The declaration of connect is as below for QDBusConnection,

Qt Code: 
  1. bool QDBusConnection::connect ( const QString & [B]service,[/B] const QString & [B]path[/B], const QString & [B]interface[/B], const QString & [B]name[/B], const QString & signature, QObject * [B]receive[/B]r, const char * [B]slot[/B] )
To copy to clipboard, switch view to plain text mode 

now scenario is as below,

service = com.test.serivce
path = /
interface = ?
name = buttonPressed
receiver=? [because i want to call SLOT of other application whose object is not declared in this application]
slot= ? [this slot is not defined or declared in this application its a port of current application it's in other application]

If I call this connect from the process which have registered it's object service and path, Is it Possible to connect to SLOT in process which has created interface of this service(not registered any object)?

Your suggestion would be highly appriciable.
