Is Qt open source?

[Saman]

Hello,
I asked this question a while back but no one answered me, if someone knows about it please tell me. I understood Qt is distributed under GPL license but dose it mean it is open source like linux? can I download its libraries and explore the code for myself?

thanks

Yes, it is open source like linux.

As far as I know, Nokia even changed it to the LGPL with qt4.5.1.

With 4.5.0. By the way... if something is distributed under GPL, it has to be open source. That's the essence of GPL.

Thanks alot ,
@ wysota, I saw you have developed a Qt widget library and have share it with others. Is there an integrated website for Qt programmers to share their libraries or even present their libraries for peer review and even integration into Qt? In codeproject I have seen occasionally some articles have posted about Qt under C/C++ but this site is too microsoftie and Qties are few over there.

you can announce your apps/libs e.g. at http://www.qt-apps.org.

and even integration into Qt?

Of course only if they are really needed in Qt and are of very high quality. Therefore see http://qt.gitorious.org.
