wxPython directly.

It just tried to do it another way.
There is a file for wx, and another for visio, they aren't joined 
together.
wx is filled up based on the functionnames of the other.


class ShellFrame(wx.Frame): 
    def __init__(self, parent=None, id=-1, title='PyCrustVisio'):
        ...
        self.FillUpMenu()

    def FillUpMenu(self):
        MenuItems = [item for item in dir(visio) if 
item.startswith('OnMenu')]
        for FunctionName in MenuItems:
            menuID = wx.NewId()
            menuText = FunctionName[6:]
            self.menu.Append(menuID, menuText, menuText)
            self.Bind(wx.EVT_MENU, getattr(visio, FunctionName), 
id=menuID)



So I can write it with this way:
self.Bind(wx.EVT_MENU, getattr(visio, FunctionName), id=menuID)

Every function in the visio module starting with 'OnMenu' will be appeared 
in the application menu.

Probably its a bad habit, but it is just for trial.



Yours sincerely,
