QSortFilterProxyModel problem

[blukske]

Hi,

I'm wondering how to use QSortFilterProxyModel in the following situation. I have a tree mode laid out like this with 4 columns:

A 1 2 3
|_B 1 2 3

where B is a child item of A with the same number of columns as A. I have two tree views on this model. In the first tree view, I only want to see

A
|_ B

and in the second one I only want to see

1 2 3
1 2 3
