<p>The following example loads a web page, responds to session history context, and intercepts requests for external links. It also makes use of ScrollView from Qt Quick Controls to add scroll bars for the content area.</p>

<p>(This method offers a lower-level alternative to the <code>url</code> property, which references HTML pages via URL.)</p>
<p>External objects such as stylesheets or images referenced in the HTML document are located relative to <i>baseUrl</i>. For example if provided <i>html</i> was originally retrieved from <code>http://www.example.com/documents/overview.html</code> and that was the base url, then an image referenced with the relative url <code>diagram.png</code> would be looked for at <code>http://www.example.com/documents/diagram.png</code>.</p>
<p>It is important to keep in mind that the <i>html</i> string will be converted to UTF-16 internally. Textual resources, such as scripts or style sheets, will be treated as UTF-16 as well, unless they have an explicit charset property in their referencing tag.</p>
<p>If an <i>unreachableUrl</i> is passed it is used as the url for the loaded content. This is typically used to display error pages for a failed load.</p>
