QMenuBar mouse tracking

[deanhystad]

In the example below, the menubar must be clicked before it begins tracking the mouse and opening menus. Does anyone know of a way that I can do this without the click? I would like hovering over a menu to open the menu without having to first click on the menubar.

from PySide6.QtWidgets import QApplication, QMainWindow, QMenuBar, QMenu

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        menu_bar = QMenuBar(self)
        self.setMenuBar(menu_bar)
        for a in "ABC":
            menu = QMenu(a, self)
            menu_bar.addMenu(menu)
            for b in "123":
                menu.addAction(a + b)


app = QApplication([])
window = MainWindow()
window.show()
app.exec_()

I can access enter and leave this way, but I haven't found a way to open the correct menu yet.
self.menu.popup always opens the last menu.

from PySide6.QtWidgets import QApplication, QMainWindow, QMenuBar, QMenu, QWidget
from PySide6.QtCore import QEvent

class MyQMenu(QMenuBar):
    def __init__(self, *args, **kwargs):
        QMenuBar.__init__(self, *args, **kwargs)
        for a in "ABC":
            self.menu = QMenu(a, self)
            self.addMenu(self.menu)
            for b in "123":
                self.menu.addAction(a + b)

    def enterEvent(self, event):
        print("enter")
        #self.menu.popup(event.globalPos())
        
    def leaveEvent(self, event):
        print("leave")

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.menu_bar = MyQMenu()
        self.setMenuBar(self.menu_bar)


app = QApplication([])
window = MainWindow()
window.show()
app.exec()
