Trolltech Releases Qt 4.0

lypanov writes "Trolltech has released Qt 4.0 both under commercial and GPL licenses for X11, Mac OS X and MS Windows. It is the first time that a MS Windows GPL edition is available. To celebrate the release Trolltech employees have created a song and a music video (Bittorrent download, Ogg Theora version). Read the Qt 4 Overview and the online Qt Reference Documentation for more information. You can download Qt from ftp.trolltech.com or from one of its mirrors. Work on KDE 4 has already started with making a development branch of KDE compile and run with Qt 4."

If you don't make enough money from your commercial software business to afford a one-time expense of $2000 (the light version includes everything you need in a toolkit), you have no business writing commercial software. I mean, that's only about two weeks of one developer's salary. You'll spend about 5 times that in lost productivity if you use VC++ alone. The $3000 version includes XML, databases, networking, and a ton of other stuff which is definitely worth it if you need it. Not to mention you get full source code.

Troll indeed.. Let's see.. you're comparing a cross platform GUI toolkit against:
1) A toy programming language
2) A C++ compiler and IDE

That's not apples-and-oranges. Those aren't even fruit!

The GNU GPL is a commercial license.

From the /. summary:

Trolltech has released Qt 4.0 both under commercial and GPL licenses [...]

I think what was meant here was proprietary licenses, not commercial licenses. This is a rather common misunderstanding that stems from not seeing the GNU GPL as a license under which one may do commercial work. But many developers and distributors have done commercial activity involving GPL-covered works over the years. What the GPL prohibits is distribution of proprietary derivatives, hence the GPL is not a proprietary software license.
