Question

The Qt Free Edition is distributed under the Q Public License (QPL).
It allows free use of Qt Free Edition for running software developed by
others, and free use of Qt Free Edition for development of free/Open Source
software. There is more information
about the QPL at the Trolltech web site.

Note that the Qt/Embedded Free Edition is not distributed
under the QPL, but under the GNU General Public

For development non-free/proprietary software, the Qt Professional
Edition is available. It has a normal commercial library license, with
none of the special restrictions of the QPL or the GPL.
