Warning: The classes in this module are intended to be used in intermediate stages of a porting process and are not intended to be used in production code.
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.
