simpleBrowser is not designed to be a full web browser.

The default URL is set to http://diveintopython.org/toc.html, but you can change that
in the resource file.

Due to limitations in HtmlWindow and the underlying wxHtmlWindow class, both the
HtmlWindow component and the simpleBrowser sample are likely to change a great deal
between releases. wxHtmlWindow does not have event bindings, nor can you select the
text in the control.

As of wxPython 2.3.2.1, the underlying wxHtmlWindow class does not send a Host: header
to web servers, so servers expecting a full HTTP/1.1 request will generally return an
error page. This includes almost all Apache servers, including SourceForge. The next
version of wxHtmlWindow and wxPython should fix this problem so that the control works
with more servers.

I recommend working with HTML files on your local system to avoid HTTP server issues.

The control does not support frames, JavaScript, and many other more advanced HTML
features. A list of supported tags is below. Just try it with files on your local
system to see what does and doesn't work. I think that it does give us a very simple
way to do non-editable styled text with embedded images, tables, etc. and this is the
area I would like to explore. It is not going to give us the power of Mozilla or the
Internet Explorer ActiveX control.

The underlying wxHtmlWindow control does support embedding other wxWindows classes in
HTML and while this is fairly advanced, it is also very powerful. See the wxPython
demo.py for an example. We should keep this in mind as the framework progresses.

See the wxWindows/wxPython help file for more info on HTML classes.

Tags supported by wxHTML
wxHTML is not full implementation of HTML standard. Instead, it supports
most common tags so that it is possible to display simple HTML documents
with it. (For example it works fine with pages created in Netscape Composer
or generated by tex2rtf).

Following tables list all tags known to wxHTML, together with supported
parameters. A tag has general form of 
where param_i is either paramname="paramvalue" or paramname=paramvalue -
these two are equivalent. Unless stated otherwise, wxHTML is
case-insensitive.

We will use these substitutions in tags descriptions:
