Closing video window using close "X" button in OpenCV, Python

Question

I am displaying live video from a camera using OpenCV in Python. This is the code:

capture = cv.CaptureFromCAM(0)
if capture:
    cv.NamedWindow("Live Video", cv.CV_WINDOW_AUTOSIZE)
    frame = cv.QueryFrame(capture)
    if frame:
        cv.ShowImage("Live Video", frame)    
        cv.WaitKey(0)

cv.DestroyWindow("Live Video")

Now, I can only close my video window by pressing "esc", but nothing happens when I click on my window's close "X" button. Is there a way to make that work?

Answer 1

With the cv2 Python module there is a way to do that, I posted the solution here:
