To include the definitions of the module's classes, use the following directive:
#include <Qt3Support>
To link against the module, add this line to your qmake .pro file:
QT += qt3support
Note: Since this module provides compatibility classes for diverse parts of the Qt 3 API, it has dependencies on the QtCore, QtGui, QtNetwork, QtSql, and QtXml modules.
This module is part of the Qt Full Framework Edition and the Qt Open Source Edition. Most classes offered by this module are also part of the Qt GUI Framework Edition.
