widget.newSlider() bug?

Hello, I have been trying to figure out what’s going on with my app sliders, but it’s confusing me, it might be a bug?

so I am setting default values to my three sliders to 255(R,G, B), and when I launch the app I get them like this:

What’s the cause?

#edit: it also applies on other high numbers too

Hi @waelisnothing,

Can you please post your code where you declare the 3 sliders? Remember to surround it with “lua” tags for clarity.

Thanks,

Hi @waelisnothing,

The concept of slider widgets works on percentages, not integers. So, you should convert your 0-255 values to 0-100% values.

Take care,
