Hi,

You need to control in real time your QLineEdits (with textEdited() signal I presume)
checking the validity of them in the slot method and enabled the OK button accordingly:

QPushButton * okBut=ui->buttonBox->button(QDialogButtonBox::Ok);
if(valid) // all the fields are valid
  okBut->setEnabled(true);
else
  okBut->setEnabled(false);

You problably also need to set the OK button to false (disabled) when the dialog show up.

@mpergand thanks,Yes you are right I do it in a such way
connect(line, SIGNAL(textChanged(const QString &)), this, SLOT(DBsearching(const QString &)));
void Dialog::DBsearching(const QString & s)
{
for(int row = 0; row<ui->tableWidget->rowCount();row++)
{
QLineEdit l = ui->tableWidget->cellWidget(row,2)->findChild<QLineEdit>();
if(!true_city(l))
{
ui->buttonBox->setEnabled(false);
return;
}
}
ui->buttonBox->setEnabled(true);
return;
}
