1842 \class QAxWidget
1843 \brief The QAxWidget class is a QWidget that wraps an ActiveX control.
1844
1845 \inmodule QAxContainer
1846
1847 A QAxWidget can be instantiated as an empty object, with the name
1848 of the ActiveX control it should wrap, or with an existing
1849 interface pointer to the ActiveX control. The ActiveX control's
1850 properties, methods and events which only use QAxBase
1851 supported data types, become available as Qt properties,
1852 slots and signals. The base class QAxBase provides an API to
1853 access the ActiveX directly through the \c IUnknown pointer.
1854
1855 QAxWidget is a QWidget and can mostly be used as such, e.g. it can be
1856 organized in a widget hierarchy and layouts or act as an event filter.
1857 Standard widget properties, e.g. \link QWidget::enabled
1858 enabled \endlink are supported, but it depends on the ActiveX
1859 control to implement support for ambient properties like e.g.
1860 palette or font. QAxWidget tries to provide the necessary hints.
1861
1862 However, you cannot reimplement Qt-specific event handlers like
1863 mousePressEvent or keyPressEvent and expect them to be called reliably.
1864 The embedded control covers the QAxWidget completely, and usually
1865 handles the user interface itself. Use control-specific APIs (i.e. listen
1866 to the signals of the control), or use standard COM techniques like
1867 window procedure subclassing.
1868
1869 QAxWidget also inherits most of its ActiveX-related functionality
1870 from QAxBase, notably dynamicCall() and querySubObject().
1871
1872 \warning
1873 You can subclass QAxWidget, but you cannot use the \c Q_OBJECT macro
1874 in the subclass (the generated moc-file will not compile), so you
1875 cannot add further signals, slots or properties. This limitation
1876 is due to the metaobject information generated in runtime. To work
1877 around this problem, aggregate the QAxWidget as a member of the
1878 QObject subclass.
