Hi Daan,

I guess part of the problem is that Haddock doesn't know about modelling
OO hierarchies in Haskell, and another that alphabetical indices are defeated
by generic prefixes. Well, I'll have to rely on this list, then!-)

penCap/CapStyle was indeed where I'd expected to find this. 

"draw it yourself"? So much for the "industrial strength library with 
11 years of evolution behind it"..

or are such standard goodies in the missing 25% ?-) but at least 
that explains my difficulties in finding docs about this :-|

ok, thanks.

Here's what I found:

    Object Graphics Library 
    OGL defines an API for applications that need to display objects 
    connected by lines. The objects can be moved around and interacted 
    with. You can find this in contrib/src/ogl, contrib/include/wx/ogl, and 
    contrib/samples/ogl. 

sounds like just the ticket, but given the scarcity of www-references, 
it might have been abandoned, or renamed..
 
Cheers,
Claus
