display video camera on two different windows tkinter python - python-3.x

Question

i have a GUI python application that contain two different function windows and i'am trying to display video camera in the second window of tkinter application.
But, the video frame always be showing on the first windows!! i don't know if it is a problem of threads, or camera librairy. is there any fault in my code?
thanks in advance.
