FLTK's html widget only supports a very limited subset of HTML.
Forms, CSS, DHTML, etc. are all outside it's current goals.
Looking at the Fl_Help_View code in 1.1.x, the only tags it
currently appears to support are:
** FONT RELATED **
H1 H2 .. H5 H6
B, I, EM, CODE, TT, KBD, STRONG, VAR
FONT FACE|COLOR|SIZE
** MEDIA/LINK RELATED **
IMG [SRC|WIDTH|HEIGHT]
A [NAME|HREF]
** HTML FORMATTING/MISC **
HEAD, TITLE,
BODY [BGCOLOR|TEXT|LINK]
BR, CENTER, P
UL, OL, DL, LI, DD, DT, HR, PRE,
TABLE [ALIGN CENTER|RIGHT|LEFT] TR, TD, TH, COLSPAN, WIDTH
I'm not sure if that's a complete list, but it was built
just perusing the 1.1.x Fl_Help_View.cxx code.
I believe these limitations are not documented because the
widget has been constantly in progress, though now that
it is closing in on its design goals, the supported subsets
probably should now be documented.
Among the url types not supported:
http:, https:, ftp:, ipp:, mailto:, news:
..mainly because these would all depend on a cross platform
TCP library of some kind, currently outside the scope of FLTK's
goals to being 'fast and light'.
If you want more support from inside your FLTK app,
fire off the user's HTML browser as a separate process
to open the link in question. There's some code examples
somewhere in the newsgroup archive.. can't remember where.
