How to detect mouse over event when mouse over icon on item delegate

[umen242]

i have item delegate and im doing mouse tracking there , i can only do mouse tracking when i click with the mouse and then i check region of the mouse in the item space.
but i like to be able to catch the event when mouse is over icon, how can i do it from the model?
this is the code i have to track the mouse press:
@bool PlayListMiniItemDelegate::editorEvent(QEvent *event, QAbstractItemModel *model,
const QStyleOptionViewItem &option,
const QModelIndex &index)
{
// Emit a signal when the icon is clicked
if(!index.parent().isValid() &&
event->type() == QEvent::MouseButtonRelease) {

QMouseEvent mouseEvent = static_cast<QMouseEvent>(event);

QSize iconsize = m_iconAdd.actualSize(option.decorationSize);
QRect closeButtonRect = m_iconAdd.pixmap(iconsize.width(),iconsize.height()).
rect().translated(AddIconPos(option));

QSize iconRemoveSize = m_iconRemove.actualSize(option.decorationSize);
QRect iconRemoveRect =  m_iconRemove.pixmap(iconRemoveSize.width(),iconRemoveSize.height()).
            rect().translated(RemoveIconPos(option));


        if(closeButtonRect.contains(mouseEvent->pos()))
        {
            
 
 
emit closeButtonRectIndexClicked(index);
 
        }

else if(iconRemoveRect.contains(mouseEvent->pos()))
{

emit iconRemoveRectIndexClicked(index);

}
}
return false;
