int QDBusProxy::sendWithAsyncReply ( const QString &  method,
const QValueList< QVariant > &  params 

Sends a method call to the peer object but does not wait for an answer.

This is roughly equivalent to calling a C++ method on a local Qt event loop driven object, where the result of the method call is delivered later through a signal.

as with Qt's asychronous classes this needs a running event loop
method the name of the method to invoke
params the method parameters. Use an empty list if the method does not require parameters
a serial number to easily identify the reply once it is received or 0 if the call is not possible, i.e. the method name is empty or any of the conditions for canSend() are not met
if a asynchronous call is followed by a synchronous call, e.g. using sendWithReply(), without returning to the event loop, is recommended to call QDBusConnection::scheduleDispatch() after the synchronous call to make sure any reply received during the blocking call is delivered
