I might be wrong but since I have not found anygroup newsgroup dedicated to PyQt5.
My small program is expected to show a window GUI for 4 seconds before changing it, so I naively coded: "... ... # codes to set up the GUI ... F0.show() # F0 being a QMainWindow object time.sleep(4) ... # codes to change the GUI set up ... F0.update() " What happens: The a blank window is displayed, freezes for 4 seconds then second set up is displayed, the original set up is not displayed. Why is not the original set up displayed? Obviously, if I remove the codes for the second set up, and the "time.sleep(4)" instruction, the original set up is displayed immediatly after I launch the execution. -- https://mail.python.org/mailman/listinfo/python-list
