That looks good. It looks like its built on swing and sliders in swing use int, so I will be in the same spot trying to input text that represents a double and simultaneously update a slider that needs an int.
I modified that ComboSlider example so that it displays a double value, but when I try to edit the textfield it mixes the order of the numbers. That’s not useful. I mentioned a double slider example but it wont allow to edit the textfield either. I can change one digit after the decimal point but if I try to change more, it jumps to min or max.
