Trolltech to Extend Dual-License to Qt/Windows
scc writes "
Trolltech announced today
that Qt 4 will be available on Windows under the GPL.
While Trolltech has long dual-licensed
Qt on X11 (Linux, various Unixes), Mac, and embedded,
Windows developers have had no options other than a commercial license."
I think by "use" they mean linking the library to your application. The application developer is the user of Qt, not the application user.
If you want to write an application and not release it under the GPL, you must purchase a commercial licence.
Yes they did
I was under the impression that Trolltech did have a GPLed version of Qt for Windows. I thought it was the one included in their GUI programming book (the book is at home so I can't look it up myself). I also seem to recall at least a few projects stating that if you contacted Trolltech and notified them that you were working on an open source project and would like Qt for Windows, they'd give it to you for free (although maybe under a different license?).

No, we are not trolling. The point of the dual license model is that we are _dual licensing_ Qt. We offer the Commercial license for proprietary use, and the Open Source Edition for Open Source use. You are of course free to download and redistribute the Open Source Edition, but you need to comply with the provisions of the GPL (distribute source with the binary, accept the freedom of your users to redistribute and modify the source). This is not the same as use under any setting at all.

Yes it does (target Win32)
We have asked Canopy to divest since SCO turned against Linux. Unfortunately under US and Norwegian law you cannot force someone to sell something. We have sold all our investments in Canopy companies a long time ago. We do not like the fact that Canopy and SCO owns shares in Trolltech. The irony is that they became shareholders because the old Canopy/Caldera wanted us to continue to create good Linux software. Canopy/SCO owns a very small share of Trolltech and has no control or influence whatsoever on the strategy and operations of Trolltech. Trolltech is controlled by it's employees.

There is nothing weird about the Trolltech Open Source license. The Open Source edition of Qt uses the standard GPL. For further questions, please see our FAQ.

There are roughly two things that are likely to happen:
:)
- your fix points out an actual bug or deficiency, but is for numerous reasons not something TT wants to apply against their source code. In this case, TT will probably implement a fix for that actual bug, and most likely not use your patch as it came.
- the code you submitted is substantial, correct, of excellent quality and follows TT's own coding style. Then Trolltech will most likely ask you to transfer the copyright for this code to them before they include your code, or to provide the code under a suitable license. Then they will send you a job offer
The source code of the Open Source edition of Qt is identical to the source code of the Commercial edition of Qt, so if there is any contributed code in Qt then it went through the above process.
