This class is defined in the \fBQt ActiveQt Extension\fR, which can be found in the \fCqt/extensions\fR directory. It is not included in the main Qt API.
.PP
The QAxObject class provides a QObject that wraps a COM object.
.PP
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 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.
.PP
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.
\fBWarning:\fR You can subclass QAxObject, but you cannot use the TQ_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.
Calls the COM object's method \fIfunction\fR, passing the parameters \fIvar1\fR, \fIvar1\fR, \fIvar2\fR, \fIvar3\fR, \fIvar4\fR, \fIvar5\fR, \fIvar6\fR, \fIvar7\fR and \fIvar8\fR, and returns the value returned by the method, or an invalid QVariant if the method does not return a value or when the function call failed.
.PP
If \fIfunction\fR is a method of the object the string must be provided as the full prototype, for example as it would be written in a QObject::connect() call.
All parameters are passed as strings; it depends on the control whether they are interpreted correctly, and is slower than using the prototype with correctly typed parameters.
.PP
If \fIfunction\fR is a property the string has to be the name of the property. The property setter is called when \fIvar1\fR is a valid QVariant, otherwise the getter is called.

activeX->dynamicCall( "Value", 5 );

QString text = activeX->dynamicCall( "Text" ).toString();

Note that it is faster to get and set properties using QObject::property() and QObject::setProperty().
.PP
It is only possible to call functions through dynamicCall() that have parameters or return values of datatypes supported by QVariant. See the QAxBase class documentation for a list of supported and unsupported datatypes. If you want to call functions that have unsupported datatypes in the parameter list, use queryInterface() to retrieve the appropriate COM interface, and use the function directly.
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Calls the COM object's method \fIfunction\fR, passing the parameters in \fIvars\fR, and returns the value returned by the method. If the method does not return a value or when the function call failed this function returns an invalid QVariant object.
.PP
The QVariant objects in \fIvars\fR are updated when the method has out-parameters.
Returns a pointer to a QAxObject wrapping the COM object provided by the method or property \fIname\fR, passing passing the parameters \fIvar1\fR, \fIvar1\fR, \fIvar2\fR, \fIvar3\fR, \fIvar4\fR, \fIvar5\fR, \fIvar6\fR, \fIvar7\fR and \fIvar8\fR.
.PP
If \fIname\fR is provided by a method the string must include the full function prototype.
.PP
If \fIname\fR is a property the string must be the name of the property, and \fIvar1\fR, ... \fIvar8\fR are ignored.
.PP
The returned QAxObject is a child of this object (which is either of type QAxObject or QAxWidget), and is deleted when this object is deleted. It is however safe to delete the returned object yourself, and you should do so when you iterate over lists of subobjects.
.PP
COM enabled applications usually have an object model publishing certain elements of the application as dispatch interfaces. Use this method to navigate the hierarchy of the object model, e.g.
