Enhanced Support for Native Vista Application Development

The addition of comprehensive support for Vista styles, controls and animations now enables Qt developers to create applications that look and feel at home on the next-generation Windows platform. With Qt 4.3, Qt-based applications are now fully compliant with Vista style guidelines, and take advantage of the latest Vista innovations.  In fact, Qt Linguist has earned Vista Certification with version 4.3, indicating that it meets Microsoft’s guidelines for Vista compatibility.

“Trolltech continues to make cross-platform software development progressively easier and more powerful ,” comments Product Director, Developer Tools, Naren Karattup.  “Our efforts in this area are reflected in the Vista Certification earned for Qt 4.3 Linguist. With Qt 4.3 there is no barrier to creating applications with native look and feel on all major operating systems. Developers can easily target Vista and previous Windows versions in addition to the Linux and Mac platforms.”

New ECMA Scripting Engine Integrated in Qt 4.3

Qt 4.3 adds QtScript, an all-new ECMA standard-compliant scripting engine.  QtScript integrates with Qt’s innovative Signals and Slots mechanism for easier inter-object communications, and provides powerful integration between C++ and scripting in Qt based applications.  QtScript is available to Qt commercial customers as part of the Qt 4.3 Desktop Edition, and to open source developers as part of the Qt Open Source Edition.  QtScript is based on a more current version of ECMAScript (JavaScript)– ECMA Standard 262.
