Update QSqlQueryModel for show new data entered or changued in a database table from another app

Barceló

I have an object "QSqlQueryModel" to create a view that only displays a table data in sql server database 2005 but this table receives data from another app, then I need to know if there is any event or signal that allows the object "QSqlQueryModel" to update when new data is entered from the other app

@
ViFi::ViFi(QWidget *parent)
: QWidget(parent)
{

CustomSqlModel *customModelAM = new CustomSqlModel;
CustomSqlModel *customModelPM = new CustomSqlModel;
initializeModel(customModelAM, customModelPM);

QFont font12;
font12.setPointSize(14);

QHeaderView* headerViewAM = new QHeaderView(Qt::Horizontal);
QHeaderView* headerViewPM = new QHeaderView(Qt::Horizontal);
QFont* font = new QFont("Helvetica",20,10,true);
headerViewAM->setFont(*font);
headerViewAM->setResizeMode(QHeaderView::ResizeToContents);

headerViewPM->setFont(*font);
headerViewPM->setResizeMode(QHeaderView::ResizeToContents);

_tableViewAM = new QTableView;
_tableViewAM->setModel(customModelAM);      //MODEL 1
_tableViewAM->setFont(font12);
_tableViewAM->setHorizontalHeader(headerViewAM);
_tableViewAM->resizeColumnsToContents();

_tableViewPM = new QTableView;
_tableViewPM->setModel(customModelPM);      //MODEL 2
_tableViewPM->setFont(font12);
_tableViewPM->setHorizontalHeader(headerViewPM);
_tableViewPM->resizeColumnsToContents();

createWidgets();
setAttribute(Qt::WA_DeleteOnClose);

}

void ViFi::closeEvent(QCloseEvent *event)
{
event->accept();
}

void ViFi::initializeModel(QSqlQueryModel *modelAM, QSqlQueryModel *modelPM)
{

QString sqlqueryAM = QString("SELECT TOP 8 ....... ........");

QString sqlqueryPM = QString("SELECT TOP 8  ............");

qDebug() << sqlqueryAM;
//MODEL1
modelAM->setQuery(sqlqueryAM);
modelAM->setHeaderData(0, Qt::Horizontal, tr("Date"));
...
...

qDebug() << sqlqueryPM;
//MODEL2
modelPM->setQuery(sqlqueryPM);
modelPM->setHeaderData(0, Qt::Horizontal, tr("Date"));
...
...
}
@

Any suggestions?
