QDBusConnectionInterface¶

PyQt5.QtDBus.QDBusConnectionInterface: Inherits from QDBusAbstractInterface.

Description¶

The QDBusConnectionInterface class provides access to the D-Bus bus daemon service.

The D-Bus bus server daemon provides one special interface org.freedesktop.DBus that allows clients to access certain properties of the bus, such as the current list of clients connected. The QDBusConnectionInterface class provides access to that interface.

The most common uses of this class are to register and unregister service names on the bus using the registerService() and unregisterService() functions, query about existing names using the isServiceRegistered(), registeredServiceNames() and serviceOwner() functions, and to receive notification that a client has registered or de-registered through the serviceRegistered, serviceUnregistered and serviceOwnerChanged signals.

Flags for determining how a service registration should behave, in case the service name is already registered.

ServiceReplacementOptions.

Member	Value	Description
DontQueueService	0	If an application requests a name that is already owned, no queueing will be performed. The registeredService() call will simply fail. This is the default.
QueueService	1	Attempts to register the requested service, but do not try to replace it if another application already has it registered. Instead, simply put this application in queue, until it is given up. The serviceRegistered signal will be emitted when that happens.
ReplaceExistingService	2	If another application already has the service name registered, attempt to replace it.
