What it means QDoubleValidator didnt work ?

QDoubleValidator accepts the value out of range, it even accepts 999.

QDoubleValidator *val9 = new QDoubleValidator(0,405,1,this);
 
    ui->lineEdit->setValidator(val9);
    ui->lineEdit_2->setValidator(val9);

QDoubleValidator *val9 = new QDoubleValidator(0,405,1,this);

    ui->lineEdit->setValidator(val9);
    ui->lineEdit_2->setValidator(val9);

To copy to clipboard, switch view to plain text mode

How about QDoubleSpinBox instead QLineEdit ?
