How to present data in a list

[ogward]

Hi!
I have this "Line edit" and a "list View" now I would like to write something in the line edit and when I press enter I would like it to be displayed in the list view.
I've writen this small line but I have no Idea what I should write for index to be displayed in the list view.

void MainWindow::on_lineEdit_2_returnPressed()
{
    on_listView_entered(line1->text());
 
}
 
 
void MainWindow::on_listView_entered(QString index)
{
 
}

void MainWindow::on_lineEdit_2_returnPressed()
{
    on_listView_entered(line1->text());

}


void MainWindow::on_listView_entered(QString index)
{
    
}

To copy to clipboard, switch view to plain text mode 

best regards
