Namespaces

QDBusThe QDBus namespace contains miscellaneous identifiers used throughout the QtDBus library.

Classes

QDBusAbstractAdaptorThe QDBusAbstractAdaptor class is the base class of D-Bus adaptor classes.
QDBusAbstractInterfaceThe QDBusAbstractInterface class is the base class for all D-Bus interfaces in the QtDBus binding, allowing access to remote interfaces
QDBusArgumentThe QDBusArgument class is used to marshall and demarshall D-BUS arguments.
QDBusConnectionThe QDBusConnection class represents a connection to the D-Bus bus daemon.
QDBusConnectionInterfaceThe QDBusConnectionInterface class provides access to the D-Bus bus daemon service.
QDBusContextThe QDBusContext class allows slots to determine the D-Bus context of the calls.
QDBusErrorThe QDBusError class represents an error received from the D-Bus bus or from remote applications found in the bus.
QDBusInterfaceThe QDBusInterface class is a proxy for interfaces on remote objects.
QDBusMessageThe QDBusMessage class represents one message sent or received over the D-Bus bus.
QDBusObjectPathThe QDBusObjectPath class enables the programmer to identify the type provided by the D-BUS typesystem.
QDBusReplyThe QDBusReply class stores the reply for a method call to a remote object.
QDBusServerThe QDBusServer class provides peer-to-peer communication between processes on the same computer.
QDBusSignatureThe QDBusSignature class enables the programmer to identify the type provided by the D-BUS typesystem.
QDBusVariantThe QDBusVariant class enables the programmer to identify the variant type provided by the D-BUS typesystem.

Detailed Description

Applications using the QtDBus module can provide services to other, remote applications by exporting objects, as well as use services exported by those applications by placing calls and accessing properties.

The QtDBus module provides an interface that extends the Qt Signals and Slots mechanism, allowing one to connect to a signal emitted remotely as well as to connect a local signal to remote slot.

To use this module, use the following code in your application:

 #include <QtDBus>

If you're using qmake to build your application, you can add this line to your .pro file to make it link against the QtDBus libraries:

 CONFIG += qdbus

See the Introduction to D-Bus page for detailed information on how to use this module.

This module is part of all Qt editions.
