ActiveQt Framework (4.6.3)

Qt's ActiveX and COM support allows Qt for Windows developers to:
1)Access and use ActiveX controls and COM objects provided by any ActiveX server in their Qt applications.
2)Make their Qt applications available as COM servers, with any number of Qt objects and widgets as COM objects and ActiveX controls

ActiveQt framework:
1)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.
2)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.
