[Pythonmac-SIG] Menus for wxPythonMac

[Bob Ippolito]

That's quite a hairy issue.  You see, the way WindowServer and the Dock 
work, to my knowledge, is that they just *will not* register two 
separate dock instances or two menus for the same pid.

It is possible to change the menu bars dynamically, so, with appropriate 
fixes to wxWindows and/or wxPython's source code it could work by using 
submenus or something under PythonInterpreter.  But until apple (which 
they will almost certainly never do...) properly documents WindowServer 
and the behind-the-scenes stuff that goes on it's going to be pretty 
difficult to see flawless operation of any scripting language with the 
GUI.

The only solution I can think of is to make dummy application bundles 
and launch them in separate processes, and have some sort of socket 
communication between wxPython and the dummy bundles.  Each bundle would 
have to have a unique name because WindowServer seems to use argv[0] as 
it's key to redirect events back to the application, so it could get 
confused.  This is a terrible hack, but it would almost certainly work.  
The problem is that all communication to windows probably has to be done 
over sockets, unless you can get an NSApplication pointer to the dummy 
app or something, which would be awfully cool.  It'd be a lot of work 
though, obviously.
