Change tableView vertical header

[tinysoft]

Hi every one..

How can i change QTreeView vertical header?

the QTreeView is presenting QSqlQueryModel .

l tried to do it this way but it did not work :

QSqlQuery qury;
 
QSqlQueryModel tableModel;
 
 qury.exec("select * from table;");
 tableModel.setQuery(qury);
 
ui->tableWidget->setModel(&tableModel);
 
for (int i=0; i<=14;i++)
    tableModel.setHeaderData(i, Qt::Vertical, stringList[i]);

QSqlQuery qury;

QSqlQueryModel tableModel;

 qury.exec("select * from table;");
 tableModel.setQuery(qury);

ui->tableWidget->setModel(&tableModel);

for (int i=0; i<=14;i++)
    tableModel.setHeaderData(i, Qt::Vertical, stringList[i]);

To copy to clipboard, switch view to plain text mode 

this code is working fine when i use it for the Horizontal header :

for (int i=0; i<=14;i++)
    tableModel.setHeaderData(i, Qt::Horizontal , stringList[i]);

for (int i=0; i<=14;i++)
    tableModel.setHeaderData(i, Qt::Horizontal , stringList[i]);

To copy to clipboard, switch view to plain text mode 

any ideas ?

thanks in advanced ..
