rewrite QListView's click event

[Joyce An]

About the QListView clicked event, I want to delete the clicked event high light.
What could I do?
The QListView : public QAbstractItemView

void QAbstractItemView::mouseReleaseEvent(QMouseEvent *event)
{
    Q_D(QAbstractItemView);

    QPoint pos = event->pos();
    QPersistentModelIndex index = indexAt(pos);

    if (state() == EditingState) {
        if (d->isIndexValid(index)
            && d->isIndexEnabled(index)
            && d->sendDelegateEvent(index, event))
            update(index);
        return;
    }

    bool click = (index == d->pressedIndex && index.isValid());
    bool selectedClicked = click && (event->button() & Qt::LeftButton) && d->pressedAlreadySelected;
    EditTrigger trigger = (selectedClicked ? SelectedClicked : NoEditTriggers);
    bool edited = edit(index, trigger, event);

    d->ctrlDragSelectionFlag = QItemSelectionModel::NoUpdate;

    if (d->selectionModel && d->noSelectionOnMousePress) {
        d->noSelectionOnMousePress = false;
        d->selectionModel->select(index, selectionCommand(index, event));
    }

    setState(NoState);

    if (click) {
        emit clicked(index);
        if (edited)
            return;
        QStyleOptionViewItemV4 option = d->viewOptionsV4();
        if (d->pressedAlreadySelected)
            option.state |= QStyle::State_Selected;
        if (style()->styleHint(QStyle::SH_ItemView_ActivateItemOnSingleClick, &option, this))
            emit activated(index);
    }
}

thank you.

the QListView mouseReleaseEvent code

void QListView::mouseReleaseEvent(QMouseEvent *e)
{
    Q_D(QListView);
    QAbstractItemView::mouseReleaseEvent(e);
    // #### move this implementation into a dynamic class
    if (d->showElasticBand && d->elasticBand.isValid()) {
        d->viewport->update(d->mapToViewport(d->elasticBand));
        d->elasticBand = QRect();
    }
}

could I modify this code

 QStyleOptionViewItemV4 option = d->viewOptionsV4();
 if (d->pressedAlreadySelected)
option.state |= QStyle::State_Selected;

QStyle::State_Selected?
