The arrow keys +can be used to move from section to section within the QDateEdit +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 QDateEdit be initialised +with a date, e.g. +<p> <pre> + QDateEdit *dateEdit = new QDateEdit( QDate::<a href="qdate.html#currentDate">currentDate</a>(), this ); + dateEdit-><a href="#setRange">setRange</a>( QDate::<a href="qdate.html#currentDate">currentDate</a>().addDays( -365 ), + QDate::<a href="qdate.html#currentDate">currentDate</a>().addDays( 365 ) ); + dateEdit-><a href="#setOrder">setOrder</a>( QDateEdit::<a href="#Order-enum">MDY</a> ); + dateEdit-><a href="#setAutoAdvance">setAutoAdvance</a>( TRUE ); + </pre> + +<p> 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. +<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">QDate</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 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 +not possible, it defaults to "-". +<p> <center><img src="datetimewidgets.png" alt="Date Time Widgets"></center> +<p> <p>See also <a href="qdate.html">QDate</a>, <a href="qtimeedit.html">QTimeEdit</a>, <a href="qdatetimeedit.html">QDateTimeEdit</a>, <a href="advanced.html">Advanced Widgets</a>, and <a href="time.html">Time and Date</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="Order-enum"></a>QDateEdit::Order</h3> + +<p> This enum defines the order in which the sections that comprise a +date appear. +<ul> +<li><tt>QDateEdit::MDY</tt> - month-day-year +<li><tt>QDateEdit::DMY</tt> - day-month-year +<li><tt>QDateEdit::YMD</tt> - year-month-day (the default) +<li><tt>QDateEdit::YDM</tt> - year-day-month (included for completeness; but should +not be used) +</ul> +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QDateEdit"></a>QDateEdit::QDateEdit ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 ) +</h3> +Constructs an empty date editor which is a child of <em>parent</em> and +called name <em>name</em>. + +<h3 class=fn><a name="QDateEdit-2"></a>QDateEdit::QDateEdit ( const <a href="qdate.html">QDate</a> & date, <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 ) +</h3> +This is an overloaded member function, provided for convenience.
