wxpython菜单栏没有显示

Question

我正在尝试使用wxpython为gui编写一个时间表程序,并且正在使用wxpython wiki上的入门教程来加快wxpython的速度,但是当我尝试向wxFrame添加菜单栏时,菜单栏没有显示.任何想法为什么会这样？我使用的是ubuntu 10.10和python 2.7.代码如下:

#! /usr/bin/env python2.7
import wx, os

class MainWindow(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, title=title, size=(200,100))
        self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE)
        self.CreateStatusBar() # A Statusbar in the bottom of the window


        # Creating the menubar.
        menuBar = wx.MenuBar()

         # Setting up the menu.
        filemenu= wx.Menu()

        # wx.ID_ABOUT and wx.ID_EXIT are standard ids provided by wxWidgets.
        menuAbout = filemenu.Append(wx.ID_ABOUT, "&About"," Information about this program")
        menuExit = filemenu.Append(wx.ID_EXIT,"E&xit"," Terminate the program")

        menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
        self.SetMenuBar(menuBar)  # Adding the MenuBar to the Frame content.

        # Set events.
        self.Bind(wx.EVT_MENU, self.OnAbout, menuAbout)
        self.Bind(wx.EVT_MENU, self.OnExit, menuExit)

        self.Show(True)


    def OnAbout(self,e):

        # A message dialog box with an OK button. wx.OK is a standard ID in wxWidgets.
        dlg = wx.MessageDialog( self, "A small text editor", "About Sample Editor", wx.OK)
        dlg.ShowModal() # Show it
        dlg.Destroy() # finally destroy it when finished.

    def OnExit(self,e):
        self.Close(True)  # Close the frame.
        ''' 
        # wx.ID_ABOUT and wx.ID_EXIT are standard IDs provided by wxWidgets.
        filemenu.Append(wx.ID_ABOUT, "&About"," Information about this program")
        filemenu.AppendSeparator()
        filemenu.Append(wx.ID_EXIT,"E&xit"," Terminate the program")

        # Creating the menubar.
        menuBar = wx.MenuBar()
        menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
        self.SetMenuBar(menuBar)  # Adding the MenuBar to the Frame content.
        self.Show(True)
        '''

app = wx.App(False)
frame = MainWindow(None, "Sample editor")
app.MainLoop()

Answer 1

我有同样的错误,我使用wxWidgets提供的标准ID解决了它.

试试这个:

# wx.ID_ABOUT and wx.ID_EXIT are standard ids provided by wxWidgets.
menuAbout = filemenu.Append(102, "&About"," Information about this program")
menuExit = filemenu.Append(103,"E&xit"," Terminate the program")
