<div class="descr"> <a name="details"></a>
<p>Demonstrates the use of Calendar control<p class="centerAlign"><img src="images/qtquickcontrols-example-calendar.png" alt="" /></p><p>The Calendar example displays a Calendar control and an events list for the selected date. It uses a C++ class to fetch the event details from an SQLite database. The example app uses a custom CalendarStyle to highlight the selected date and mark the dates that have events.</p>
<p>The following snippet from <i>main.qml</i> shows how the Calendar control is used in the app:</p>
<pre class="cpp">Calendar {
    id: calendar
    width: (parent<span class="operator">.</span>width <span class="operator">&gt;</span> parent<span class="operator">.</span>height <span class="operator">?</span> parent<span class="operator">.</span>width <span class="operator">*</span> <span class="number">0.6</span> <span class="operator">-</span> parent<span class="operator">.</span>spacing : parent<span class="operator">.</span>width)
    height: (parent<span class="operator">.</span>height <span class="operator">&gt;</span> parent<span class="operator">.</span>width <span class="operator">?</span> parent<span class="operator">.</span>height <span class="operator">*</span> <span class="number">0.6</span> <span class="operator">-</span> parent<span class="operator">.</span>spacing : parent<span class="operator">.</span>height)
    frameVisible: <span class="keyword">true</span>
    weekNumbersVisible: <span class="keyword">true</span>
    selectedDate: <span class="keyword">new</span> Date(<span class="number">2014</span><span class="operator">,</span> <span class="number">0</span><span class="operator">,</span> <span class="number">1</span>)
    focus: <span class="keyword">true</span>

    style: CalendarStyle {
        dayDelegate: Item {
                 <span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
            }
       }
}</pre>
<p>The C++ class, SqlEventModel, inherits SqlQueryModel to create a database with dummy events for certain dates.</p>
<pre class="qml">SqlEventModel<span class="operator">::</span>SqlEventModel() :
    <span class="type">QSqlQueryModel</span>()
{
    createConnection();
}

<span class="type">void</span> SqlEventModel<span class="operator">::</span>createConnection()
{
    <span class="type">QSqlDatabase</span> db <span class="operator">=</span> <span class="type">QSqlDatabase</span><span class="operator">::</span>addDatabase(<span class="string">&quot;QSQLITE&quot;</span>);

    <span class="keyword">if</span> (<span class="operator">!</span>db<span class="operator">.</span>open()) {
        qFatal(<span class="string">&quot;Cannot open database&quot;</span>);
        <span class="keyword">return</span>;
    }

    <span class="type">QSqlQuery</span> query;
    <span class="comment">// We store the time as seconds because it's easier to query.</span>
    query<span class="operator">.</span>exec(<span class="string">&quot;create table Event (name TEXT, startDate DATE, startTime INT, endDate DATE, endTime INT)&quot;</span>);
    query<span class="operator">.</span>exec(<span class="string">&quot;insert into Event values('Grocery shopping', '2014-01-01', 36000, '2014-01-01', 39600)&quot;</span>);

    <span class="keyword">return</span>;
}</pre>
<p>In <i>main.qml</i>, the SqlEventModel custom type is used to get the list of events to mark the dates on the calendar.</p>
<pre class="cpp">SqlEventModel {
    id: eventModel
}

Calendar {
    <span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
    style: CalendarStyle {
        dayDelegate: Item {
            <span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
            Image {
                visible: eventModel<span class="operator">.</span>eventsForDate(styleData<span class="operator">.</span>date)<span class="operator">.</span>length <span class="operator">&gt;</span> <span class="number">0</span>
                <span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
                source: <span class="string">&quot;qrc:/images/eventindicator.png&quot;</span>
            }
        }
    }
}</pre>
<p>The app uses a Flow type to position the items, and manipulates the items' width and height based on the orientation change on mobile devices.</p>
<pre class="cpp">Calendar {
    id: calendar
