QDBusAbstractAdaptor Class Reference

Detailed Description

The QDBusAbstractAdaptor class is the base class of D-Bus adaptor classes.

The QDBusAbstractAdaptor class is the starting point for all objects intending to provide interfaces to the external world using D-Bus. This is accomplished by attaching a one or more classes derived from QDBusAbstractAdaptor to a normal QObject and then registering that QObject with QDBusConnection::registerObject. QDBusAbstractAdaptor objects are intended to be light-weight wrappers, mostly just relaying calls into the real object (its parent) and the signals from it.

Each QDBusAbstractAdaptor-derived class should define the D-Bus interface it is implementing using the Q_CLASSINFO macro in the class definition. Note that only one interface can be exposed in this way.

QDBusAbstractAdaptor uses the standard QObject mechanism of signals, slots and properties to determine what signals, methods and properties to export to the bus. Any signal emitted by QDBusAbstractAdaptor-derived classes will be automatically be relayed through any D-Bus connections the object is registered on.

Classes derived from QDBusAbstractAdaptor must be created on the heap using the new operator and must not be deleted by the user (they will be deleted automatically when the object they are connected to is also deleted).
