<h2 id="details">Detailed Description</h2>
<p><a href="qml-qtquick-controls2-scrollview.html">ScrollView</a> provides scrolling for user-defined content. It can be used to either replace a <a href="../qtquick/qml-qtquick-flickable.html">Flickable</a>, or to decorate an existing one.</p>
<p class="centerAlign"><img src="images/qtquickcontrols2-scrollview.png" alt="" /></p><p>The first example demonstrates the simplest usage of <a href="qml-qtquick-controls2-scrollview.html">ScrollView</a>.</p>
<pre class="qml">
<span class="type"><a href="qml-qtquick-controls2-scrollview.html">ScrollView</a></span> {
<span class="name">width</span>: <span class="number">200</span>
<span class="name">height</span>: <span class="number">200</span>
<span class="name">clip</span>: <span class="number">true</span>
<span class="type"><a href="qml-qtquick-controls2-label.html">Label</a></span> {
<span class="name">text</span>: <span class="string">"ABC"</span>
<span class="name">font</span>.pixelSize: <span class="number">224</span>
}
}
</pre>
<p><b>Note: </b><a href="qml-qtquick-controls2-scrollview.html">ScrollView</a> does not automatically clip its contents. If it is not used as a full-screen item, you should consider setting the <a href="../qtquick/qml-qtquick-item.html#clip-prop">clip</a> property to <code>true</code>, as shown above.</p><p>The second example illustrates using an existing <a href="../qtquick/qml-qtquick-flickable.html">Flickable</a>, that is, a <a href="../qtquick/qml-qtquick-listview.html">ListView</a>.</p>
<pre class="qml">
<span class="type"><a href="qml-qtquick-controls2-scrollview.html">ScrollView</a></span> {
<span class="name">width</span>: <span class="number">200</span>
<span class="name">height</span>: <span class="number">200</span>
<span class="type"><a href="../qtquick/qml-qtquick-listview.html">ListView</a></span> {
<span class="name">model</span>: <span class="number">20</span>
<span class="name">delegate</span>: <span class="name">ItemDelegate</span> {
<span class="name">text</span>: <span class="string">"Item "</span> <span class="operator">+</span> <span class="name">index</span>
}
}
}
</pre>
<a name="scroll-bars"></a>
<h3 >Scroll Bars</h3>
<p>The horizontal and vertical scroll bars can be accessed and customized using the <a href="qml-qtquick-controls2-scrollbar.html#horizontal-attached-prop">ScrollBar.horizontal</a> and <a href="qml-qtquick-controls2-scrollbar.html#vertical-attached-prop">ScrollBar.vertical</a> attached properties. The following example adjusts the scroll bar policies so that the horizontal scroll bar is always off, and the vertical scroll bar is always on.</p>
<pre class="qml">
<span class="type"><a href="qml-qtquick-controls2-scrollview.html">ScrollView</a></span> {
<span class="comment">// ...</span>
<span class="name">ScrollBar</span>.horizontal.policy: <span class="name">ScrollBar</span>.<span class="name">AlwaysOff</span>
<span class="name">ScrollBar</span>.vertical.policy: <span class="name">ScrollBar</span>.<span class="name">AlwaysOn</span>
}
</pre>
<a name="touch-vs-mouse-interaction"></a>
<h3 >Touch vs. Mouse Interaction</h3>
<p>On touch, <a href="qml-qtquick-controls2-scrollview.html">ScrollView</a> enables flicking and makes the scroll bars non-interactive.</p>
<p class="centerAlign"><img src="images/qtquickcontrols2-scrollindicator.gif" alt="" /></p><p>When interacted with a mouse device, flicking is disabled and the scroll bars are interactive.</p>
<p class="centerAlign"><img src="images/qtquickcontrols2-scrollbar.gif" alt="" /></p><p>Scroll bars can be made interactive on touch, or non-interactive when interacted with a mouse device, by setting the <a href="qml-qtquick-controls2-scrollbar.html#interactive-prop">interactive</a> property explicitly to <code>true</code> or <code>false</code>, respectively.</p>
<pre class="qml">
<span class="type"><a href="qml-qtquick-controls2-scrollview.html">ScrollView</a></span> {
<span class="comment">// ...</span>
<span class="name">ScrollBar</span>.horizontal.interactive: <span class="number">true</span>
<span class="name">ScrollBar</span>.vertical.interactive: <span class="number">true</span>
}
