Qt 5.11.3 Reference Documentation

# The Active Qt framework

Active Qt is a helper framework that enables the developer to access and use ActiveX controls and COM objects provided by any ActiveX server. It also makes it possible to make the developer's own Qt applications available as COM servers on Windows.

The two Active Qt libraries available are statically linked with the application. To avoid issues with static linking and the GNU Lesser General Public License (LGPL), it is licensed both under the commercial licenses, and the BSD 3-clause "New" or "Revised" License.
