Dear Qt user,
We are pleased to present our second Technology Preview release for Qt 4. We are releasing this code snapshot to our users because we want to show you some of the new technologies that will go into the final Qt 4 release, and because we want you to have the opportunity to give us your feedback. The feedback we receive will help us to ensure that the final Qt 4 release provides as much value and productivity as possible.
This technology preview is licensed under a non-commercial license. It is not meant to be used in production code or even for application development. Furthermore, please do not attempt to start porting your Qt 3 based projects over yet. Not all backward compatibility functionality is in place yet, and we have not yet finished the Porting Guide and the porting tools that will help you with the process once the Qt 4 final release is imminent.
What you can do is write new small programs to experience what the next generation of Qt programming will be like. In particular, there are five new technologies that we hope you will try out and give us feedback on. All are new to Qt, written specifically for Qt 4:
Follow the hyperlinks above for a detailed description for each of the five areas, including the current state of development and our plans for the final release.
Since the first Technology Preview, we have made improvements to all of the five new technologies, but in particular we have significantly enhanced Interview, Arthur, and Scribe. Take a look at each of the overviews for a more detailed description of the new features in each of the technologies.
In addition, the following modules have been significantly improved since Qt 3:
See also Getting Started with Qt 4 for an overview of the main portability issues.
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. But we do ship a version of uic that allows you to experiment with .ui files generated by version 3 of Qt Designer. We also ship a ported version of Qt Assistant to make it easier to read the online documentation provided with this package, although the Qt 4 documentation itself is still far from complete.
The Technology Preview has been not been tested on the entire range of platforms targeted by the final Qt 4.0 release. The following platforms are supported:
Other operating systems and compilers might work but are not yet part of the testing program.
Trolltech has set up a special mailing list, qt4-preview-feedback, for discussion of Qt Technology Preview related issues. To subscribe, send a message containing just the word "subscribe" (without the quotes) to qt4-preview-feedback-request@trolltech.com. We encourage you to use this mailing list instead of qt-interest for preview-specific issues. See http://lists.trolltech.com/ for more information on Trolltech's mailing lists, including archived discussions.
We plan to enter the beta phase in Q4, 2004 and release the final Qt 4.0 in late Q1, 2005.
Enjoy the Technology Preview: We hope you will have as much fun and pleasure experimenting with Qt 4 as we had designing and building it.
