How to insert rows at run time in a QTableWidget?
How to insert hard coded strings in the cells of this QTableWidget?
Here's what I tried before getting stuck... I have inserted the QTableWidget using the Qt designer.

the code:
mainwindow.h
@#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private:
Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H@
mainwindow.cpp
@
#include "mainwindow.h"
#include "ui_mainwindow.h"

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

/*add stuff inside the table view*/
QString line = "hello";
for(int i=0; i<ui->tableWidget->rowCount(); i++)
{ 
    for(int j=0; j<ui->tableWidget->columnCount(); j++)
    {
        QTableWidgetItem *pCell = ui->tableWidget->item(i, j);
        if(!pCell)
        {
            pCell = new QTableWidgetItem;
            ui->tableWidget->setItem(i, j, pCell);
        }
        if(!line.isEmpty())
            pCell->setText(line);
    }
}

#if 0
const int rowAdder = ui->tableWidget->rowCount();
ui->tableWidget->insertRow(rowAdder);
QString str = "hello";
ui->tableWidget->
#endif
}

MainWindow::~MainWindow()
{
delete ui;
}@
main.cpp
@
#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();

return a.exec();

}@

You iterate i and j up to rowCount and columnCount but you don't have any rows or columns.
Either add them in the designer or call setRowCount and setColumnCount at runtime before you start to add cells.

Thank u @Chris, i added those lines and could insert QString line in every cell.
