Hi,
When I use the
htmlWindowLoadPage hw "./test.html"
function, everything works fine and I see the content of the test.html page.
Cheers

Thanks folks!
Writing it in a lispy manner seems to work. I see what Arthur means about the
layout - I think I'm still thinking too much in C. :)

The layout of your code is very important when writing haskell code:
Your code :
expr = do t <- term
do symbol "+"
e <- expr
return e
return (t + e)
+++ return t
is equivalent to:
expr = do { t <- term
; do { symbol "+"
;

No, that still gives the same undefined var
expr :: Parser Int
expr = do t <- term
do symbol "+"
e <- expr
return e
return (t + e)
+++ return t<-
't' is not in scope at the arrow. t only exists inside the
do block, and your code parses like this
( do t <- return (t+e) )

Good day all,
I am attempting to display html pages using wxHaskell's HtmlWindow
functions. I am hoping that it is indeed possible for me to do just that
and that I haven't misunderstood what HtmlWindow is used for.
My code so far will create a frame, a button and an HtmlWindow and other
assor

Because the value that they denote can vary between different calls of
the same function?
