slot in worker thread is not called

Sample program can be downloaded here which describes the problem. Desperately needing help

Problem is that signal sent from dialog is not getting called in worker thread.

I'm having a worker thread created from mainwindow and a dialog. Dialog is connected to worker thread signal and it works OK. Then I also have to send signals from dialog to workerthread but that is not working. I've read that qthread creates its own event loop in default run().

I know it has to do something with event loops but I don't know what. Please help!

Ok, so I subclassed worker thread and now it works. I guest when QThread slot 'started' is called run() is not yet being called thus EventLoop is not active
