Qt, ListWidget update?

Question

Qt

ui->ListDevice->clear();
        int k = 1;
        for(QVector< CDevice >::iterator it = arrDevice.begin(); it != arrDevice.end(); it++){
            QListWidgetItem *itemDevice = new QListWidgetItem;
            itemDevice->setText(it->getName());
            ui->ListDevice->insertItem(k,itemDevice);
            k++;
        }

Here is the code by which I want to update the ListWidget (ListDevice), and I get an out-of-range error, if I remove the cleanup, then everything works fine, but the list simply increases and is not replaced, what is the error here?

You are trying to add a 1-position element to an empty list (indexed from 0). int k = 0; It will most likely fix the problem.
