[Qt-interest] QListView: Get indexes of visible items

[Ingomar Wesp]

Hello,

In the process of porting a Java/Swing application to Qt, I stumbled over the 
following problem (I'm completely new to Qt, so please be lenient if this is 
an easy one):

I need to get the model indices for all items that are currently visible in a 
QListView (essentially the inverse of QAbstractItemView::
visualRegionForSelection). I know there's an indexAt function, but I'm not 
comfortable with using it with the top left and bottom right viewport 
coordinates because of spacing between items.

Although, because this is going to be called quite a lot, it needs to be 
reasonably fast and the QListView will have to many items,  iterating over all 
of them is definitely not the way to go.

Anyone got any hints for me?

Best regards,
Ingomar Wesp
