    I have below two conditions

    • Validate the value in column of tree based on minumum and maximum range.
    • Valdiate the value in column of tree based on some fixed.

    So suppose minrange is 0 and maxrange is 24
    and fixed value is 45.

    so use can able to enter value between 0-24 and fixed value 45.

    I am able to control for minimum and maximum range using QIntValidator.

    But is there any way I can handle the same thing for fixed value using QIntValidator or any other way?

      Just to make sure I understand, a value is deemed valid if it is between 0 and 24 (inclusive) or equal to 45. Is that correct?

      If so, QIntValidator doesn’t support this. You’ll have to make your own validator. Writing a custom validator is trivial if you read the docs.

        Hi,

        Out of curiosity, why is that fixed value outside of the range ? Also why so far from the range ?
