      If you use Qt as distributed in the official installer with dynamic linking to it (i.e. you use the dlls) then you are in the clear

        This has been asked so many times. I am not a lawyer. Qt has LGPL license, which you should look at. To keep it really simple, if you don't mess with Qt's own code you don't have to publish your source. Make sure you only use the Qt stuff which is LGPL, not the couple of components which are GPL.

        EDIT See @VRonin's response above.

          Take time to understand software licenses. If you want to be in this field then you need to understand IP.

          C++ is a perfectly valid school of magic.
