It is not included in the main Qt API. +<p> + +The QAxWidget class is a <a href="qwidget.html">QWidget</a> that wraps an ActiveX control. + +<p> + +<p> A QAxWidget can be instantiated as an empty object, with the name +of the ActiveX control it should wrap, or with an existing +interface pointer to the ActiveX control. The ActiveX control's +properties, methods and events which only use <a href="qaxbase.html">supported data types</a>, become available as Qt properties, +slots and signals. The base class <a href="qaxbase.html">QAxBase</a> provides an API to +access the ActiveX directly through the IUnknown pointer. +<p> QAxWidget is a QWidget and can be used as such, e.g. it can be +organized in a widget hierarchy, receive events or act as an event +filter. Standard widget properties, e.g. <a href="qwidget.html#enabled-prop">enabled</a> 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. +<p> <b>Warning:</b> +You can subclass QAxWidget, but you cannot use the <a href="metaobjects.html#Q_OBJECT">Q_OBJECT</a> macro +in the subclass (the generated <a href="moc.html#moc">moc</a>-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 +<a href="qobject.html">QObject</a> subclass. +<p> +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QAxWidget"></a>QAxWidget::QAxWidget ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 ) +</h3> +Creates an empty QAxWidget widget and propagates <em>parent</em>, <em>name</em> and <em>f</em> to the <a href="qwidget.html">QWidget</a> constructor.
