JavaFx Slider integer only

Question

I am making a

GUI

using

JavaFx

and I need sliders that only allow

integers

to ever be selected.

I know I can use

snapToTicks

, but while pulling the

"knob"

, it can still represent a

non-integer

value. I would like to get rid of that. It messes up other components linked to it.

Basically I want something like

Swing's JSlider

, but with

JavaFx

. Is it possible? I have been searching but I can't find anything.

Answer 1

You can try to simply add a listener to the valueProperty and either set the integer value of the new Number value:

slider.valueProperty().addListener((obs, oldval, newVal) -> 
    slider.setValue(newVal.intValue()));

or alternatively you can use integer rounding using Math.round:

slider.valueProperty().addListener((obs, oldval, newVal) ->
    slider.setValue(Math.round(newVal.doubleValue())));
