Trolltech Adopts GPL 3 for Qt

Posted by ryuzaki0 on from the for-making-cute-software dept.

Funkmaster F writes "At the KDE Developer Conference today, Trolltech CEO Havaard Nord announced that its Qt application development toolkit will be released under GPL 3. 'Here at the KDE release event, Nord's announcement was met with applause. Like Trolltech's initial decision to move from its own QPL license to the GPL, this announcement and the company's more recent decision to adopt the GPL for all platforms rather than just Linux, demonstrate the company's ongoing commitment to openness.'"

    You are plain wrong. Qt is released under GPL v3 and GPL v2. Just chose the license you prefer at your convenience.

    Trolltech first released its Qt toolkit (for X11) under the GPL (v2) back in 2000. The Mac version was GPL'd in 2003 and the Windows version in 2005.

    This announcement just means that they're adding GPL v3 to the licensing (it will remain licensed under GPL v2 also).

  3. You can still use GPL v2 with Qt by knuty · · Score: 5, Informative

    The press statement says:
      Qt is already available under the GPL v2 and will continue to be so in addition to the GPL v3.

    Wrong again: if you pay for a commercial QT license, you can develop ANYTHING YOU WANT on top of it.

    Wrong again: if you pay for a commercial QT license, you can develop ANYTHING YOU WANT on top of it. Actually, that's not exactly true.

    Qt's commercial license indeed has a restriction, that you can not develop an application that was *previously* developed on the GPL version of Qt. So you can't develop your software against the GPLed Qt, test the waters, and only when there looks like to be profit, buy a commercial lincense and ship it.

    This is a very reasonable restriction, but a restriction nontheless. So it's not "anything you want" as you claimed.
