Hi Brad...

I am so confused because the QLineEdit was defined by
the Qt Designer. I create the QDataBrowser from Qt
Designer and the QDataBrowser generate the QLineEdit
by themselves.

I try to define this line " QLineEditCompany =
custdataBrowser->field("custid").QString(); " in the
constructor ( init() ) but of course if I click the
button of "next"/"last"/"previos"/"first" than the
content of "company" field will not be displayed
anymore.

Please tell me your solution. Please....

Thank you very much.

void funonseqForm::init()
{
    retrieve();
}

void funonseqForm::retrieve()
{
    QSqlDatabase * bd =
QSqlDatabase::addDatabase("QPSQL7", "OTHER");
    bd->setHostName("192.168.23.237");
    bd->setDatabaseName("kv");
    bd->setUserName("postgres");
    bd->setPassword("");
    if ( ! bd->open() )
    {
	bd->lastError().showMessage();
    }
        
    QSqlCursor * cursor = new
QSqlCursor("v_cust_sven", true, bd);
    custdataBrowser->setSqlCursor(cursor, false);
    QLineEditCompany =
custdataBrowser->field("custid").QString();
    custdataBrowser->refresh();
        
}
