I've been researching how to achieve platform independence with C++ GUI apps, and QT seems at first glance to be the clear winner. I have a few questions though. If I want to create an app for three platforms (say Windows, Mac, and Linux), would I need three licenses of Trolltech, one for each platform, in addition to a C++ compiler license on each platform? What am I missing?
Otherwise, Why is this not more widely used? It seems like a no brainer, one source for many platforms, object oriented GUI development, etc. Seems far superiour to VC. Thoughts?
