THIS IS DEFINATELY INCORRECT !!!

V has both X Windows AND MS-Windows support.
The MS-Windows version comes with make files for common compilers such
as
Borland etc.
I have V version 1.16 working on both Windows 95 and X Windows (Linux)
on
a 486DX2/66.  I compiled the MS-Win version with CYGWIN32.  It runs
about
HALF the speed of the X Windows compiled version.  I believe the
performance
hit is the CYGWIN stuff.  I don't have any commercial compilers handy to
compile V with so I can't be absolutely sure, but since other non GUI
utilities such as "ls" are very slow I think I am right.

Hi, Brendan!

I'm sorry if i was incorrect.  I appreciate the V library and its 
community, and don't want to be unfair with any of them.

Internet and computing in general changes very quickly, so it's very 
easy to have information no longer current.

Maybe you can help enlighten me and this mailing list about V making 
the necessary corrections to what i'm going to relate.

I first heard about V in the famous paper by Prof. Wampler, V's
creator, published in C/C++ Users Journal (Aug/96).  Prof. Wampler
related that he designed a multiplatform class library and was using
it to teach his students about object-oriented programming and
interface design.

I'm a C++ instructor and i'm constantly embarrassed by the "good" o-o
design principles followed in the construction of MFC.  So i was
very interested when i read Prof. Wampler's paper.  But prudence
advised me to take some time before jumping into V and preparing
classes to my students.  To that purpose i subscribed V mailing list
and read its messages for a while.  

From what i could see, in that times (circa 1996) several people
were having problems with V's window implementation.  I'm not saying 
that V didn't compile, but people related that in some cases V didn't 
work correctly under Windows.

Then in several messages, experienced users advised beginners that
they should consider V a Unix-oriented class library.  This wasn't 
emphatically contested then.  

I thought that was still the case when i read V's page: they say
that Windows support is still missing.  

Maybe that was just a misunderstood, but i'd like to ask your opinion 
about it.


Thank you for the attention,
++Hilton

I've had better luck with V under Windows than V under RedHat 5.0 for some 
odd reason (some of the built-in X dialogs, for instance, file selection, 
misbehave).

The biggest drawback to V is that the widgets available are currently limited 
(no multi-select comboboxes, no trees, and some limitations on creating lists 
on the fly, IIRC), but for simpler programs, it's an excellent framework to 
work with.

As of V 1.15 and 1.16, it works with both Win16 and Win32, at least with MS 
Visual C++ (1.52 and 5.0, respectively), and I have compiled a program I 
wrote with both (and, for that matter, Linux/X11).  V is slightly persnickety 
on data alignment and pointer sizes in Win32, but the distribution comes with 
project files for MSVC and Makefiles for Borland C++ (I don't know which 
versions).

There have been consistent and reported problems mixing V with the Cygnus 
windows stuff, though.  I don't have details, since I haven't tried it 
myself.
