`pytestqt.mouseMove` 菜单栏菜单小部件移动到错误的位置
`pytestqt.mouseMove` to menubar menu widget moves to wrong place
我正在尝试将鼠标移动到菜单栏上的 File“按钮”。在我的程序中，pytestqt.mouseMove 将鼠标移动到错误的位置（它当前在 window 标题附近单击）。

问题：
鼠标移动到错误的地方：
我需要将鼠标移动到 File 按钮，以便我可以单击它。我怎样才能做到这一点？
必须考虑以下因素：
QMenu 不是“文件按钮”，而是按下该元素时显示的弹出窗口。出于这个原因，由于它不可见，屏幕的左上角被用作参考（因为它没有父级）和 QMenu 的建议大小。
“文件按钮”也不是 QWidget，而是 QMenuBar 的一部分，其中与 QMenu(menuAction() 方法)关联的 QAction 用于绘制它，因此mouseMove必须使用QMenuBar和actionGeometry()方法来获取item的坐标。
def test_menubar_click(app: MainApp, qtbot: QtBot) -> None:
# Arrange
file_menu = app.view.file_menu
menubar = app.view.menubar
qtbot.add_widget(menubar)
# Act
action_rect = menubar.actionGeometry(file_menu.menuAction())
qtbot.wait(3000)
qtbot.mouseMove(menubar, action_rect.center())
qtbot.wait(3000)
