Ok, more confusion. Here is my code and XRC. Why do I get this error 
message when I don't comment out the two lines in the InitMenu() method, 
but when they are commented it works fine (and still shows the menu bar)?

Python Error
XRC resource 'menuBar' (class 'wxMenuBar') not found!

import wx
from wx import xrc


class DBApp(wx.App):

     def OnInit(self):
         self.res = xrc.XmlResource('dbgui.xrc')
         self.InitFrame()
         self.InitMenu()
         self.frame.Show()
         return True

     def InitFrame(self):
         self.frame = self.res.LoadFrame(None, 'mainFrame')
         self.panel = xrc.XRCCTRL(self.frame, 'panel')
         self.notebook = xrc.XRCCTRL(self.panel, 'notebook')

     def InitMenu(self):
         #self.menubar = self.res.LoadMenuBar('menuBar')
         self.frame.Bind(wx.EVT_MENU, self.OnNewPage, 
id=xrc.XRCID('newRecordMenuItem'))
         #self.frame.SetMenuBar(self.menubar)

     def OnNewPage(self, evt):
         self.page = self.res.LoadPanel(self.notebook, 'dataPage')
         self.notebook.AddPage(self.page, 'Title')

     app = DBApp(False)
