Using it, you can get access to remote - objects, interfaces; connect remote signals to your object's slots; register objects, etc. - - D-Bus connections are created using the QDBusConnection::addConnection() function, which opens a - connection to the server daemon and does the initial handshaking, associating that connection - with a name. Further attempts to connect using the same name will return the same - connection. - - The connection is then torn down using the QDBusConnection::closeConnection() function. - - As a convenience for the two most common connection types, the QDBus::sessionBus() and - QDBus::systemBus() functions return open connections to the session server daemon and the system - server daemon, respectively. Those connections are opened when first used and are closed when - the QCoreApplication destructor is run. - - D-Bus also supports peer-to-peer connections, without the need for a bus server daemon. Using - this facility, two applications can talk to each other and exchange messages. This can be - achieved by passing an address to QDBusConnection::addConnection() - function, which was opened by another D-Bus application using QDBusServer. -*/ - -/*! - \enum QDBusConnection::BusType - Specifies the type of the bus connection.

The \c NoUseEventLoop - does not use the event loop, thus being safe from those problems, but it may block the - application for a noticeable period of time, in case the remote application fails to respond. - - Also note that calls that go back to the local application can only be placed in \c UseEventLoop - mode. -*/ - -/*! - \enum QDBusConnection::RegisterOption - Specifies the options for registering objects with the connection.
