Our flagship product is Qt, the multi-platform C++ GUI +toolkit. + +Trolltech AS was founded in 1994, although the development of Qt +itself began in 1992. Since then, Qt has undergone continual expansion +and improvement. Qt is currently used in thousands of software +development projects world-wide. + + +---------------------------------------------------------------------------- + +Is there a graphical designer/dialog builder for Qt? + +Yes, Qt Designer. + +---------------------------------------------------------------------------- + +Are there mailing lists for Qt? + +There are three: qt-interest, qt-announce and snapshot-users. You can find +descriptions, instructions for joining them, and an archive on +http://lists.trolltech.com/ + +---------------------------------------------------------------------------- + +I think I have found a bug in Qt. Where can I report it? + +Please report to qt-bugs@trolltech.com. Remember to include the version +number of Qt, and the make and version of your compiler and your operating +system. + +---------------------------------------------------------------------------- + +Is the Reference Documentation available in printed form? + +No. But experimental PDF versions are available. + +---------------------------------------------------------------------------- + +Is the Reference Documentation available in PDF format? + +Experimentally, yes. +We recommend using the HTML format documentation which is included in +the Qt source archive and is updated with every release, minor or +major. You can browse from your local disk, you don't need to access +www.trolltech.com. Open the file qt/doc/html/index.html with your +favorite web browser, or run Qt Assistant. The PDF files are available +from ftp://ftp.trolltech.com/qt/pdf/3.0 +The PDF files are large, only updated with major version releases, and +their typesetting is experimental. We hope to improve the PDF +typesetting in future, if there is sufficient demand for this format. + +---------------------------------------------------------------------------- + +What kinds of license exist for Qt? + +The Qt toolkit is available under two different licenses: The Professional +and Enterprise Editions for commercial use on all platforms, and the Open Source +Edition for developing open source or free software for the X11 platform. + +---------------------------------------------------------------------------- + +What are the differences between the Professional/Enterprise Editions and +Open Source Edition of Qt? + +You may write commercial/proprietary/non-free software only if you +have purchased the Professional or Enterprise Edition. The library +itself is the same. With the commercial editions, you also get +technical support and upgrades. A non-commercial edition of Qt for +Microsoft Windows is available. Qt for Mac OS X is only available as +Professional and Enterprise Editions. + +---------------------------------------------------------------------------- + +Can we use the Open Source Edition while developing our non-free application +and then purchase commercial licenses when we start to sell it? + +No. The Open Source Edition license applies to the development phase +- anything developed without Professional or Enterprise Edition +licenses must be released as free/open source software. + +---------------------------------------------------------------------------- + +When will version x.y be released? Will it include so-and-so feature? + +We avoid specifying which features will be available in particular +versions or when versions will be released. This way we never make +promises that are not kept. + +---------------------------------------------------------------------------- + +Are there any books about Qt programming? + +Yes, several. They are listed on +http://www.trolltech.com/developer/documentation/literature.html + +---------------------------------------------------------------------------- + +Is there an evaluation version of Qt for Windows so I can try it out +before purchasing? + +Yes, see details on +http://www.trolltech.com/products/qt/evaluate.html + +---------------------------------------------------------------------------- + +I don't want to give away my source code. What do I do? + +Then you need a Professional or Enterprise Edition license. + +---------------------------------------------------------------------------- + +What tool do you use to create the Reference Documentation? Where can I +get it? + +The documentation generator we use is an internal tool. You might like +to investigate the Doxygen program, a free tool specifically designed +to be used for projects that make use of the Qt toolkit. Doxygen +offers functionality very similar to our internal tool, and can link +to the Qt documentation. For more information about Doxygen, visit the +Doxygen home page ( http://www.stack.nl/~dimitri/doxygen/ ). Note that +Doxygen is an independent project not supported by Trolltech. + +---------------------------------------------------------------------------- + +Can I charge for my application? + +If you have a Professional or Enterprise Edition license: Yes, of +course. If you use the Open Source Edition your software must be freely +redistributable and you must include the source. The Open Source Edition +is intended for open source software. We realize that CD-ROMs cost money +to produce, for example, so you may charge a copying fee. + + +---------------------------------------------------------------------------- + +Where can I find Qt Open Source Edition? + +The latest version of Qt Open Source Edition can be downloaded from +http://www.trolltech.com or from ftp.trolltech.com, and a whole range of +ftp mirror sites around the world. Look for a mirror near you on the list +available under http://www.trolltech.com/dl/ We encourage all developers +of free Qt software to upload their work to ftp.trolltech.com. + + +---------------------------------------------------------------------------- + +I want to port Qt to a new platform. What do I do? + +If the new platform is POSIX-like and runs the X Window System, it's +simple. Read the file PORTING for details. + +---------------------------------------------------------------------------- + +Can I make a Qt shared library and distribute it with my Linux +distribution? + +Yes. + +---------------------------------------------------------------------------- + +I found this obscure bug and I need it fixed, fast! + +Qt Professional and Enterprise Editions includes a technical support +service. We try to support the developers using the Qt Open Source Edition +as well, and we take all bug reports seriously, no matter who they come +from. But, of course, when there's too much to do, and our customers +have highest priority. + +---------------------------------------------------------------------------- + +How would you compare Qt with Java? + +We believe Qt to be a superiour solution for most development tasks, +not least for performance and portability reasons.
