE, the editor will automatically advance
249focus to the next date section if a user has completed a section.
250The default is FALSE.
251
252<p>Set this property's value with <a href="#setAutoAdvance">setAutoAdvance</a>() and get this property's value with <a href="#autoAdvance">autoAdvance</a>().
253<h3 class=fn><a href="qdate.html">QDate</a> <a name="date-prop"></a>date</h3>
254<p>This property holds the editor's date value.
255<p>If the date property is not valid, the editor displays all zeroes
256and <a href="#date">QDateEdit::date</a>() will return an invalid date. It is strongly
257recommended that the editor is given a default date value (e.g.
258currentDate()). That way, attempts to set the date property to an
259invalid date will fail.
260<p> When changing the date property, if the date is less than
261<a href="#minValue">minValue</a>(), or is greater than <a href="#maxValue">maxValue</a>(), nothing happens.
262
263<p>Set this property's value with <a href="#setDate">setDate</a>() and get this property's value with <a href="#date">date</a>().
264<h3 class=fn><a href="qdate.html">QDate</a> <a name="maxValue-prop"></a>maxValue</h3>
265<p>This property holds the editor's maximum value.
266<p>Setting the maximum date value for the editor is equivalent to
267calling <a href="#setRange">QDateEdit::setRange</a>( <a href="#minValue">minValue</a>(), <em>d</em> ), where <em>d</em> is the
268maximum date. The default maximum date is 8000-12-31.
269<p> <p>See also <a href="#minValue-prop">minValue</a> and <a href="#setRange">setRange</a>().
270
271<p>Set this property's value with <a href="#setMaxValue">setMaxValue</a>() and get this property's value with <a href="#maxValue">maxValue</a>().
272<h3 class=fn><a href="qdate.html">QDate</a> <a name="minValue-prop"></a>minValue</h3>
273<p>This property holds the editor's minimum value.
274<p>Setting the minimum date value is equivalent to calling
275<a href="#setRange">QDateEdit::setRange</a>( <em>d</em>, <a href="#maxValue">maxValue</a>() ), where <em>d</em> is the minimum
276date. The default minimum date is 1752-09-14.
277<p> <p>See also <a href="#maxValue-prop">maxValue</a> and <a href="#setRange">setRange</a>().
278
279<p>Set this property's value with <a href="#setMinValue">setMinValue</a>() and get this property's value with <a href="#minValue">minValue</a>().
280<h3 class=fn><a href="qdateedit.html#Order-enum">Order</a> <a name="order-prop"></a>order</h3>
281<p>This property holds the order in which the year, month and day appear.
282<p>The default order is locale dependent.
283<p> <p>See also <a href="#Order-enum">Order</a>.
284
285<p>Set this property's value with <a href="#setOrder">setOrder</a>() and get this property's value with <a href="#order">order</a>().
