Qt c++ - how to show a refcursor retrieving from a postgres stored procedure?

[synpro85]

Qt postgres stored procedures
Hello, i have a trouble, i have a postgres stored function that should retrieve a ref cursor, when i call it with this instructions:

qdb.prepare("SELECT * from myfunction('cursor'); fetch all in cursor" );
qdb.exec();

qdb.prepare("SELECT * from myfunction('cursor'); fetch all in cursor" );
qdb.exec();

To copy to clipboard, switch view to plain text mode 

and i try to show it in a tableview:

QSqlQueryModel *model = new QSqlQueryModel;
 
model->setQuery(qdb1);
 
ui->tableView->setModel(model);

QSqlQueryModel *model = new QSqlQueryModel;

model->setQuery(qdb1);

ui->tableView->setModel(model);

To copy to clipboard, switch view to plain text mode 

In the tableview i only see the name of the cursor instead of the table.


So where's the problem?
when i use the same SQL query in pgadmin it returns me the table, so it goes good, but does it go wrong in Qt? Where am i wrong?
Thenks for the help!!
