Detailed Description

The QAxFactory class defines a factory for the creation of COM components.

Attention

Module: QAxServer

Implement this factory once in your COM server to provide information about the components the server can create. Subclass QAxFactory and implement the pure virtual functions in any implementation file (e.g. main.cpp), and export the factory using the QAXFACTORY_EXPORT() macro.

QStringList ActiveQtFactory::featureList() const
{
    QStringList list;
    list << "ActiveX1";
    list << "ActiveX2";
    return list;
}

QObject *ActiveQtFactory::createObject(const QString &key)
{
    if (key == "ActiveX1")
        return new ActiveX1(parent);
    if (key == "ActiveX2")
        return new ActiveX2(parent);
    return 0;
}

const QMetaObject *ActiveQtFactory::metaObject(const QString &key) const
{
    if (key == "ActiveX1")
        return &ActiveX1::staticMetaObject;
    if (key == "ActiveX2")
        return &ActiveX2::staticMetaObject;
}

QUuid ActiveQtFactory::classID(const QString &key) const
{
    if (key == "ActiveX1")
        return "{01234567-89AB-CDEF-0123-456789ABCDEF}";
    ...
    return QUuid();
}

QUuid ActiveQtFactory::interfaceID(const QString &key) const
{
    if (key == "ActiveX1")
        return "{01234567-89AB-CDEF-0123-456789ABCDEF}";
    ...
    return QUuid();
}

QUuid ActiveQtFactory::eventsID(const QString &key) const
{
    if (key == "ActiveX1")
        return "{01234567-89AB-CDEF-0123-456789ABCDEF}";
    ...
    return QUuid();
}

QAXFACTORY_EXPORT(
    ActiveQtFactory,                  // factory class
    "{01234567-89AB-CDEF-0123-456789ABCDEF}", // type library ID
    "{01234567-89AB-CDEF-0123-456789ABCDEF}"  // application ID
)

If you use the Q_CLASSINFO() macro to provide the unique identifiers or other attributes for your class you can use the QAXFACTORY_BEGIN(), QAXCLASS() and QAXFACTORY_END() macros to expose one or more classes as COM objects.

QAXFACTORY_BEGIN(
    "{01234567-89AB-CDEF-0123-456789ABCDEF}", // type library ID
    "{01234567-89AB-CDEF-0123-456789ABCDEF}"  // application ID
)
    QAXCLASS(Class1)
    QAXCLASS(Class2)
QAXFACTORY_END()

If your server supports just a single COM object, you can use a default factory implementation through the QAXFACTORY_DEFAULT() macro.

#include <qapplication.h>
#include <qaxfactory.h>

#include "theactivex.h"

QAXFACTORY_DEFAULT(
    TheActiveX,               // widget class
    "{01234567-89AB-CDEF-0123-456789ABCDEF}", // class ID
    "{01234567-89AB-CDEF-0123-456789ABCDEF}", // interface ID
    "{01234567-89AB-CDEF-0123-456789ABCDEF}", // event interface ID
    "{01234567-89AB-CDEF-0123-456789ABCDEF}", // type library ID
    "{01234567-89AB-CDEF-0123-456789ABCDEF}"  // application ID
)

Only one QAxFactory implementation may be instantiated and exported by an ActiveX server application. This instance is accessible through the global qAxFactory() function.

A factory can also reimplement the registerClass() and unregisterClass() functions to set additional flags for an ActiveX control in the registry. To limit the number of methods or properties a widget class exposes from its parent classes reimplement exposeToSuperClass().

Enumerations

ServerType

enum QAxFactory::ServerType

This enum specifies the different types of servers that can be started with startServer.

• SingleInstance The server process can create only one instance of each exported class. COM starts a new process for each request. This is typically used in servers that export only one creatable class.
• MultipleInstances The server can create multiple instances of each exported class. This is the default. All instances will live in the same thread, and will share static resources.

Functions

appID()

QUuid QAxFactory::appID ( ) const

virtual

Reimplement this function to return the ActiveX server's application identifier.

Definition at line 138 of file qaxfactory.cpp.

Referenced by DumpIDL(), and UpdateRegistry().

{
    return app;
}

classID()

QUuid QAxFactory::classID ( const QString &  key ) const

virtual

Reimplement this function to return the class identifier for each key returned by the featureList() implementation, or an empty QUuid if this factory doesn't support the value of key.

The default implementation interprets key as the class name, and returns the value of the Q_CLASSINFO() entry "ClassID".

Definition at line 191 of file qaxfactory.cpp.

Referenced by ActiveObject::ActiveObject(), classIDL(), QAxServerBase::GetClassID(), QAxServerBase::GetUserClassID(), qax_startServer(), and QClassFactory::QClassFactory().

{
    const QMetaObject *mo = metaObject(key);
    if (!mo)
        return QUuid();
    QString id = QString::fromLatin1(mo->classInfo(mo->indexOfClassInfo("ClassID")).value());

    return QUuid(id);
}

createObject()

QObject * QAxFactory::createObject ( const QString &  key )

pure virtual

Reimplement this function to return a new object for key, or 0 if this factory doesn't support the value of key.

If the object returned is a QWidget it will be exposed as an ActiveX control, otherwise the returned object will be exposed as a simple COM object.

Implemented in QAxClass< T >.

Referenced by QAxServerBase::internalCreate().

createObjectWrapper()

bool QAxFactory::createObjectWrapper ( QObject *  object, IDispatch **  wrapper  )

virtual

Reimplement this function to provide the COM object for object in wrapper.

Return true if the function was successful; otherwise return false.

The default implementation creates a generic automation wrapper based on the meta object information of object.

Referenced by ActiveObject::ActiveObject(), qax_create_object_wrapper(), and QVariantToVARIANT().

{
    *wrapper = 0;
    QAxServerBase *obj = new QAxServerBase(object);
    obj->QueryInterface(IID_IDispatch, (void**)wrapper);
    if (*wrapper)
    return true;

    delete obj;
    return false;
}

eventsID()

QUuid QAxFactory::eventsID ( const QString &  key ) const

virtual

Reimplement this function to return the identifier of the event interface for each key returned by the featureList() implementation, or an empty QUuid if this factory doesn't support the value of key.

The default implementation interprets key as the class name, and returns the value of the Q_CLASSINFO() entry "EventsID".

Definition at line 228 of file qaxfactory.cpp.

Referenced by classIDL(), QAxServerBase::GetGUID(), QAxServerBase::internalConnect(), and QAxServerBase::qt_metacall().

    return QUuid(id);
}

exposeToSuperClass()

QString QAxFactory::exposeToSuperClass ( const QString &  key ) const

virtual

Reimplement this function to return the name of the super class of key up to which methods and properties should be exposed by the ActiveX control.

The default implementation interprets key as the class name, and returns the value of the Q_CLASSINFO() entry "ToSuperClass". If no such value is set the null-string is returned, and the functions and properties of all the super classes including QWidget will be exposed.

To only expose the functions and properties of the class itself, reimplement this function to return key.

Definition at line 317 of file qaxfactory.cpp.

Referenced by classIDL().

{
    const QMetaObject *mo = metaObject(key);
    if (!mo)

}

featureList()

QStringList QAxFactory::featureList ( ) const

pure virtual

Reimplement this function to return a list of the widgets (class names) supported by this factory.

• Click
• DblClick
• KeyDown
• KeyPress
• KeyUp

Definition at line 353 of file qaxfactory.cpp.

Referenced by classIDL(), and QAxServerBase::internalCreate().

{
    const QMetaObject *mo = metaObject(key);

}

interfaceID()

QUuid QAxFactory::interfaceID ( const QString &  key ) const

virtual

Reimplement this function to return the interface identifier for each key returned by the featureList() implementation, or an empty QUuid if this factory doesn't support the value of key.

The default implementation interprets key as the class name, and returns the value of the Q_CLASSINFO() entry "InterfaceID".

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    if (!QAxFactory::isServer()) {
        // initialize for stand-alone execution
    }
    return app.exec();
}

Definition at line 371 of file qaxfactory.cpp.

{
    return qAxIsServer;
}

isService()

bool QAxFactory::isService ( ) const

virtual

Reimplement this function to return true if the server is running as a persistent service (e.g.

an NT service) and should not terminate even when all objects provided have been released.

The default implementation returns false.

Definition at line 410 of file qaxfactory.cpp.

Referenced by qax_startServer().

{
    return false;
}

metaObject()

const QMetaObject * QAxFactory::metaObject ( const QString &  key ) const

pure virtual

Reimplement this function to return the QMetaObject corresponding to key, or 0 if this factory doesn't support the value of key.

Implemented in QAxClass< T >.

Referenced by convertTypes(), QClassFactory::CreateInstanceHelper(), QClassFactory::GetLicInfo(), QAxServerBase::InternalQueryInterface(), and QClassFactory::QClassFactory().

registerActiveObject()

bool QAxFactory::registerActiveObject ( QObject *  object )

static

Registers the QObject object with COM as a running object, and returns true if the registration succeeded, otherwise returns false.

The object is unregistered automatically when it is destroyed.

This function should only be called if the application has been started by the user (i.e. not by COM to respond to a request), and only for one object, usually the toplevel object of the application's object hierarchy.

This function does nothing and returns false if the object's class info for "RegisterObject" is not set to "yes", or if the server is an in-process server.

Definition at line 512 of file qaxfactory.cpp.

{
    if (qstricmp(object->metaObject()->classInfo(object->metaObject()->indexOfClassInfo("RegisterObject")).value(), "yes"))
        return false;

    if (!QString::fromWCharArray(qAxModuleFilename).toLower().endsWith(QLatin1String(".exe")))
    return false;

    ActiveObject *active = new ActiveObject(object, qAxFactory());
    if (!active->wrapper || !active->cookie) {
        delete active;
        return false;
    }
    return true;
}

registerClass()

void QAxFactory::registerClass ( const QString &  key, QSettings *  settings  ) const

virtual

Registers additional values for the class key in the system registry using the settings object.

The standard values have already been registered by the framework, but additional values, e.g. implemented categories, can be added in an implementation of this function.

settings->setValue("/CLSID/" + classID(key)
                   + "/Implemented Categories/"
                   + "/{00000000-0000-0000-000000000000}/.",
                   QString());

If you reimplement this function you must also reimplement unregisterClass() to remove the additional registry values.

QSettings

Definition at line 252 of file qaxfactory.cpp.

{
    Q_UNUSED(key);
    Q_UNUSED(settings)
}

serverDirPath()

QString QAxFactory::serverDirPath ( )

static

Returns the directory that contains the server binary.

For out-of-process servers this is the same as QApplication::applicationDirPath(). For in-process servers that function returns the directory that contains the hosting application.

Definition at line 386 of file qaxfactory.cpp.

{
    return QFileInfo(QString::fromWCharArray(qAxModuleFilename)).absolutePath();
}

serverFilePath()

QString QAxFactory::serverFilePath ( )

static

Returns the file path of the server binary.

For out-of-process servers this is the same as QApplication::applicationFilePath(). For in-process servers that function returns the file path of the hosting application.

Definition at line 398 of file qaxfactory.cpp.

{
    return QString::fromWCharArray(qAxModuleFilename);
}

startServer()

bool QAxFactory::startServer ( ServerType  type = MultipleInstances )

inlinestatic

Starts the COM server with type and returns true if successful, otherwise returns false.

Calling this function if the server is already running (or for an in-process server) does nothing and returns true.

The server is started automatically with type set to MultipleInstances if the server executable has been started with the -activex command line parameter. To switch to SingleInstance, call

if (QAxFactory::isServer()) {
    QAxFactory::stopServer();
    QAxFactory::startServer(QAxFactory::SingleInstance);
}

in your own main() entry point function.

}

stayTopLevel()

bool QAxFactory::stayTopLevel ( const QString &  key ) const

virtual

Reimplement this function to return true if the ActiveX control key should be a top level window, e.g.

a dialog. The default implementation returns false.

Definition at line 330 of file qaxfactory.cpp.

Referenced by QAxServerBase::internalCreate().

{
    return false;
}

stopServer()

bool QAxFactory::stopServer ( )

inlinestatic

Stops the COM server and returns true if successful, otherwise returns false.

Calling this function if the server is not running (or for an in-process server) does nothing and returns true.

Stopping the server will not invalidate existing objects, but no new objects can be created from the existing server process. Usually COM will start a new server process if additional objects are requested.

The server is stopped automatically when the main() function returns.

{
    // implementation in qaxservermain.cpp

unregisterClass()

void QAxFactory::unregisterClass ( const QString &  key, QSettings *  settings  ) const

virtual

Unregisters any additional values for the class key from the system registry using the settings object.

settings->remove("/CLSID/" + classID(key)
                 + "/Implemented Categories"
                 + "/{00000000-0000-0000-000000000000}/.");

validateLicenseKey()

bool QAxFactory::validateLicenseKey ( const QString &  key, const QString &  licenseKey  ) const

virtual

Reimplement this function to return true if licenseKey is a valid license for the class key, or if the current machine is licensed.

The default implementation returns true if the class key is not licensed (ie. no Q_CLASSINFO() attribute "LicenseKey"), or if licenseKey matches the value of the "LicenseKey" attribute, or if the machine is licensed through a .LIC file with the same filename as this COM server.
