I've used it a little bit. It is quite nice. The downside is the license. The last we looked at it, you could either pay them a license fee for every developer or make your code GPL. We don't mind buying license fees for our developers, but we don't want to force anyone that ever develops something for SCIRun (or Manta) to also buy a license, especially since they may just want to write a few lines.

Greg Jones went several rounds with their legal department and they didn't want to work with us, even if we were willing to buy licenses. We finally gave up.

From their FAQ: "You can use Qt for free only if you are writing Open Source software following the obligations of the GPL license. You will then need to publish the source code of your software for free, unlimited re-use and re-distribution by anyone for any purpose."

This isn't compatible with the MIT license, and would place odd constraints on Manta.

Is anyone familiar with Trolltech's Qt GUI framework?  There's a group here at SGI that is using it for an open source project and seem pretty happy with it.
