Set model not working!!

aurora

I am using QSqlQuerModel in my program and using table view to display the contents of the model.
But when i set the model nothing displays in the table other than two brown lines at the horizontal and verticla headers.....
my program code....
@ void win::on_pushButton_clicked()
{

QStringList signalList;
QString filename;
filename="C:/Users/Desktop/abc.txt";
headersList=GetheaderNames(filename);
 
QFileInfo file&#40;filename&#41;;
createTable(file.baseName(),headersList);
GetFileContent(filename);
QSqlQueryModel plainModel2;
initializeModel(&plainModel2,file.baseName(),headersList);
 
ui->tableView_2->setModel(&plainModel2);
}@

initialiseModel function
@
void initializeModel(QSqlQueryModel *model,QString filename, QStringList headersList)
{
QString queryString=QString("select * from %1").arg(filename);

model->setQuery(queryString);
for(int i=0;i&lt;headersList.count();i++)
{
model-&gt;setHeaderData(i, Qt::Horizontal, (headersList.at(i)));
}
 
}@

Your plainModel2 is created on the stack. It is destroyed as soon as you leave the method. You will have to create it on the heap using new.
