Hi, everyone. I'm sorry, no_keywords may be more than some people bargin for. What I mentioned is true, but there are other side effects. Specifically, Qt may redefine foreach and forever unless no_keywords is used (they provide Q_FOREACH and Q_FOREVER as alternatives).
I'm not trying to confuse the issue here (emit and signals/slots), but I didn't want anyone caught off guard by unexpected side effects. As always, I recommend reading the documentation and headers for best results (which is fairly useful in this case). D.J. On Fri, Aug 28, 2009 at 2:42 PM, D.J.
