The qt-doc package provides HTML manuals and references located in /usr/share/doc/qt4/html/. This package also provides the Qt Reference Documentation, which is an excellent starting point for development within the Qt framework.

You can also install further demos and examples from qt-demos and qt-examples. To get an overview of the capabilities of the Qt framework, refer to /usr/bin/qtdemo-qt4 (provided by qt-demos).
