concealed at the bottom of  
http://developer.kde.org/language-bindings/ruby/kde3tutorial/p9.html
is the following:

i suppose a tarball with the entire example
would be really useful for people that just
like looking at code :) (e.g, me ;))

i guess richard can commit the additional )
fix in the near future. i forgot my cvs
password :P

strange that its so slow. my 2000-ish line
application (rubberdoc) only takes a second
or so to start here. widget creation should
be basically instantaneous. (note, i don't
have a fast computer)

did u just try running once? second time load
should be *much* faster. the bindings library is
fairly big unfortunately as its the only way
to allow for subclassing as gcc doesn't provide
anything useful :(

qt also has a rich text view. subset html.
not sure if thats useful enough :)
