可以为在wxPython中使用AppendCheckItem创建的MenuItem设置初始检查状态吗？

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        super().__init__(None, title="wxPython Example")
        
        menuBar = wx.MenuBar()
        menu = wx.Menu()
        
        menuItem = menu.AppendCheckItem(wx.ID_ANY, "Check Item")
        menuItem.Check(True)  # 设置初始检查状态为选中
        
        menuBar.Append(menu, "Menu")
        self.SetMenuBar(menuBar)
        
        self.Bind(wx.EVT_MENU, self.onMenuSelected, menuItem)
        
    def onMenuSelected(self, event):
        menuItem = event.GetEventObject()
        isChecked = menuItem.IsChecked()
        print("MenuItem is checked:", isChecked)
        

app = wx.App()
frame = MyFrame()
frame.Show()
app.MainLoop()
