How to make QListView consume the space when rows decrease in height on h-resize?

[wysota]

1) When I resize the QListView horizontally so its width increases, the height of the individual items should shrink (due to word-wrapping). I know my delegate reports decreasing heights via its sizeHint().

Do you emit sizeHintChanged() signal to inform about the change? Without it the view will not know it needs to read the sizeHint again.
