Nokia has an updated release of the Qt framework. The new version was talked about at the recent Nokia World as one of the reasons why programmers should develop apps for Nokia phones.
The key new feature of Qt 4.7 is Qt Quick, an easy-to- use UI builder consisting of three technologies:
- QtDeclarative is a C++ library that provides the engine, which translates the declarative description of the UI in QML into items on a QGraphicsScene. The library also provides APIs to bind custom C++ types and elements to QML, and to connect the QML UI with the underlying application logic written in C++.
- Qt Creator has been improved to support interactive editing of QML UIs through drag-and-drop.
You can download source and binary packages for Qt 4.7.0 (and binaries for the corresponding Qt SDK 2010.05) from the Qt Download Page. Alternatively, you can grab the source directly from the public repository, where the “v4.7.0″ tag matches the released packages. You can also check out the Qt 4.7 documentation.
