QDoubleValidator not working as expected on QLineEdit

[A Former User]

Hi All,

I have written the following code on QLineEdit.

QDoubleValidator *doubleVal = new QDoubleValidator( 0.0, 100.0, 2, this );
lineEdit->setValidator(doubleVal);

In above code we have set the range from 0 to 100 so when we enter digit above 100 then lineEdit should not allow to enter the value above maximum range as it is right behaviour with the QIntValidator.

As what i believe is lineedit should not allow to enter the value more then maximum value. Can you please help ?

Above code allow to enter the value 999999 which is wrong. Help me.

999999 is neither clearly wrong nor clearly ok. You still can enter 999999e-5 which leads to a valid value.

I have tried to apply below API.

doubleVal->setNotation(QDoubleValidator::StandardNotation);

Then it should not allow but it allows again 999

999 returns the Intermediate state, you still can make that number acceptable by inserting a decimal point somewhere.
