I've been messing with this for a year and Qt irc channel on freenode is worthless, the Qt bug people are worthless. I'm not even going to bother to describe what I've tried so far unless somebody who has actually done a custom sort filter is out there and can say that its possible. I just think the Qt item view/model is poorly designed and that its not possible.

But just in case, I thought I'd ask. I've spent at least a year of aggravation trying to get this to work so PLEASE don't flame me, don't ask me silly questions. But if you've actually subclassed the model/view framework with a custom sort, then I'd love to hear about it.
