Mouse Cursor reset problem

umen242

i have item delegate that when the mouse event is over icon i change its Cursor to Qt::PointingHandCursor
when its off i set it back to Qt::ArrowCursor . its working fine .
the problem is that besides when it over the icon . it allways stack on Qt::ArrowCursor
even in situation when the icon needs to changes nativly like when resizing the windows or when over native push button . it always Qt::ArrowCursor.
how can i force the Cursor act normally when its is no over the icon?
here is what i do :
@
bool MiniItemDelegate::editorEvent(QEvent *event, QAbstractItemModel *model,
const QStyleOptionViewItem &option,
const QModelIndex &index)
{
// Emit a signal when the icon is clicked
QMouseEvent mouseEvent = static_cast<QMouseEvent>(event);
if(!index.parent().isValid() && event->type() == QEvent::MouseMove)
{
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()))
    {                
        QApplication::setOverrideCursor(QCursor(Qt::PointingHandCursor)); 
    }
    else if(iconRemoveRect.contains(mouseEvent->pos()))
    {
        QApplication::setOverrideCursor(QCursor(Qt::PointingHandCursor)); 
    }
    else
    {
        Qt::CursorShape shape = Qt::ArrowCursor;
        QApplication::setOverrideCursor(QCursor(shape)); 
    }
}

if(!index.parent().isValid() && event->type() == QEvent::MouseButtonRelease) 
{
    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()))
    {
        ; 
    }
    else if(iconRemoveRect.contains(mouseEvent->pos()))
    {
        ; 
    }
}

return false;

}
