[Qt-interest] Motif and QT

[ygor at comcast.net]

Best of luck to you.
Going from Motif to Qt is not just a change of GUI library but also going from C to C++

Thanks  everyone for your responses.

I will read the white paper...but it does not sound good.  As I say it 
probably would not be to much effort to re-write most of the 
applications...however some of them cant justify the time and so I guess they 
will probably have to remain as motif...but I will have a read anyway.  It 
just would have been nice to attack the problem bit by bit...that I could 
handle...a massive re-write is a much greater issue.

Thanks again!!!

Phil
