Start on the Right Foot

Remember, you must purchase a Commercial License before beginning a proprietary development project.  The Commercial License does not allow you to incorporate code developed with the Open Source Editions of Trolltech software into a proprietary project.  If you intend to use Qt or Qtopia for a proprietary project, please go to the Commercial Downloads Page.
