Hi,

I have a QTableWidget in my app which gets updated every second. PFB the code which performs the updation:
Qt Code: 
  1. QStringList detstatsList = lStr2.split("|");//The list contains data to be loaded into the table
  2. 	int row = 0;
  3. 	ui.trafficStatsTable->setRowCount(0);//This line seems to be causing the problem :S
  4. 	for (int m = 0; m < detstatsList.size(); ++m) {
  5. 		QTableWidgetItem *resourceItem = new QTableWidgetItem(detstatsList[m]);
  6. 		if(m%4 == 0)
  7. 		{	
  8. 			row = ui.trafficStatsTable->rowCount();
  9. 			ui.trafficStatsTable->insertRow(row);
  10. 			ui.trafficStatsTable->setItem(row, 0, resourceItem);
  11. 		}
  12. 		if(m%4 == 1)
  13. 			ui.trafficStatsTable->setItem(row, 1, resourceItem);
  14. 		if(m%4 == 2)
  15. 			ui.trafficStatsTable->setItem(row, 2, resourceItem);
  16. 		if(m%4 == 3)
  17. 			ui.trafficStatsTable->setItem(row, 3, resourceItem);			
  18. 		//delete resourceItem;
  19. 	}

The program crashed out after few updates. The backtrace from gdb is given below. I am not able to figure out why removing rows is leading to a memory trouble. Could someone please help?

Backtrace(starting from the function call containing above code):
