Hi all,

I have my own model SettingsTreeModel (which is editable) and here is the part of my code:

Qt Code: 
  1. bool SettingsTreeModel::setData(const QModelIndex &index, const QVariant &value, int role)
  2. {     
  3.  
  4. StackTrace st("stm setdata");          
  5. if (role != Qt::EditRole)         
  6. 	return false;     
  7. SettingsNode *node = static_cast<SettingsNode *>(index.internalPointer());      
  8. QStringList attributeList;
  9. switch(index.column()) {         
  10. 	case 0:             
  11.     	node->setName(value.toString());             
  12.     	break; 
  13. 	case 1:             
  14.     	node->setAttributeMap(AttributeMap(value.toString()));             
  15.     	break; 
  16. 	case 2:             
  17.     	beginInsertRows(index,0,0); //a new row may be prepended.
  18.     	st.addExtraInfo(QString("beginInsertRows(%1, %2, %3)").arg(reinterpret_cast<unsigned>(index.internalPointer())).arg(0).arg(0));
  19.     	node->setValue(value.toString()); 
  20.     	endInsertRows();    //maybe?             
  21.     	break;         
  22. 	default:             
  23.     	return false;         
  24. }      
  25. emit dataChanged(index, index);      
  26. return true; 
  27. }
To copy to clipboard, switch view to plain text mode 

Here the data is changed (new row is inserted) but view doesn't show it. why do u think?

btw, i tested my model againist qt labs' modeltest and there isn't any error.
