Re: [Audacity-devel] Generate menu; keyboard shortcut woes

[Brian G. <bm...@ya...>]

I will look at the menu code within the next week. Maybe we should remove user-defined ID's
altogether? Have Audacity generate them.

I don't know much about XML, but maybe we could use it to store the menu structure?

If that is the case, where should I store the XML? In the code or in a file?

Could you point me to a few tutorials on the language of XML itself? How to use expat to parse the
XML? (Audacity uses expat to parse its save files?)
