delete QListWidgetItem in QListWidget

Hi:
I have add some QListWidgetItem into a QListWidget through the following codes, and the QListWidgetItem contains both QIcon and QSrting like this:

Code:

---

ui->listWidget->addItem(new QListWidgetItem(icon, fileInfo.baseName()));
    ui->listWidget->setIconSize(QSize(40, 40));     //设置图标大小

---

But when I delete the QListWidgetItem in the QListWidget, I only know the QString of the QListWidgetItem to be deleted, and I use the following:

Code:

---

QListIterator<QListWidgetItem*> i(ui->listWidget->findItems(QString("something"), Qt::MatchCaseSensitive));
        while(i.hasNext())
        {
//            QListWidgetItem *temp = i.next();
            ui->listWidget->removeItemWidget(i.next());
//            delete temp;
        }

---

unfortunately I failed.
Do some guys know how to delete them?
Thanks!

I answer myself in case someone run into the same question.
well, I have made a mistake. I should use the condes which are commented to delete, and they work well.
