Dear All

I have a big problem like this...

I have the following code for QTableWidget

Qt Code: 
  1. treeStoklarStokBilgisi->clear();
  2.  	treeStoklarStokBilgisi->setUpdatesEnabled( false );
  3. 	QSqlDatabase cachedb = QSqlDatabase::database("cachedb");
  4.  
  5.  
  6.  
  7. QSqlQuery anas("", cachedb);
  8.  
  9. 		QString query;
  10. 		QString arananStokNo = lineStoklarParcaNo->text();
  11. 		QString arananAciklama = lineStoklarAciklama->text();
  12.  		QString arananMakina = comboStoklarMakina->currentText();
  13.  
  14. 	query = "SELECT stok.stokid, stokisim, parcano FROM stok LEFT JOIN  stokindex ON stokindex.stokid = stok.stokid WHERE stok.stokid IN (SELECT stokid FROM stokindex WHERE parcano like '" + arananStokNo + "%')";
  15. 	if (radioMakina->isChecked())
  16. 	{
  17. 		query += " AND stokid IN (SELECT makinaindex.stokid FROM makinaindex, makina WHERE makinaindex.makinaid=makina.makinaid AND makina.makina_isim ~*'" + arananMakina + "')";
  18. 	}
  19.  
  20. 	anas.exec(query);
  21.  
  22. 	while(anas.next())
  23. 	{	
  24. 		QTreeWidgetItem *i = new QTreeWidgetItem(treeStoklarStokBilgisi);
  25. 		QString aciklama;
  26. 		QString stokno;
  27.  
  28. 		//aciklama = anas.value(1).toString(); 
  29. 		//stokno = anas.value(0).toString(); 
  30. //		i->setStatusTip(0, stokno);
  31. 		i->setText(0, anas.value(2).toString());
  32. 		i->setText(1, anas.value(1).toString());
  33.  		i->setText(2, anas.value(0).toString());
  34.  
  35. 		QSqlQuery parnox;
  36. 		QSqlQuery parnox("", cachedb);
  37. 		parnox.exec("SELECT parcano FROM stokindex WHERE stokid=" + stokno + " ORDER BY sorulma DESC");
  38. 		int iR=1;
  39. 		while(parnox.next())
  40. 		{
  41. 			if(iR==1)
  42. 			{
  43. 				i->setStatusTip(0, parnox.value(0).toString());
  44. 				i->setText(0, parnox.value(0).toString());
  45. 				i->setText(1, aciklama);
  46.  				i->setText(2, stokno);
  47.  
  48. 				iR++;
  49. 			}
  50. 			else if(iR>1)
  51. 			{
  53. 				alti->setStatusTip(0, parnox.value(0).toString());
  54. 				alti->setText(0, parnox.value(0).toString());
  55. 				alti->setStatusTip(1, stokno);
  56.  				alti->setText(2, stokno);
  57. 			}
  58. 		}
  59. 	}
  60. treeStoklarStokBilgisi->setUpdatesEnabled( true );
To copy to clipboard, switch view to plain text mode 

But the problem is when I try to load the data It takes to much time for loading the tree...

Can anybody help me to solve this problem...
