The Wrapper example demonstrates how to export existing QWidget classes as ActiveX controls, and the use of QAxFactory together with the QAXFACTORY_EXPORT() macro. ActiveX controls in this example are the standard button classes QPushButton, QCheckBox and QRadioButton as provided by Qt.
class ActiveQtFactory : public QAxFactory { public: ActiveQtFactory( const QUuid &lib, const QUuid &app ) : QAxFactory( lib, app ) {} QStringList featureList() const { QStringList list; list << "QCheckBox"; list << "QRadioButton"; list << "QPushButton"; list << "QToolButton"; return list; } QObject *createObject(const QString &key) { if ( key == "QCheckBox" ) return new QCheckBox(0); if ( key == "QRadioButton" ) return new QRadioButton(0); if ( key == "QPushButton" ) return new QPushButton(0 ); if ( key == "QToolButton" ) { QToolButton *tb = new QToolButton(0); // tb->setIcon( QPixmap(fileopen) ); return tb; } return 0; } const QMetaObject *metaObject( const QString &key ) const { if ( key == "QCheckBox" ) return &QCheckBox::staticMetaObject; if ( key == "QRadioButton" ) return &QRadioButton::staticMetaObject; if ( key == "QPushButton" ) return &QPushButton::staticMetaObject; if ( key == "QToolButton" ) return &QToolButton::staticMetaObject; return 0; } QUuid classID( const QString &key ) const { if ( key == "QCheckBox" ) return "{6E795DE9-872D-43CF-A831-496EF9D86C68}"; if ( key == "QRadioButton" ) return "{AFCF78C8-446C-409A-93B3-BA2959039189}"; if ( key == "QPushButton" ) return "{2B262458-A4B6-468B-B7D4-CF5FEE0A7092}"; if ( key == "QToolButton" ) return "{7c0ffe7a-60c3-4666-bde2-5cf2b54390a1}"; return QUuid(); } QUuid interfaceID( const QString &key ) const { if ( key == "QCheckBox" ) return "{4FD39DD7-2DE0-43C1-A8C2-27C51A052810}"; if ( key == "QRadioButton" ) return "{7CC8AE30-206C-48A3-A009-B0A088026C2F}"; if ( key == "QPushButton" ) return "{06831CC9-59B6-436A-9578-6D53E5AD03D3}"; if ( key == "QToolButton" ) return "{6726080f-d63d-4950-a366-9bf33e5cdf84}"; return QUuid(); } QUuid eventsID( const QString &key ) const { if ( key == "QCheckBox" ) return "{FDB6FFBE-56A3-4E90-8F4D-198488418B3A}"; if ( key == "QRadioButton" ) return "{73EE4860-684C-4A66-BF63-9B9EFFA0CBE5}"; if ( key == "QPushButton" ) return "{3CC3F17F-EA59-4B58-BBD3-842D467131DD}"; if ( key == "QToolButton" ) return "{f4d421fd-4ead-4fd9-8a25-440766939639}"; return QUuid(); } };
The factory implementation returns the list of supported controls, creates controls on request and provides information about the unique IDs of the COM classes and interfaces for each control.
QAXFACTORY_EXPORT( ActiveQtFactory, "{3B756301-0075-4E40-8BE8-5A81DE2426B7}", "{AB068077-4924-406a-BBAF-42D91C8727DD}" )
The factory is exported using the QAXFACTORY_EXPORT macro.
To build the example you must first build the QAxServer library. Then run qmake and your make tool in examples/activeqt/wrapper.
The demonstration requires a web browser that supports ActiveX controls, and scripting to be enabled.
