w->wait() doesn't block the worker thread at all. It blocks the calling thread 
(in this case, the GUI one) until the worker thread finishes executing.

I suggestion you simply don't call wait() and change the connection to 
QueuedConnection (or AutoConnection). Right now, you're calling update() from 
the worker thread, which isn't allowed.
