| \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. |
