-
-
- 1.Who is Trolltech?
-
- Trolltech is a software company based in Oslo, the capital of
- Norway. Our flagship product is Qt, the multi-platform C++
- GUI toolkit.
-
- Trolltech AS was founded in 1994. However, the core team of
- designers at Trolltech started developing Qt already in 1992.
- Ever since then, Qt has steadily expanded and improved. Qt is
- currently used in hundreds of software development projects
- world wide.
-
- In addition to Qt development and support, Trolltech engages
- on a consultancy basis in various exciting development projects.
-
- 2.Do you have any plans for a graphical designer/dialog
- builder?
-
- Yes, since Qt 2.2.
- See the tools/designer directory of your Qt distribution.
-
- 3.Is there a mailing list or something for Qt?
-
- There are three: qt-interest@trolltech.com, snapshot-users@trolltech.com,
- and qt-announce.
-
- Qt-interest is a user forum. There can be as much as 150
- messages per week. To join it, send a message containing the
- single word "subscribe" to qt-interest-request@trolltech.com.
-
- Snapshot-users@trolltech.com is a forum for people using the
- cutting-edge unstable version. The details of the snapshot
- releases are detailed at http://www.trolltech.com/qt-snapshots.html
-
- Qt-announce is for announcements of new Qt versions and a
- few other announcements. We expect that there will be less
- than ten messages to the list each year. To join the list, send
- mail containing the single word "subscribe" to
- qt-announce-request@trolltech.com.
-
- All messages to Qt-announce are also sent to Qt-interest, so
- you don't need to be on both lists.
-
- 4.Can I use Qt's classes without writing a graphical
- user interface?
-
- Quite a few of the classes can be used independently of the
- user interface. See utility classes, for example. There are also
- a few classes that will work without the GUI only by chance.
-
- 5.What kind of licenses exist for Qt?
-
- The Qt toolkit is available under two different licenses: The
- Professional Edition for commercial use, and the Q Public License
- for developing free software for the X platform.
-
- 6.What are the differences between the Professional
- Edition and Free Edition of Qt?
-
- You can write commercial software only if you have the
- Professional Edition. The library itself is the same. With the
- Professional Edition, you also get technical support and
- upgrades. For full details, see the LICENSE.QPL file.
-
- 7.Are you going to include so-and-so feature in Qt? If
- so, when?
-
- We try not to make public speculations about the whats and
- whens of the next Qt release too early, because we do not want
- to be known as a vaporware company.
-
- 8.I don't want to give away my source code. What do I do?
-
- Then you need the Professional Edition.
-
- 9.Can I charge for my application?
-
- If you have the Professional Edition: Yes, of course. If you use
- the Free Edition your software must be freely distributable
- and you must include the source.
-
- The Free Edition is intended for free software. We realize
- that CD-ROMs cost money to produce, for example, so you
- can charge a copying fee.
-
- 10.Where can I find Qt?
-
- The latest version of Qt 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.
-
- 11.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.
-
- 12.Will Qt be available for [OS/2, Mac, Amiga]?
-
- At present, Qt only works well on X11 and Win32 (Windows
- 95 and Windows NT). Porting to other platforms is a lower
- priority. Currently, we concentrate on the Windows and X
- versions.
-
- 13.Can I make a Qt shared library and distribute it with
- my Linux distribution?
-
- Yes, if you do not make changes to Qt and include all the files
- present in our distribution of Qt. If you absolutely need to
- change something, write to info@trolltech.com.
-
- It is very important for Trolltech that we know what is being
- distributed, so that we can guarantee the quality of Qt.
-
- 14.I found this obscure bug and I need it fixed, fast!
-
- Qt Professional Edition includes technical support. We try to
- support the developers using the Qt Free 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, our
- customers have higher priority.
