Yes it is a very nice feature, I think I will want to do a similar thing myself
in the not too distant future though I haven't achieved this yet.

I don't understand what you mean by show up any (all the?) time. Surely the
whole point of the QToolTip::maybe method is to give you control over whether a
tooltip should/shouldn't be shown. I use QToolTip::maybeTip to allow the user to
choose whether or not they wish to show tooltips in an app. (Just return from
QToolTip::maybeTip without calling QToolTip::tip).

Getting the tooltip rectangle in the right place is another matter, I haven't
played with this but QToolTip::tip does take a rectangle as a parameter so it
might be possible. (I guess the QT tooltip example does this), you'll also need
to determine if the string in the QListView overflows the column I guess
QPainter::boundingRect is the way to go here.

One strange thing I've noticed about tooltips is that the erroneously appear
even if a child window (right terminology?) of a window covers the tipping
window, weird.

Interested to know if you get this working.

BFN,
Don.
