如何用pywinauto访问索引选项中高级按钮打开的高级选项窗口

点击索引选项中的“高级”按钮后，无法访问弹出的“高级选项”窗口，也无法获取该窗口的控件标识符，以下是我编写的代码：

from pywinauto import Application, findwindows, mouse , Desktop    
from pywinauto.timings import wait_until, TimeoutError
import time
from datetime import datetime
from time import sleep
from colorama import Fore, Back, Style, init 
import subprocess

# Opening indexing options

command = "control.exe srchadmin.dll"

subprocess.run(command, shell=True)

sleep(2)

#app = Application(backend="uia").connect(title="Indexing Options", found_index=0)
app = Application(backend='uia').connect(title='Indexing Options')

#access the child window advanced options opened thru click and open advanced options
indexing_options = app.window(title = 'Indexing Options')
#indexing_options.print_control_identifiers()
indexing_options.child_window(auto_id = '407').click()

try:
    advanced_options_window = Desktop(backend="uia")['Advanced Options']
    wait_until(10, 1, lambda: advanced_options_window.exists())

    # Print all the elements in the 'Advanced Options' window
    advanced_options_window.print_control_identifiers()

except TimeoutError:
    print("The 'Advanced Options' window did not appear.")

finally:
    # Close the Indexing Options window
    indexing_options.close()

可能的解决方向： #

• 确认窗口归属
  弹出的“高级选项”窗口大概率属于同一个应用进程，无需用Desktop跨进程查找，直接从已连接的app实例中获取。可以在点击按钮后执行print(app.windows())，查看所有关联窗口的标题，确认目标窗口是否在列表中。

• 优化等待逻辑
  替换固定sleep为pywinauto的内置等待方法，比如window.wait('visible', timeout=10)，避免因系统响应慢导致窗口未加载完成就执行后续操作。

• 尝试不同后端
  部分系统控件对uia和win32后端的支持有差异，切换到win32后端尝试连接和查找窗口：

  app = Application(backend='win32').connect(title='Indexing Options', timeout=10)
  

• 检查运行权限
  索引选项的高级设置窗口可能需要管理员权限，右键以管理员身份运行脚本，确保进程有足够权限访问该窗口。

• 调整窗口查找方式
  尝试结合标题和类名查找窗口，类名可通过Spy++工具获取：

  advanced_options_window = app.window(title='Advanced Options', class_name='#32770')
  

修改后的示例代码： #

from pywinauto import Application
from pywinauto.timings import TimeoutError
import subprocess

# 打开索引选项
command = "control.exe srchadmin.dll"
subprocess.run(command, shell=True)

# 连接到索引选项窗口，使用win32后端
app = Application(backend='win32').connect(title='Indexing Options', timeout=10)
indexing_options = app.window(title='Indexing Options')

# 点击高级按钮
indexing_options.child_window(auto_id='407').click()

try:
    # 等待高级选项窗口可见并获取
    advanced_options_window = app.window(title='Advanced Options').wait('visible', timeout=10)
    # 打印控件标识符
    advanced_options_window.print_control_identifiers()

except TimeoutError:
    print("'高级选项'窗口未出现，请检查权限或尝试切换后端")

finally:
    # 关闭索引选项窗口
    indexing_options.close()
