Incorrect states in Accessibility for invisible items

Using AccExplorer 2.0 together with a test application made with Qt (see attachement, which also includes a pdf file with a detailed description of the problem)

1.) QListView
The ListView should have the items as children, not the items containing sub items
But the list view contains a list of children, where each children has a sub item with the same content, except that the parent contains an error instead of the correct parent.
2.) QTabelView / QTreeView
Rows that are not visible (because they are outside the visible area) have the state invisible, but vthey should have invisible | offscreen. This is described in MSDN in the following articles:

Same appears for the cells of a row if the corresponding column is not visible and you need a scrollbar to show it.
