Strange behaviour of QTableWidgetItems

Diado

Hey,

I have trouble for some time now to access the data in a QTableWidget.
To show the problem I created a new project (Qt 5.3) added a QTableWidget with some columns. Then I added following code:

@ MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

ui->tableWidget->insertRow(0);
ui->tableWidget->setItem(0,0,new QTableWidgetItem("0"));
QString test0=ui->tableWidget->itemAt(0,0)->text();

ui->tableWidget->setItem(0,1,new QTableWidgetItem("1"));
QString test1=ui->tableWidget->itemAt(0,1)->text();
ui->tableWidget->setItem(0,2,new QTableWidgetItem("2"));
QString test2=ui->tableWidget->itemAt(0,2)->text();

ui->tableWidget->setItem(0,3,new QTableWidgetItem("3"));
QString test3=ui->tableWidget->itemAt(0,3)->text();

ui->tableWidget->setItem(0,4,new QTableWidgetItem("None"));
QString test4=ui->tableWidget->itemAt(0,4)->text();

}@

Now in the table everything is displayed as expected, but all my test Strings above display "0".
Should I get with text() the same that is displayed in the table?
What am I doing wrong?

Thanks in advance for your help,

kind regards,

Diado

You want to get the item of a specific cell but you request the item of a specified pixel position! All your pixel positions refer the the first item with the string "0", so the observed behaviour is correct.

You should use the method QTableWidget::item(int row, int column) instead of itemAt(int ax, int ay).

Thanks a lot!!!!

Sometimes I can read the documentation several times, but only see what I want to see...
