PyQt5: Threading, Signals and Slots. This example was ported from the PyQt4 version by Guðjón Guðjónsson.. Introduction. In some applications it is often necessary to perform long-running tasks, such as computations or network operations, that cannot be broken up into smaller pieces and processed alongside normal application events. The Image Pro application shows how Qt's signals and slots mechanism makes it easy to communicate with the main thread from a secondary thread.
