I am using QtableWidget to populate data collected from ROS messages:

ui->stat->setColumnCount(3); //ui->stat->setRowCount(5); countrow=0;// keep track of table rows ui->stat->setColumnWidth(0,145); ui->stat->setColumnWidth(1,50); ui->stat->setColumnWidth(2,300); QStringlist labels; labels.pushback(" Time"); labels.pushback("Type"); labels.pushback("Message "); ui->stat->setHorizontalHeaderLabels(labels); QTableWidgetItem* text = new QTableWidgetItem(); QTableWidgetItem* msgType = new QTableWidgetItem(); QTableWidgetItem* time = new QTableWidgetItem(); countrow=countrow%5; ui->stat->setItem(countrow,0,time); ui->stat->setItem(countrow,1,msgType); ui->stat->setItem(countrow,2,text); countrow++; for(int i=4;i>=0;i--) ui->stat->showRow(i);

On running the program, I am getting segmentation fault error
