You can use a QLineEdit and a QListView to get the same effect as the
QCompleter,
you need to hook up a few things, of course:
QLineEdit::textChanged signal should be connected to the
QSortFilterProxyModel::invalidate

QSortFilterProxyModel should be the model on the QListView
the show/hide events of the QListView should be deal with and you will need
a eventFilter to handle the up/down keys to send them to the QListView from
within the QLineEdit

It's doable ( I have something like this in my particular software if you
wanna take a look ) - I had to create this because QCompleter doesn't deal
with QRegExp.

(also, if it's desirable, we could add a new CompletionMode on QCompleter -
QCompleter::RegExpCompletion )
