Re: String class and Qt

[Gilles Degottex]

I'm not sure I understood you perfectly, but yes has I said, "slots" is a 
keyword (reserved word). and Qt classes and architecture (and related 
pre-processor program like moc and uic) depends on it.
I can't explain the whole bug and underground mechanisms, but it seems to be 
linked and I solved it with a simple rename of the variable.
