How to get TreeItem from within TreeView delegate?

[SRaD]

My TreeView delegate captures when a user hovers over a specific item in the TreeView. I'm using a custom model derived from QAbstractItemModel which holds a plain class called MyTreeItem. Within each MyTreeItem is a member varaible that holds a unique id.

Is there a way to obtain the item that the mousehover was detected over so that I can grab this id?

void MyTreeViewDelegate::paint(QPainter *painter,
const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    // ...
    if (option.state & QStyle::State_MouseOver) {

        // how to get the item that has the mouseover here?

    }
    // ...
}

Isn't index enough? From there you can get all the data with QModelIndex::data()
