[wxPython-users] Can't get menu title for popup menus in Windows

[Isaac Wagner]

Sorry if I am being unclear.  I've been programming all day and my
brain is having a hard time speaking human. :)

Normally, I would do the menus as you suggest.  However, this
situation does not lend itself well to that solution.  Here's
basically the menu structure I have:

SomeText->
        Option 1
        Option 2
        Option 3
ItemA->
        Option 1
        Option 2
        Option 3
SomethingElse->
        Option 1
        Option 2
        Option 3

Information collected from runtime determines what the particular
submenu is called, in this case SomeText, ItemA, and SomethingElse.
However, the items on the submenus are always the same, in this case
Option 1, Option 2, Option 3.

Because the Submenus are generated from runtime info I have no idea
what they are ahead of time.  This is why I am doing a secondary
dispatch.  I need to determine which submenu the particular item
belongs to.

Thanks for the suggestions.
