无法在 pywinauto 中为我的桌面应用程序使用 print_control_identifiers()

Question

您好，我无法将“print_control_identifiers()”用于我的桌面应用程序。 我正在使用 a) Python 3.5.3（32 位，因为我正在自动化的应用程序是 32 位） b) Pywinauto 0.6.2。 我的简单代码如下：

`from pywinauto import Application
app = Application(backend="uia")    
app = Application().start(r"C:\Program Files (x86)\Trane\TRACE 3D  Plus\TRACE™ 3D Plus.exe")  
app['TRACE™ 3D Plus'].print_control_identifiers()`

当我运行上述命令时，我在命令提示符中得到以下信息：

Traceback (most recent call last):
File "D:\Python\lib\site-packages\pywinauto\application.py", line 243, in   __re
solve_control
criteria)
File "D:\Python\lib\site-packages\pywinauto\timings.py", line 424, in     wait_until_passes
raise err
pywinauto.timings.TimeoutError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "inspect.py", line 4, in <module>
app['TRACE\u2122 3D Plus'].print_control_identifiers()
File "D:\Python\lib\site-packages\pywinauto\application.py", line 573, in  prin

elements = find_elements(**kwargs)

raise MatchError(items = name_control_map.keys(), tofind = search_text)
pywinauto.findbestmatch.MatchError: Could not find 'TRACE\u2122 3D Plus' in   'dic
t_keys([])'

谁能告诉我问题是什么以及我可以做些什么来解决它？

提前致谢！

替换这些命令

app = Application(backend="uia")    
app = Application().start(r"C:\Program Files (x86)\Trane\TRACE 3D  Plus\TRACE™ 3D Plus.exe")

用这个：

app = Application(backend="uia").start(r'"C:\Program Files (x86)\Trane\TRACE 3D  Plus\TRACE™ 3D Plus.exe"')

因为如果不使用任何参数，您将使用默认 backend="win32" 重新创建 app 对象。如果很难理解，我建议先学习 Python 课程。这里需要基本的 Python 编程技能才能理解发生了什么。
