[Qt-interest] Question on QListView, QAbstractItemModel, and QSortFilterProxyModel

[christopherx]

Hello there:

    I'm a newbee  to Qt,4, and have a question if you can help.
    I have a data model built with QAbstractItemModel (subclassed from) 
in a tree fashion (ie. RootItem has childrent A, B, and A has children 
C, C1, and B has children D, D1 etc..  But I only like to display one 
level of nodes at a time, ie (A, B or C, C1) with QListView.   It seems 
not possible.
    And I tried with QSortFilterProxyModel, but no success;  Any of you 
had this issue before ?  How to you handle this  ?

Thanks,
Chris
