Qt D-Bus C++ Classes
Contains miscellaneous identifiers used throughout the Qt D-Bus module
The base class of D-Bus adaptor classes
The base class for all D-Bus interfaces in the Qt D-Bus binding, allowing access to remote interfaces
Used to marshall and demarshall D-Bus arguments
Represents a connection to the D-Bus bus daemon
Access to the D-Bus bus daemon service
Allows slots to determine the D-Bus context of the calls
Represents an error received from the D-Bus bus or from remote applications found in the bus
Enables the programmer to identify the OBJECT_PATH type provided by the D-Bus typesystem
Enables the programmer to identify the SIGNATURE type provided by the D-Bus typesystem
Enables the programmer to identify the variant type provided by the D-Bus typesystem
Proxy for interfaces on remote objects
Represents one message sent or received over the D-Bus bus
Refers to one pending asynchronous call
Convenient way for waiting for asynchronous replies
Contains the reply to an asynchronous method call
Stores the reply for a method call to a remote object
Peer-to-peer communication between processes on the same computer
Allows the user to watch for a bus service change
Holds one Unix file descriptor
Used to handle several DBus paths with one class
Applications using the Qt D-Bus 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 Qt D-Bus 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:
If you're using qmake to build your application, you can add this line to your .pro file to make it link against the Qt D-Bus libraries:
QT += dbus
Note: The source code for this module is located in the
src/qdbus directory. When installing Qt from source, this module is built when Qt's tools are built.
See the D-Bus page for detailed information on how to use this module.
