super()的解释

fileMenu.AppendSeparator()

这个函数是在两个子选项之间添加分隔符

MessageBox的标题是逗号后面的那句，消息内容是第一句。

wx.OK|wx.ICON_INFORMATION

红色矩形框，这一句少了会报错

不加到最后一个OnAbout也不行

每句都加也不行

只能加到最后一句

helloItem = fileMenu.Append(-1, "&Hello...\tCtrl-H",

"Help string shown in status bar for this menu item")

-1可以，-2可以，-3可以，-4不行，-4以下都不行。0---10000可以
