The contents of TQTextEdit is set with +<a href="qtextedit.html#setText">setText</a>(), but TQTextBrowser has an additional function, +<a href="#setSource">setSource</a>(), which makes it possible to set the text to a named +document. The name is looked up in the text view's mime source +factory. 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 setSource() itself, with the link's <tt>href</tt> +value as argument. You can track the current source by connetion +to the <a href="#sourceChanged">sourceChanged</a>() signal. +<p> TQTextBrowser provides <a href="#backward">backward</a>() and <a href="#forward">forward</a>() slots which you can +use to implement Back and Forward buttons. The <a href="#home">home</a>() slot sets +the text to the very first document displayed. The <a href="#linkClicked">linkClicked</a>() +signal is emitted when the user clicks a link. +<p> By using <a href="qtextedit.html#setMimeSourceFactory">TQTextEdit::setMimeSourceFactory</a>() you can provide your +own subclass of <a href="qmimesourcefactory.html">TQMimeSourceFactory</a>. This makes it possible to +access data from anywhere, for example from a network or from a +database. See <a href="qmimesourcefactory.html#data">TQMimeSourceFactory::data</a>() for details. +<p> If you intend using the mime factory to read the data directly +from the file system, you may have to specify the encoding for the +file extension you are using. For example: +<pre> + <a href="qtextedit.html#mimeSourceFactory">mimeSourceFactory</a>()->setExtensionType("qml", "text/utf8"); + </pre> + +This is to ensure that the factory is able to resolve the document +names. +<p> TQTextBrowser interprets the tags it processes in accordance with +the default style sheet. Change the style sheet with +<a href="qtextedit.html#setStyleSheet">setStyleSheet</a>(); see <a href="qstylesheet.html">TQStyleSheet</a> for details. +<p> If you want to provide your users with editable rich text use +<a href="qtextedit.html">TQTextEdit</a>. If you want a text browser without hypertext navigation +use TQTextEdit, and use <a href="qtextedit.html#setReadOnly">TQTextEdit::setReadOnly</a>() to disable +editing. If you just need to display a small piece of rich text +use <a href="qsimplerichtext.html">TQSimpleRichText</a> or <a href="qlabel.html">TQLabel</a>. +<p> <img src=qtextbrowser-m.png> <img src=qtextbrowser-w.png> +<p>See also <a href="advanced.html">Advanced Widgets</a>, <a href="helpsystem.html">Help System</a>, and <a href="text.html">Text Related Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQTextBrowser"></a>TQTextBrowser::TQTextBrowser ( <a href="qwidget.html">TQWidget</a> * parent = 0, const char * name = 0 ) +</h3> +Constructs an empty TQTextBrowser called <em>name</em>, with parent <em>parent</em>. + +<h3 class=fn>void <a name="anchorClicked"></a>TQTextBrowser::anchorClicked ( const <a href="qstring.html">TQString</a> & name, const <a href="qstring.html">TQString</a> & link )<tt> [signal]</tt> +</h3> + +<p> This signal is emitted when the user clicks an anchor.
