Well, it's not that easy. You can't simply access some object in another process. It would have to be allocated in shared memory segment, that you can map. Better try some IPC mechanism, like DBUS.

I've never had a chance to use Squish, but I think it might use LD_PRELOAD to inject a library that intercepts calls to Qt. Other possibility is to attach to the application like a debugger. Anyway these aren't normal ways of interprocess communication.
