GUI注销按钮的策略更改自动化。 pywinauto.findwindows.ElementNotFoundError:错误。如何切换上下文?

我正在自动执行更改注销按钮策略的步骤。涉及的步骤是:

  1. 使用gpedit.msc打开本地组策略
  2. 从左窗格的“用户配置”>“管理模板”下拉列表中选择“开始菜单和任务栏”
  3. 在右侧窗格中,双击“更改开始菜单电源按钮”
  4. 选择单选按钮“已启用”
  5. 从选项的下拉菜单中选择:选择“注销”

我已经完成了第三步,但是我在第二步中映射“更改开始菜单电源按钮”时遇到了问题。我的代码如下:

from pywinauto import Application

Application().start(r'mmc gpedit.msc') 
app = Application(backend="uia").connect(path='mmc.exe')
#app.LocalGroupPolicyEditor.dump_tree()

Admin_template = app.LocalGroupPolicyEditor.child_window(title="User 
Configuration", control_type="TreeItem").child_window(title="Administrative 
Templates", control_type="TreeItem") # since there are same templates 
Admin_template.double_click_input() # it expands the subtree
#Admin_template.dump_tree()

Start_menu = Admin_template.child_window(title="Start Menu and Taskbar", 
control_type="TreeItem").double_click_input()
Start_menu.dump_tree()
#Admin_template.child_window(title="Start Menu and Taskbar", 
control_type="TreeItem").dump_tree()

#Change_start_menu = Start_menu.child_window(title="Change Start Menu power 
#button", control_type="MenuItem").double_click_input()
#Change_start_menu.dump_tree()

我在查找和映射右窗格中的元素时遇到了麻烦。此外,当我使用Start_menu.dump_tree()时,只显示“通知”元素。但是,其余的,包括“更改开始菜单电源按钮”,我将在下一步双击。

我很感激帮助。谢谢。

这有点棘手,但这应该做的工作(它完成你列出的所有步骤 - 按OK - 并关闭程序):

import pywinauto

pywinauto.Application().start(r'mmc gpedit.msc') 
app = pywinauto.Application(backend="uia").connect(path='mmc.exe')

admin_template = app.LocalGroupPolicyEditor.child_window(title="User Configuration", control_type="TreeItem").child_window(title="Administrative Templates", control_type="TreeItem")
admin_template.double_click_input()

start_menu = admin_template.child_window(title="Start Menu and Taskbar", control_type="TreeItem")
start_menu.double_click_input()

option_list = app.LocalGroupPolicyEditor.child_window(auto_id="12786", control_type="List")

# Just select any of the first options to change the focus to the list.
first_elem = option_list.child_window(title="Add Search Internet link to Start Menu", control_type="ListItem")
first_elem.click_input()

# Used to scroll down the window so that the wanted option becomes visible.
pywinauto.keyboard.send_keys("cccc")

option = option_list.child_window(title="Change Start Menu power button", control_type="ListItem")
option.double_click_input()

pop_up = app.LocalGroupPolicyEditor.child_window(auto_id="tableLayoutFullForm", control_type="Pane")

radio = pop_up.child_window(title="Enabled", auto_id="radioButtonEnabled", control_type="RadioButton")
radio.click_input()

drop_down = pop_up.child_window(title="Choose one of the following actions", auto_id="dropDownListChoose one of the following actions", control_type="ComboBox")
drop_down.click_input()

# 'Hack' to first select the Restart option and then the next option after that which starts with l (=Log off).
# This ensures that the correct setting gets set despite of what the setting was before.
pywinauto.keyboard.send_keys("rl{ENTER}")

ok = pop_up.child_window(title="OK", auto_id="buttonOK", control_type="Button")
ok.click_input()

app.kill()

确保以管理员身份运行此脚本,否则将失败。

如果您对代码有任何疑问,请随时询问:)

编辑:

如果您运行的是pywinauto <0.6.0的版本,则必须将pywinauto.keyboard.send_keys()的两次出现(第19行和第34行)替换为:

pywinauto.SendKeysCtypes.SendKeys()

如果这不起作用,你可以尝试:

pywinauto.keyboard.SendKeys()
