This would be a focus/event/UI bug. Did you report it? If not, please do so.

One of the problems we have, and which we are fixing in master, is completion on template instantiations. For example, QStringList will complete, but when a QString is returned by a method returning the template type (like the at() method), it won't complete on that. Example:

   QStringList l;
   l.<complete> // works
   l.at(0).<complete> // doesn't work

Like I said, we're working on it, it won't be in 2.0 (or 1.x for that matter).

Regards,
Erik.
