I have question about using void QSqlTableModel::setFilter(const QString &filter). I have database SQL lite and I have to do a button, that searches in the database certain names. So I created the QLine Edit object (I am working in qt creator) and I don't know how to display that name that I wrote in line. Thank you for every response and sorry for my bad English and kids question, but I don't know and my deadline is coming light speed

 void MainWindow::on_pushButton_3_clicked()
{
QString edit = ui->lineEdit->text();
model->setFilter("Název = ""'+edit+'");
model->select();
}
