Bug? Spinner Behaviour

[stevel05]

Setting an increment value or initial value as a decimal allows the use of decimals in an editable spinner.

If the incr =1 and initial value = 0 a NumberFormatException error is thrown if a decimal is entered.

This is not the case if the value is changed programatically, it is truncated.

It would be useful to be able to set the initial Value to 0.00, to allow decimal values. Currently this is truncated by the IDE to 0, and no decimals can be manually entered.

Example attached.

See Spinner.SetNumericItems documentation: https://www.b4x.com/b4j/help/jfx.html#spinner_setnumericitems

It allows you to limit the spinner to integers. Set one of the four values to be non-integer and it will accept double numbers.

Thanks Erel,

I am trying to set the values using the designer where it is not possible to enter decimals that are .00.

But also doing:

Spinner1.SetNumericItems(10.00,110.00,1.00,20.00)

Causes the same issue.

The values are converted to double anyway. Set the maximum to 110.000001.

OK, that'll work. Thanks
