I have some comments in addition to the coding style issues mentioned by Aaron.

    This function should be named scrollTo() to match the QAbstractItemView API.
    In my opinion it also belongs in the AbstractItemView class, since it's not view specific.

    A problem with the way this function is implemented is that it assumes that the view is always sorted and that the icons always flow from left to right.
    
    When the user has rearranged the icons (m_layoutBroken is true), you have to assume that the icons are no longer arranged in a grid and that the visual order no longer matches the order in the model.
    
    When this is the case, and the user has pressed the up key for example, you have to iterate over all the icons and find the one that is closest to the current icon while still being above it.

    The implementation of this function suffers from the same problem as the one above.
    It should also use the smoothScroll() function instead of changing the scrollbar value directly.
    
    I would implement it by doing something like:
    
    const QRect r = mapFromViewport(visualRect(index));
    if (r.top() < 0) {
        smoothScroll(0, r.top());
    } else if (r.bottom() > geometry().height()) {
        smoothScroll(0, r.bottom() - geometry().height());
    }
