The following extension modules are available in the Qt Commercial Editions on Windows:
QAxContainer Extension for accessing ActiveX controls
QAxServer Extension for writing ActiveX servers
The following extension module is available in all Qt Editions on Unix platforms:
QtDBus Classes for Inter-Process Communication using the D-Bus
If you use qmake to build your projects, the QtCore and QtGui modules are included by default. To link only against QtCore, add the following line to your .pro file:
QT -= gui
On Windows, if you do not use qmake, the Visual Studio Integration available to commercial licensees, or other build tools such as CMake, you also need to link against the qtmain library.
