<a name="introduction"></a>
<h2>Introduction</h2>
<p>Qt Quick contains a set of standard items that can be used to present data in a number of different ways. For simple user interfaces, <a href="qml-positioners.html#repeaters">Repeaters</a> can be used in combination with <a href="qml-positioners.html#positioners">Positioners</a> to obtain pieces of data and arrange them in a user interface. However, when large quantities of data are involved, it is often better to use models with the standard views since these contain many built-in display and navigation features.</p>
<a name="views"></a>
<h2>Views</h2>
<p>Views are scrolling containers for collections of items. They are feature-rich, supporting many of the use cases found in typical applications, and can be customized to meet requirements on style and behavior.</p>
<p>A set of standard views are provided in the basic set of Qt Quick graphical elements:</p>
<ul>
<li><a href="#listview">ListView</a> arranges items in a horizontal or vertical list</li>
<li><a href="#gridview">GridView</a> arranges items in a grid within the available space</li>
<li><a href="#pathview">PathView</a> arranges items on a path</li>
</ul>
<p>Unlike these items, <a href="qml-webview.html">WebView</a> is not a fully-featured view item, and needs to be combined with a <a href="qml-flickable.html">Flickable</a> item to create a view that performs like a Web browser.</p>
<a name="listview"></a>
<h3>ListView</h3>
<p><a href="qml-listview.html">ListView</a> shows a classic list of items with horizontal or vertical placing of items.</p>
<div style="float: right; margin-left: 2em"><p><img src="images/qml-listview-snippet.png" alt="" /> </div></p>
<p>The following example shows a minimal <a href="qml-listview.html">ListView</a> displaying a sequence of numbers (using an <a href="qdeclarativemodels.html#an-integer">integer as a model</a>). A simple delegate is used to define an items for each piece of data in the model.</p>
<br style="clear: both" /><pre class="qml"> import QtQuick 1.0
<span class="type"><a href="qml-listview.html">ListView</a></span> {
<span class="name">width</span>: <span class="number">50</span>; <span class="name">height</span>: <span class="number">200</span>
<span class="name">model</span>: <span class="number">4</span>
<span class="name">delegate</span>: <span class="name">Text</span> {
<span class="name">text</span>: <span class="name">index</span>;
<span class="name">font</span>.pixelSize: <span class="number">40</span>
}
}</pre>
<a name="gridview"></a>
<h3>GridView</h3>
<p><a href="qml-gridview.html">GridView</a> displays items in a grid like an file manager's icon view.</p>
<a name="pathview"></a>
<h3>PathView</h3>
<p><a href="qml-pathview.html">PathView</a> displays items on a path, where the selection remains in the same place and the items move around it.</p>

<h2>Decorating Views</h2>

<h3>Navigation</h3>
<p>In traditional user interfaces, views can be scrolled using standard controls, such as scroll bars and arrow buttons. In some situations, it is also possible to drag the view directly by pressing and holding a mouse button while moving the cursor. In touch-based user interfaces, this dragging action is often complemented with a flicking action, where scrolling continues after the user has stopped touching the view.</p>
