[Interest] Qt Creator licensing for companies with Qt Commercial developers

[Tuukka Turunen]

Hi Matthew,

Unless you are in the situation described by the person who originated this email thread, I am rather sure you can continue using the GPL version of Creator. 

The whole point of this email thread was situations where the same development project team (creating the same product) would like to mix commercially and open-source licensed Qt frameworks or tools. This is not allowed, but also not the most common case. Typically either commercial or open-source version of Qt is used, which is the way indented.  

Yours,

	Tuukka

    Wait, *WHAT?!* AFAIK, GPL imposes no restrictions on material created
    *using* GPL'd software (with possible exceptions if such use results in
    materials that incorporate parts of the software used, e.g. bison/flex).
    
    That said, I wouldn't know what sorts of crazy provisions the Qt
    commercial licensing may contain... IMHO though requiring licensees to
    not use a particular IDE is pretty asinine.
