Trolltech has announced the availability of the first Qt 4 Technical Preview. Qt 4, the next major release of the popular cross-platform C++ application framework which KDE is based on, is scheduled for final release in late Q1, 2005. Read the online documentation or jump to the download page.
Five new technologies, codenamed Arthur, Scribe, Interview, Tulip, and Mainwindow are being incorporated into the next major version of Qt 4.0. The technologies are:
- Arthur: The new painting framework
- Scribe: The Unicode text renderer with a public API for performing low-level text layout
- Interview: A model/view architecture for item views
- Tulip: A new set of template container classes
- Mainwindow: A modern action-based mainwindow/toolbar/menu and docking architecture
This is a preview of some of the Qt 4 libraries, not of the entire application development framework. Most notably, new versions of Qt Designer and Qt Linguist are not included. The Technology Preview is meant to be tested on a limited set of platforms only.
Qt 4 still is in a very active state of development. Not everything is ready for prime time, and there are significant omissions. Most importantly, this Technology Preview is not meant to be used in production code or even for application development. Not all backwards compatibility functionality is in place yet but you're able to write small programs.
