QDBusConnection systemBus = QDBusConnection::systemBus(); if (!systemBus.isConnected()) { qWarning() << "Failed to connect to system bus"; } else { // Do something with the system bus }
QDBusConnection sessionBus = QDBusConnection::sessionBus(); sessionBus.registerService("com.example.MyService");This code creates a QDBusConnection object for the session bus and registers a new service with the name "com.example.MyService". Other processes can now connect to and use this service via the session bus. Overall, QDBusConnection connect is a useful function for working with D-Bus in C++ applications, and is provided by the QtDBus library.
