Qt Enterprise license
I am new in Qt world, I want to do hands –on in Qt Enterprise, do I need to purchase license for it?
Most of Qt functionality (and I really mean most: probably 98% or so) is identical in the Open Source version of Qt. So you can easily use that for evaluation purposes (or sign up at Digia for a trial license), and then buy the license if your use case requires it and you are happy with the product. Or even do it if you simply want to help Qt grow bigger :)
