DESCRIPTION

This class is defined in the Qt ActiveQt Extension, which can be found in the qt/extensions directory. It is not included in the main Qt API.

The QAxBase class is an abstract class that provides an API to initalize and access a COM object.

QAxBase is an abstract class that cannot be used directly, and is instantiated through the subclasses QAxObject and QAxWidget. This class provides the API to access the COM object directly through its IUnknown implementation. If the COM object implements the IDispatch interface, the properties and methods of that object become available as Qt properties and slots.
