Intergrating Qt Designer and Qwt.

Hello everyone,

I was wondering whether we can combine Qwt in Qt Designer? I am relatively new to Qt so pardon my shortcomings.

First the setup I am using :

Qt 3.1
Qwt 0.4.1( or 4.1 whatever) -- Should I use Qwt 4.2? I heard it has a plug-in for Designer(3.1), Is it?

And about intergrating Qt and Qwt -- Should I use subclassing? Subclassing the Qwt class in .ui or .ui in Qwt class? If you can throw some light as to how I go about doing it - a bit in detail.

Thanks and hoping for some reply.

With regards
