推荐答案

解决此问题的一种方法是使用AppleScript从OpenCV最前端"设置所有窗口.

One way to work around this would be to set all windows from OpenCV "frontmost" using AppleScript.

subprocess.call(["/usr/bin/osascript", "-e", 'tell app "Finder" to set frontmost of process "Python" to true'])

这样，所有窗口都应该放在最前面.

This way, all windows should be brought to the front.
