Input with Limited Setting

[RBM]

I am trying to create an integer input that is limited to 4 values only.
The input is for a period of an indicator, and the period shall be limited to 34, 21, 13, and 8 only.

This means, that I don't want to have the possibility of selecting periods other than the ones indicated above.
Is this possible ??
Thanks and cheers!

In this case, this can't be accomplished with the traditional built-in IntegerDescriptor. You might be able to make a custom IntegerDescriptor class and play around to see how it might be done.

However, since there are only 4 options you want to allow, I'd suggest just using a DiscreteDescriptor so that these 4 periods can be selected from a dropdown. Nothing wrong with this approach. Eg:

private static final List<NVP> Periods = List.of(

        new NVP("8","8"),
        new NVP("13","13"),
        new NVP("21","21"),
        new NVP("34","34")

);

inputs.addRow(new DiscreteDescriptor(Inputs.PERIOD, "Period", "8", Periods))
