Qt is a large library consisting of several smaller libraries, or modules. The most popular ones are
core, including QObject, QThread, QFile, QVariant, and so forth
gui, all classes derived from QWidget plus some related classes
xml, for parsing and serializing XML
sql, for communicating with SQL databases
phonon, for playing multimedia files
webkit, for using an embedded web browser, QtWebkit
Except for core and gui, these modules need to be "enabled" in qmake project files. For example:
QT += xml # to use the xml module
QT -= gui # to not use QWidgets
QT += sql # to use SQL module
Section 3.2.1 will introduce some of the core library classes.
