It is not included in the main TQt API. +<p> + +The TQAxObject class provides a <a href="qobject.html">TQObject</a> that wraps a COM object. + +<p> + +<p> A TQAxObject 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 IDispatch interface, the properties, methods and +events of that object become available as TQt properties, slots and +signals. The base class, <a href="qaxbase.html">TQAxBase</a>, provides an API to access the +COM object directly through the IUnknown pointer. +<p> TQAxObject is a TQObject and can be used as such, e.g. it can be +organized in an object hierarchy, receive events and connect to +signals and slots. +<p> <b>Warning:</b> +You can subclass TQAxObject, 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 TQAxObject as a member of +the <a href="qobject.html">TQObject</a> subclass. +<p> +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQAxObject"></a>TQAxObject::TQAxObject ( <a href="qobject.html">TQObject</a> * parent = 0, const char * name = 0 ) +</h3> +Creates an empty COM object and propagates <em>parent</em> and <em>name</em> +to the <a href="qobject.html">TQObject</a> constructor.
