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. + + \sa QAxBase, QAxWidget, QAxScript, {ActiveQt Framework} +*/ + +/*! + Creates an empty COM object and propagates \a parent to the + QObject constructor.
