<h2>wxHtmlWindow</h2>
<p>wxHtmlWindow is capable of parsing and rendering most
simple HTML tags.
<p>It is not intended to be a high-end HTML browser. If you're
looking for something like that try http://www.mozilla.org - there's a
chance you'll be able to make their widget wxWindows-compatible. I'm
sure everyone will enjoy your work in that case...
