Pywinauto无法点击QT桌面应用上下文菜单问题求助

我在用Pywinauto操作公司自研的QT界面视频会议应用（TrueConf）时，遇到了上下文菜单项点击无效的问题：鼠标光标能移到目标元素，但点击没反应，菜单项也不会像手动悬停那样变色。手动操作时菜单完全正常。

尝试过的操作 #

• 按名称、序号定位元素后调用click_input()
• 用Pywinauto的mouse模块按坐标点击
• 对目标菜单项的父控件调用set_focus()

我的代码 #

app_dlg['Button4'].click_input() # 激活打开上下文菜单的按钮
app_dlg['MenuItem2'].click_input() # 点击菜单项

print_control_identifiers()输出 #

截图说明 #

• Pywinauto识别的菜单结构：标记了目标菜单项"Spotlighted video"
• 手动操作菜单：同位置菜单项可正常交互、悬停变色

解决方案尝试 #

1. 精准嵌套定位控件

从控件树看，菜单项位于嵌套的子Dialog中，直接通过顶级Dialog定位可能失效，需逐层定位：

# 定位菜单所在的子Dialog
menu_dlg = app_dlg.child_window(title="TrueConf", control_type="Window")
# 定位菜单控件
menu = menu_dlg.child_window(control_type="Menu")
# 定位目标菜单项
target_item = menu.child_window(title="Spotlighted video", control_type="MenuItem")

# 聚焦菜单后点击
menu.set_focus()
target_item.click_input()

2. 尝试双击操作

部分QT应用对单点击响应异常，改用双击：

target_item.double_click_input()

3. 键盘模拟选择

打开菜单后用方向键+回车模拟手动操作：

import time
from pywinauto import keyboard

app_dlg['Button4'].click_input()
# 等待菜单加载
time.sleep(0.5)
# 向下移动到目标项（第二个菜单项，按一次向下键）
keyboard.send_keys('{DOWN}')
# 确认选择
keyboard.send_keys('{ENTER}')

4. 切换到UIA后端

QT应用通常对UIA后端支持更好，初始化时指定：

from pywinauto import Application
app = Application(backend='uia').connect(title_re="TrueConf — Conference")
app_dlg = app.window(title_re="TrueConf — Conference")

5. 检查控件状态

点击前确认控件可见且启用：

print(target_item.is_visible())
print(target_item.is_enabled())

# 等待控件加载完成
from pywinauto.timings import wait_until
wait_until(2, 0.5, target_item.is_visible)
