.SH DESCRIPTION
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 QAxFactory class defines a factory for the creation of COM components.
.PP

.PP
Implement this factory once in your ActiveX server to provide information about the components the server can create. If your server supports just a single ActiveX control, you can use the default factory implementation instead of implementing the factory yourself. Use the QAXFACTORY_DEFAULT macro in any implementation file (e.g. main.cpp) to instantiate and export the default factory:
.PP
.nf
.br
    #include <qapplication.h>
.br
    #include <qaxfactory.h>
.br
.br
    #include "theactivex.h"
.br
.br
    QAXFACTORY_DEFAULT(
.br
        TheActiveX,                               // widget class
.br
        "{01234567-89AB-CDEF-0123-456789ABCDEF}", // class ID
.br
        "{01234567-89AB-CDEF-0123-456789ABCDEF}", // interface ID
.br
        "{01234567-89AB-CDEF-0123-456789ABCDEF}", // event interface ID
.br
        "{01234567-89AB-CDEF-0123-456789ABCDEF}", // type library ID
.br
        "{01234567-89AB-CDEF-0123-456789ABCDEF}"  // application ID
.br
        )
.br
.fi
.PP
If you implement your own factory reimplement the pure virtual functions, provide the unique identifiers for the ActiveX controls, and use the QAXFACTORY_EXPORT macro to instantiate and export it:
.PP

    {
.br
        QStringList list;

        list << "ActiveX1";

        list << "ActiveX2";
.br
        ...
.br
        return list;
.br
    }

.br
    QWidget *ActiveQtFactory::create( const QString &key, QWidget *parent, const char *name )
.br
    {
.br
        if ( key == "ActiveX1" )
.br
            return new ActiveX1( parent, name );
.br
        if ( key == "ActiveX2" )
.br
