The connection is made from the main Qt thread. 2 Signals and Slots in PySide. The PySide Mandelbrot Example uses the traditional signals and slots syntax.

Otherwise, the behavior is the same as the Queued Connection."
Slots Signals Pyside. slots signals pyside Signals do nothing alone, but once connected to a slot, the code in the slot will be executed whenever the signal is emitted. In the Python programs, every function is a slot. It is possible to connect one signal to multiple slots, and to connect slots consecutively.
