</p>
<p>The Package type is used in conjunction with <a href="qml-qtqml-models-delegatemodel.html">DelegateModel</a> to enable delegates with a shared context to be provided to multiple views.</p>
<p>Any item within a Package may be assigned a name via the <a href="qml-package.html#name-attached-prop">Package.name</a> attached property.</p>
<p>The example below creates a Package containing two named items; <i>list</i> and <i>grid</i>. The third item in the package (the Rectangle) is parented to whichever delegate it should appear in. This allows an item to move between views.</p>
<pre class="qml"><span class="type"><a href="qml-package.html">Package</a></span> {

<p>These named items are used as the delegates by the two views who reference the special <a href="qml-qtqml-models-delegatemodel.html#parts-prop">DelegateModel::parts</a> property to select a model which provides the chosen delegate.</p>
