pywinauto - 如何在pywinauto中连接到control.exe的子窗口

问题描述

我可以通过下面的代码打开控制面板，也可以获取所有控制面板项的 dump_tree。我的意图是在一次控制面板下面。当我尝试单击网络和共享中心时出现以下错误。有人可以帮忙吗

我的意图： - 在网络和共享中心的左侧面板中，打开更改高级共享设置 - 在网络发现下，单击“关闭网络发现”选项。-单击“保存更改”-转到工具->文件夹选项->查看。-勾选‘隐藏受保护的操作系统文件 -关闭保存

我的代码：

Application().start(r'control.exe', wait_for_idle=False)
app = Application(backend="uia").connect(title="All Control Panel Items", timeout=10)
main_window = app.window(title="All Control Panel Items")
#main_window.dump_tree()
Network=main_window.child_window(title="Network and Sharing Center", control_type="Hyperlink").select()
Network.select() # it expands the subtree

获取错误：

During handling of the above exception, another exception occurred:

pywinauto.uia_defines.NoPatternInterfaceError

标签： pywinauto

解决方案

NoPatternInterfaceError表示此操作未在应用端实现。SelectionItem 模式通常可用于 ListItem 或 TreeItem 元素。

对于超链接的使用方法.invoke()。
