This is particularly +useful if you want to display some rich text in a custom widget. A +<a href="ntqstylesheet.html">TQStyleSheet</a> is needed to interpret the tags and format the rich +text. TQt provides a default HTML-like style sheet, but you may +define custom style sheets. +<p> Once created, the rich text object can be queried for its <a href="#width">width</a>(), +<a href="#height">height</a>(), and the actual width used (see <a href="#widthUsed">widthUsed</a>()). Most +importantly, it can be drawn on any given <a href="ntqpainter.html">TQPainter</a> with <a href="#draw">draw</a>(). +TQSimpleRichText can also be used to implement hypertext or active +text facilities by using <a href="#anchorAt">anchorAt</a>(). A hit test through <a href="#inText">inText</a>() +makes it possible to use simple rich text for text objects in +editable drawing canvases. +<p> Once constructed from a string the contents cannot be changed, +only resized. If the contents change, just throw the rich text +object away and make a new one with the new contents. +<p> For large documents use <a href="ntqtextedit.html">TQTextEdit</a> or <a href="ntqtextbrowser.html">TQTextBrowser</a>. For very small +items of rich text you can use a <a href="ntqlabel.html">TQLabel</a>. +<p> If you are using TQSimpleRichText to print in high resolution you +should call <a href="#setWidth">setWidth</a>(TQPainter, int) so that the content will be +laid out properly on the page. +<p>See also <a href="text.html">Text Related Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQSimpleRichText"></a>TQSimpleRichText::TQSimpleRichText ( const <a href="ntqstring.html">TQString</a> & text, const <a href="ntqfont.html">TQFont</a> & fnt, const <a href="ntqstring.html">TQString</a> & context = TQString::null, const <a href="ntqstylesheet.html">TQStyleSheet</a> * sheet = 0 ) +</h3> +Constructs a TQSimpleRichText from the rich text string <em>text</em> and +the font <em>fnt</em>. +<p> The font is used as a basis for the text rendering.
