    One way to remove item from QListWidget is to use QListWidget::takeItem which removes and returns the item :

    QList<QListWidgetItem*> items = ui->listWidget->selectedItems();
    foreach(QListWidgetItem * item, items)
    {
        delete ui->listWidget->takeItem(ui->listWidget->row(item));
    }
    

    Another way is to qDeleteAll :

    qDeleteAll(ui->listWidget->selectedItems());

    To give a solution with removeItemWidget:

    QList<QListWidgetItem*> items = ui->listWidget->selectedItems();
    
    foreach(QListWidgetItem* item, items){
        ui->listWidget->removeItemWidget(item);
        delete item; // Qt documentation warnings you to destroy item to effectively remove it from QListWidget.
    }
