36 Once Qt is installed, we suggest that you take a look at the demos and
37 examples to see Qt in action.
39 For desktop computers, run the Qt Examples and Demos either by
40 typing 'qtdemo' on the command line or through the desktop's Start
41 menu. On Mac OS X, you can find it in /Developers/Applications/Qt.
43 For embedded devices, launch the Qt 'fluidlauncher' demo, either through
44 the platforms filebrowser or the built in menu system.
47 REFERENCE DOCUMENTATION
49 The Qt reference documentation is available locally in Qt's doc/html
50 directory. You can use Qt Assistant to view it; to launch Assistant,
51 type 'assistant' on the command line or use the Start menu. On Mac OS
52 X, you can find it in /Developer/Applications/Qt. The latest

77 If you think you have found a bug in Qt, we would like to hear about
78 it so that we can fix it. The Qt bug tracking system is open to the
79 public at http://bugreports.qt.nokia.com/.
81 Before reporting a bug, please use the bug-tracker's search functions
82 and consult http://qt.nokia.com/developer/faqs/ to see if the issue is
85 Always include the following information in your bug report: the name
86 and version number of your compiler; the name and version number of
87 your operating system; the version of Qt you are using, and what
88 configure options it was compiled with.
90 If the problem you are reporting is only visible at run-time, try to
91 create a small test program that shows the problem when run. Often,
92 such a program can be created with some minor changes to one of the many
93 example programs in Qt's examples directory, or to the autotests that
94 are available in the public source repository on http://qt.gitorious.org/.
