Detailed Description

Provides the Qtopia QDL service.

The QDL service is implemented by applications that provide link data for QDL clients. The application implementing the service should inherit from QDLService and override activateLink() and requestLinks(), to provide the indicated functionality.

See also QDLClient and QCopObjectService.

Member Function Documentation

QDLService::QDLService ( QObject * parent = 0 )

Create a new QDL service handler and attach it to parent.

QDLService::~QDLService ()

Destroy this QDL service handler.

void QDLService::activateLink ( const QByteArray & dataRef )   [pure virtual slot]

Slot that is invoked when a QLD client wishes to activate the link specified by dataRef.

This slot corresponds to the service message QDL::activateLink(QByteArray).

void QDLService::heartBeat ( const QString & id )   [signal]

Signal that is emitted when the service wants more time to respond to an requestLinks() request with a provideLinks() reply. The id should be the same as in the request.

This signal corresponds to the QCop message QDL::heartBeat(QString) on the channel QPE/QDL.

void QDLService::provideLinks ( const QString & id, const QList<QDLLink> & links )   [signal]

Signal that is emitted to respond to a requestLinks() request on the specified identifier id with the list of links.

This signal corresponds to the QCop message QDL::provideLinks(QString,QList<QDLLink>) on the channel QPE/QDL.

void QDLService::requestLinks ( const QString & id, const QString & hint )   [pure virtual slot]

Slot that is invoked when a QDL client requests the list of links supported by this service. The service should respond by emitting the provideLinks() signal with the same id.

The request hint from the client is hint. A hint is sent to a service as part of the request to help it determine pertinent data.

If the service needs an extended interval of time to respond to the message, it should emit heartBeat() periodically to notify the QDL client that the service is still alive.

This slot corresponds to the service message QDL::requestLinks(QString,QString).
