自动化UWP相机应用

Question

我想使用python自动化Windows 10的UWP Camera应用程序。我能够启动应用程序，但之后我无法点击捕获按钮，因为我没有得到它的处理程序。

import subprocess
from pywinauto import Desktop, Application
import time sp = subprocess.call("start shell:AppsFolder\Microsoft.WindowsCamera_8wekyb3d8bbwe!App",‌​shell=True)
time.sleep(5)
app = Application().connect(title_re = ".*Camera", class_name = "ApplicationFrameWindow")

# When I do this, I get an error that app doesn't have a child window.
app.child_window(auto_id="CaptureButton_0").invoke()
