QTreeWidget, first visible topLevelItem?

Hi,

Assume a QTreeWidget with 1000 topLevelItem's, the user has scrolled some way down in the tree. How do i know:
1) Which topLevelItem index is the first one visible?
2) How many items are visible?

I.e. I am looking for the equivalent of Win32 ListView_GetTopIndex and ListView_GetCountPerPage.

use QTreeWidget::itemAt() with coordinates like (5,5); or something like viewport()->height()-5 for the bottom item.
