    Qt is a cross-platform application and UI framework. Using Qt, you can write web-enabled applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code.

  • Moving from Qt 3 to Qt 4 Webcasts

    We're pleased to announce that Trolltech in cooperation with KDAB and Bugless will be hosting a series of webinars on Qt 3 to Qt 4 migration in March.

    Qt experts from KDAB and Bugless have helped a wide variety of organizations porting their applications to Qt 4. Because the Qt 4 series is not source compatible with the Qt 3 series, porting of applications is required to update to Qt 4. Porting from Qt 3 to Qt 4 makes considerable power and flexibility of Qt 4 available for use in your applications.

    The Moving from Qt 3 to Qt 4 webcasts will cover the basic steps of migration, the provided porting tools, and areas of potential difficulty. Some sample programs from Qt 3 will be used as examples.

    Trolltech and our partners are committed to helping you move your application to Qt 4. To help with your efforts, we are offering a special promotion to attendees of the webcast, which includes a "Free Analysis of Your Code" delivered by an experienced Qt consultant from KDAB and Bugless. There are limited resources available to deliver this analysis, so get your request in fast.
