No, I mean catching header clicks :)

QObject::connect(
        this->header(), SIGNAL(headerClicked(int)),
        this,           SLOT(s_headerClicked(int)));

ensureItemVisible()

AFAIK there isn't a way to do it for now. You'd have to override
QListViewItem::paintEvent(). It's not easy, but it's entirely possible. You
really don't want to do it though unless you're going to add it to the KDE
style code.

No, you can't put icons in the header columns, but I'm assured this is being
looked at by the Trolls. If you want an icon after the text, firstly you're
breaking the user's expectations, but you can do it. Again you must
override QListViewItem::paintEvent().
