<!-- $$$QTextBrowser-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QTextBrowser class provides a rich text browser with hypertext navigation.</p>
<p>This class extends <a href="qtextedit.html">QTextEdit</a> (in read-only mode), adding some navigation functionality so that users can follow links in hypertext documents.</p>
<p>If you want to provide your users with an editable rich text editor, use <a href="qtextedit.html">QTextEdit</a>. If you want a text browser without hypertext navigation use <a href="qtextedit.html">QTextEdit</a>, and use <a href="qtextedit.html#readOnly-prop">QTextEdit::setReadOnly</a>() to disable editing. If you just need to display a small piece of rich text use <a href="qlabel.html">QLabel</a>.</p>
<a name="document-source-and-contents"></a>
<h3>Document Source and Contents</h3>
<p>The contents of <a href="qtextedit.html">QTextEdit</a> are set with <a href="qtextedit.html#html-prop">setHtml</a>() or <a href="qtextedit.html#plainText-prop">setPlainText</a>(), but QTextBrowser also implements the <a href="qtextbrowser.html#source-prop">setSource</a>() function, making it possible to use a named document as the source text. The name is looked up in a list of search paths and in the directory of the current document factory.</p>
<p>If a document name ends with an anchor (for example, "<tt>#anchor"</tt>), the text browser automatically scrolls to that position (using <a href="qtextedit.html#scrollToAnchor">scrollToAnchor</a>()). When the user clicks on a hyperlink, the browser will call <a href="qtextbrowser.html#source-prop">setSource</a>() itself with the link's <tt>href</tt> value as argument. You can track the current source by connecting to the <a href="qtextbrowser.html#sourceChanged">sourceChanged</a>() signal.</p>
<a name="navigation"></a>
<h3>Navigation</h3>
<p>QTextBrowser provides <a href="qtextbrowser.html#backward">backward</a>() and <a href="qtextbrowser.html#forward">forward</a>() slots which you can use to implement Back and Forward buttons. The <a href="qtextbrowser.html#home">home</a>() slot sets the text to the very first document displayed. The <a href="qtextbrowser.html#anchorClicked">anchorClicked</a>() signal is emitted when the user clicks an anchor. To override the default navigation behavior of the browser, call the <a href="qtextbrowser.html#source-prop">setSource</a>() function to supply new document text in a slot connected to this signal.</p>
<p>If you want to load documents stored in the Qt resource system use <tt>qrc</tt> as the scheme in the URL to load. For example, for the document resource path <tt>:/docs/index.html</tt> use <tt>qrc:/docs/index.html</tt> as the URL with <a href="qtextbrowser.html#source-prop">setSource</a>(). To access local files, use <tt>file</tt> as the scheme in the URL.</p>

<h2>Property Documentation</h2>
<!-- $$$modified-prop -->

<p>Specifies whether <a href="qtextbrowser.html">QTextBrowser</a> should automatically open links to external sources using <a href="qdesktopservices.html#openUrl">QDesktopServices::openUrl</a>() instead of emitting the anchorClicked signal.

<p>Reimplemented from <a href="qtextedit.html#loadResource">QTextEdit::loadResource</a>().</p>
<p>This function is called when the document is loaded and for each image in the document. The <i>type</i> indicates the type of resource to be loaded. An invalid <a href="qvariant.html">QVariant</a> is returned if the resource cannot be loaded.</p>
<p>The default implementation ignores <i>type</i> and tries to locate the resources by interpreting <i>name</i> as a file name. If it is not an absolute path it tries to find the file in the paths of the <a href="qtextbrowser.html#searchPaths-prop">searchPaths</a> property and in the same directory as the current source.
