concatanating qtablewidget items into string incorrect

[Lasith]

In my qt c++ application I have created a tablewidget with 2 coulmns and 5 rows and added items as follows!

ui->tableWidget->setRowCount(5);

ui->tableWidget->setColumnCount(2);

ui->tableWidget->setItem(0,0,new QTableWidgetItem("John"));
ui->tableWidget->setItem(0,1,new QTableWidgetItem("smith"));

ui->tableWidget->setItem(1,0,new QTableWidgetItem("Jimmy"));
ui->tableWidget->setItem(1,1,new QTableWidgetItem("michel"));

ui->tableWidget->setItem(2,0,new QTableWidgetItem("Russel"));
ui->tableWidget->setItem(2,1,new QTableWidgetItem("Arnold"));

ui->tableWidget->setItem(3,0,new QTableWidgetItem("Mary"));
ui->tableWidget->setItem(3,1,new QTableWidgetItem("Anne"));

ui->tableWidget->setItem(4,0,new QTableWidgetItem("shaun"));
ui->tableWidget->setItem(4,1,new QTableWidgetItem("Paul"));

I want to concatanate these names in to a single string and display on a label!
void MainWindow::on_pushButton_2_clicked()
{
for(int i=0;i<5;i++){
QStringList concat;
QTableWidgetItem *m=ui->tableWidget->item(i,0);
concat<< m->text();
concat<<ui->tableWidget->item(i,1)->text();
QTableWidgetItem *n=ui->tableWidget->item(i,0);
concat<< n->text();

QString concating="";
for(int i=0;i<data.size();i++){
concating+=data[i];

}

ui->label->setText(concating);
}

Instead of "JohnsmithjimmymitchelRusselArnoldMaryAnneShaunPaul" it prints "JohnsmithjohnjimmymitcheljimmyRusselArnoldRusselMaryAnneMaryShaunPaulShaun"(5 extra words) How can I correct this?

Hi,

You are concatenating twice the content of the same item. m and n are pointing to the same item. So from what you wrote you should remove the two lines handling that n object.

@SGaist Dman that was silly mistake :(
