The clearSelection does not work in my case. I'm using treeviews with a singleselection mode. Here is what I've coded:

class DeselectableTreeView : public QTreeView
{
public:
    DeselectableTreeView(QWidget *parent) : QTreeView(parent) {}
    virtual ~DeselectableTreeView() {}

private:
    virtual void mousePressEvent(QMouseEvent *event)
    {
        QModelIndex item = indexAt(event->pos());
        bool selected = selectionModel()->isSelected(item);
        QTreeView::mousePressEvent(event);
        if (selected)
            selectionModel()->select(item, QItemSelectionModel::Deselect);
    }

};

This works really fine.
