Is there a python API equivalent of cvGetWindowHandle()?

Hi everyone, I've been searching for a solution to this common problem that myself and others seem to have when closing a window from a feed by clicking one the window's "X" button instead of pressing a key that gets handled by openCV.

A lot of routines involve capturing, processing, and displaying the frame inside of a while loop. Once a user presses a certain key, using cv2.waitKey allows them to enter an if statement that then closes all windows and breaks out of the routine. The problem occurs when a person clicks the "X" button on the iwindow instead of pressing whatever user-defined key to exit. I've been able to get around the program crashing when they click the X button by repeatedly showing the image in the while loop, but it would be great and more intuitive to just click the X button and be done with the routine.

Is there any equivalent python command similar to cvGetWindowHandle() or any kind of workaround to this issue? Your input is always appreciated. Thanks!

Wow... Thumbs down for asking a question that nobody apparently knows the answer to. Real mature and professional.
