how can I refresh QSqlQueryModel?

[hashb]

Hi,All

I'am using QSqlQueryModel ,but I am wondering how can I refresh the data inside it,
for example:
//

QSqlQueryModel *model = new QSqlQueryModel;
     model->setQuery("SELECT name, salary FROM employee");
     model->setHeaderData(0, Qt::Horizontal, tr("Name"));
     model->setHeaderData(1, Qt::Horizontal, tr("Salary"));
 
     QTableView *view = new QTableView;
     view->setModel(model);
     view->show();

QSqlQueryModel *model = new QSqlQueryModel;
     model->setQuery("SELECT name, salary FROM employee");
     model->setHeaderData(0, Qt::Horizontal, tr("Name"));
     model->setHeaderData(1, Qt::Horizontal, tr("Salary"));

     QTableView *view = new QTableView;
     view->setModel(model);
     view->show();

To copy to clipboard, switch view to plain text mode 

//
if I insert a row into employee using another application,
how can i refresh the QSqlQueryModel?

Thanks.
