What it means QDoubleValidator didnt work ?

[vinaysagar]

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);

How about QDoubleSpinBox instead QLineEdit ?
