【问题描述】：
我是 pywinauto 的新手，刚刚开始学习。我需要找到菜单栏中存在的所有项目。 我有一个打开 7-zip 应用程序的代码，我正在尝试获取其中存在的所有菜单项。
if (os.path.exists(r"C:/Program Files/7-Zip/7zFM.exe")):
app = Application(backend='uia').start(r"C:/Program Files/7-Zip/7zFM.exe")
win = app.window()
app.top_window().descendants(control_type="MenuBar")
menu = app.top_window().descendants(control_type="MenuBar")[1]
for main_item in menu.children():
main_item.invoke()
subitems_level_1 = app.top_window().descendants(control_type="MenuItem")
print([i.window_text() for i in subitems_level_1])
# iterate expanded items (level 1)
for item in subitems_level_1:
if item.legacy_properties()[u'DefaultAction'] == u'Open':
# it has submenu
item.invoke()
subitems_level_2 = app.window(control_type="Menu", found_index=0).children()
print([i.window_text() for i in subitems_level_2])
time.sleep(3)
这是抛出错误：
