[qt-4.2] question on QAbstractItemView

[wysota]

But why create an own view? You have to use the scrollTo() method, not reimplement it.

Thanks, I managed to do scrollTo. But it came out not quite the way I wanted.
For example we have the list:
item_1
item_2
item_3
item_4
item_5
item_6
item_7
item_8
only 5 items fit into QListView list in my app, so after launch my ListView should look like this:
---------------------------
| item_7 |
| item_8 |
|--------------------------|
| item_1 |
|--------------------------|
| item_2 |
| item_3 |
---------------------------|

So the list must croll around and the central item should stay in the middle unmovable. How do I do it?
May be
void QListView::indexesMoved ( const QModelIndexList & indexes ) [signal]
void QListView::setPositionForIndex ( const QPoint & position, const QModelIndex & index ) [protected]
Or is there any other way? Please help.

Oh, you didn't mention that "detail" before

How do I do it?

Good question The easiest way is to add additional items. The proper way is probably to subclass the view and reimplement the painting and positioning routines.

Where should I add the additional items? Into the model? How do I do that?

and what routines exactly I need to reimplement in the created class, based on QListView?

Hmm... the same way you added the original items?

At least the paint event and visualRect.
