Re: Another userdata question

[Andrew Starks <andrew.starks@...>]

Actually, there is a missing chunk, which may already be obvious...

Your user needs to be able to set the functions.

So, when they have the userdata (or as part of its constructor), you
need to set the index metamethod to retrieve the `callbackfunctions`
table, when they ask for it:

```
mybtn.callbackfunctions.action = function() end
```

to do this, in C, just make your __index function retrieve the
uservalue from the userdata (which will automatically be at index 1 on
the stack) and return the callbackfunctions table from the uservalue
table.
