The problem is: There is no "main window update function". Painting is done via events, which are scheduled in an event queue and run via an even loop. A QTimer also uses the event loop, IIRC. There is QApplication::processEvents which can be called to run through the event loop at any given time, however that may have various side-effects which you need to be aware of. The "safest" way to do heavy work, without blocking the Ui is a separate thread. And unless you have to access main-thread-data from the worker-thread (or vice versa) this is a relative no-brainer using only events that are sent to the main thread.
