Multithreading on its own is a complex topic; adding Qt asynchronous signals just adds a little bit of complexity to it, but when you are familiar with threads, signaling, rendevouz-patterns, barriers etc. then it should come very easy.

Unless you have a good education in multiprogramming (monitors, barriers, semaphores, reader/writer pattern...) don't touch threads! Simply don't. ;)

Try the Qt Mandelbrot example. It shows you how to implement a simple worker thread (calculation) and connecting it with the GUI, so the GUI gets updated asynchronously (and I even had to google up that word to see whether I had spelled it correctly - see, complex topics such as multithreading require complex words as well ;)

Cheers, Oliver
