Slider · Gova

func Slider(arg any) *viewNode
 
func (n *viewNode) Range(min, max float64) *viewNode
func (n *viewNode) Step(s float64) *viewNode
func (n *viewNode) OnSliderChange(fn func(float64)) *viewNode

Slider accepts:

*StateValue[float64] for reactive binding.
float64 for a static slider.
int, converted to float64.

Any other argument panics.

The default range is 0..1. Override with .Range(min, max).

volume := gova.State(s, 50.0)
 
gova.Slider(volume).
    Range(0, 100).
    Step(5).
    OnSliderChange(func(v float64) {
        audio.SetVolume(v / 100)
    })

OnSliderChange fires continuously as the user drags. Use it for live preview; debounce in your handler if the downstream work is expensive.
