The ActiveX control's + properties, methods and events which only use QAxBase + supported data types, become available as Qt properties, + slots and signals. The base class QAxBase provides an API to + access the ActiveX directly through the \c IUnknown pointer. + + QAxWidget is a QWidget and can mostly be used as such, e.g. it can be + organized in a widget hierarchy and layouts or act as an event filter. + Standard widget properties, e.g. \link QWidget::enabled + enabled \endlink are supported, but it depends on the ActiveX + control to implement support for ambient properties like e.g. + palette or font. QAxWidget tries to provide the necessary hints. + + However, you cannot reimplement Qt-specific event handlers like + mousePressEvent or keyPressEvent and expect them to be called reliably. + The embedded control covers the QAxWidget completely, and usually + handles the user interface itself. Use control-specific APIs (i.e. listen + to the signals of the control), or use standard COM techniques like + window procedure subclassing. + + QAxWidget also inherits most of its ActiveX-related functionality + from QAxBase, notably dynamicCall() and querySubObject(). + + \warning + You can subclass QAxWidget, but you cannot use the \c 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 QAxWidget as a member of the + QObject subclass. + + \sa QAxBase, QAxObject, QAxScript, {ActiveQt Framework} +*/ + +/*! + Creates an empty QAxWidget widget and propagates \a parent + and \a f to the QWidget constructor.
