[PyGUI] Failed when communicating between threads

[hbknjr]

I don't think signals works between two threads, they only work between main GUI and other threads.

on_GUI_changeValue function is never called as thread.start() will only execute run method.

To communicate between threads you can use global variables or queues.

"QPixmap: It is not safe to use pixmaps outside the GUI thread"

What they mean by GUI thread is the main thread that is started with .show() method.
