hi,
I have a lineEdit and a tableView in my form. I would like to create a filter that narrows down the data existing in my database with the text entered in lineEdit; the data is shown in the tableView.
the connection to the database is working and tested
i have to following code:
QSqlQuery q1(g); // g is my database connection
q1.prepare("SELECT * FROM name where stname like ':lEstname'");
q1.bindValue(":lEstname", ui->lEstname->text());
QSqlQueryModel *filter = new QSqlQueryModel();
q1.exec();
filter->setQuery(q1);
QCompleter *completerfilter = new QCompleter (filter);
ui->lEstname->setCompleter(completerfilter);
ui->tableView->setModel(filter);
when I run, the result is the model columns headers with no data resulted from the query, just the headers, because the query is executed before I enter the text, basically with lEstname empty.
expected result would be: have all possible text entry shown in lEstname, with the QCompleter
and query results entered in tableView.
what I’m doing wrong?
thanks
