[wxPython-users] How to know what event IDs to use in menu?

Better yet, don't use explicit IDs at all. (see the wxPython style guide 
in the Wiki)

Menu items don't behave as well as everything else in this regard, but 
you can do:

          item = menu1.Append(wx.ID_ANY, '&Open', 'Open')
# you do need to put SOMETHING in for an ID with menu items -- I use 
wx.ID_ANY, 'cause I think it says what I mean.

          self.Bind(wx.EVT_MENU, self.OnFileOpen, item)

# you can specify the object that the event comes from, rather than the
# ID, I think this is cleaner.

The tutorial is pretty old -- we've come up with cleaner ways to write 
code since then!

This is the only exception to my "no explicit IDs" rule. It IS a good 
idea to use pre-defined ids for standard items -- it lets wxMac put them 
in the right place for that platform, for instance:

              menu.Append(wx.ID_ABOUT, "&About",
                          "More information about this program")

              menu.Append(wx.ID_EXIT, "E&xit", "Terminate the program")

Don't overwrite the wx-defined ones though! See the Wiki page about 
porting to OS-X for more info.
