Qt's ActiveX and COM support enables Qt for Windows developers to:
- Access and use ActiveX controls and COM objects provided by any ActiveX server in their Qt applications.
- Make their Qt applications available as COM servers, with any number of Qt objects and widgets as COM objects and ActiveX controls.
For more information about using ActiveX with Qt, see Building ActiveX servers in Qt.
The ActiveQt framework consists of two modules:
- The QAxContainer module is a static library that implements a QObject subclass, QAxObject, and a QWidget subclass, QAxWidget, which act as containers for COM objects and ActiveX controls.
- The QAxServer module is a static library that implements functionality for in-process and executable COM servers. This module provides the QAxAggregated, QAxBindable, and QAxFactory classes.
A set of tools is provided to simplify the developing and building of Qt projects that use ActiveX.
find_package() command to locate the needed module components in the
find_package(Qt6 REQUIRED COMPONENTS AxContainer AxServer) target_link_libraries(mytarget PRIVATE Qt6::AxContainer Qt6::AxServer)
For more details, see the Build with CMake overview.
To configure the modules for building with qmake, add the module as a value of the
QT variable in the project's .pro file:
QT += axcontainer axserver
