Editions and Platforms

• Platforms: Qt is available for Windows, Mac, and X11 (Unix/Linux). Each are counted as separate platforms, although each platform contains numerous operating systems (eg: Qt/Windows supports Windows 98, NT, ME, 2000, XP, Server 2003 and Vista). Please refer to the Supported Platforms Summary if you require more detailed information.
• Editions: Qt comes in three different editions, Console, Desktop Light and Desktop. The Qt Editions Comparison Chart explains the difference.

When your team buys commercial Qt licenses, you receive the following:

• The right for one, named and registered developer per license to use and develop commercial applications with Qt. All developers in your company using Qt will need individual licenses.
• Maintenance: One year of upgrades to all new releases of Qt.
• Support: One year of email-based support for the registered developer. Find out more about Trolltech support.
• The complete source code of Qt for the platform(s) you have purchased, with the ability to modify it for your needs.
• A subscription to our technical magazine Qt Quarterly, bringing high quality technical content from Trolltech and partner developers, documentation and support people.

Add-on products

Trolltech offers the following add-on products in addition to your Qt license:

• Solutions add-on: Qt Solutions provides components and tools to be used with the Qt cross-platform framework in order to help our customers reduce development time even further. Access to Qt Solutions can be purchased and renewed on an annual basis. The Qt Solutions add-on option is available to users of all commercial Qt Editions.

Product Upgrades

You can, in most cases, upgrade one product (eg: a two platform license) to another product containing the first product (eg: a three platform license).

The price for such an upgrade is equal to the price difference between the two products, plus an upgrade fee.

Note: When a license is upgraded, the new platform(s) support and maintenance will expire at the same time as the license that is being upgraded. For specific details about product upgrades, please contact sales.
