Active Qt▲
Qt's ActiveX and COM support allows 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 implementing QObject and QWidget subclasses, QAxObject and QAxWidget, that 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.
To build the static libraries, change into the activeqt directory (usually QTDIR/src/activeqt), and run qmake and your make tool in both the container and the control subdirectory. The qaxcontainer and qaxserver libraries will be linked into QTDIR/lib.
If you are using a shared configuration of Qt enter the plugin subdirectory and run qmake and your make tool to build a plugin that integrates the QAxContainer module into Qt Designer.
