\class QAxObject
\brief The QAxObject class provides a QObject that wraps a COM object.
\inmodule QAxContainer
A QAxObject can be instantiated as an empty object, with the name
of the COM object it should wrap, or with a pointer to the
IUnknown that represents an existing COM object. If the COM object
implements the \c IDispatch interface, the properties, methods and
events of that object become available as Qt properties, slots and
signals. The base class, QAxBase, provides an API to access the
COM object directly through the IUnknown pointer.
QAxObject is a QObject and can be used as such, e.g. it can be
organized in an object hierarchy, receive events and connect to
signals and slots.
QAxObject also inherits most of its ActiveX-related functionality
from QAxBase, notably dynamicCall() and querySubObject().
\warning
You can subclass QAxObject, but you cannot use the Q_OBJECT macro
in the subclass (the generated moc-file will not compile), so you
cannot add further signals, slots or properties. This limitation is
due to the metaobject information generated in runtime.
To work around this problem, aggregate the QAxObject as a member of
the QObject subclass.
