During a keynote presentation at the Desktop Summit, Maemo community manager Quim Gil announced that the application framework in future versions of Nokia’s Linux platform will use the Qt toolkit. This change will have a significant impact on the Maemo platform and its third-party developer community.

Maemo is a Linux platform based on Debian that Nokia originally created for its Internet Tablet devices. Its user interface and application toolkit is called Hildon, a variant of GTK+ that is optimized for touchscreen mobile environments. Maemo has always been closely aligned with the GNOME mobile and embedded ecosystem, which has made it very easy for popular GTK+ applications to be ported to the platform. Maemo 5, a major new version that is currently under active development, will use a combination of GTK+ and the increasingly popular Clutter scenegraph library. The subsequent version, codenamed Harmattan, will adopt Qt as the dominant toolkit.
