Hi, I made this change yesterday, and it was described at Qt FAQ:
http://developer.qt.nokia.com/faq/answer/how_can_i_disable_autoscroll_when_selecting_a_partially_displayed_column_in

But today I found much simpler, but *undocumented* behavior:

    setAutoScroll(False)

Though the document says "This property only works if the viewport accepts
drops.", it just works. :)

http://doc.qt.nokia.com/4.6/qabstractitemview.html#autoScroll-prop

Does anyone know this is
- an expected behavior and documentation bug
- or unexpected behavior ?

Thanks,
Yuya
