QDbusConnection failsafe approach

[saga]

hi, i'm working on an applicaiton which use QtDbus，for some reason my application might start before DBus service，i use QtDbusConnection::systemBus() to get instance of system bus.
here is the pseudo code
dbusstarted = false;
while (!dbusstarted) {
conn = QtDbusConnection::systemBus();
dbusstarted = conn.isConntected();
sleep(n);
}
...
but i find that if dbus service is started after my app, conn.isConntected() will always return not connected result , this seems caused by systemBus() return a global static variable , my question is how to release the old conn and get a new one?
thanks in advance

Hi and welcome to devnet,

That's something you should bring to the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.
