When sing the Slider with bind data your are bound to use (no pun intended) binding.Float.
I have tried to use the slider bound to an int value and there were some unnecessary (?) work around to make it work.

Is it possible to construct a solution with the existing API?

A binding.IntToFloat can be created like below:

binding.StringToFloatWithFormat(binding.IntToStringWithFormat(myBoundInt, "%d.000000"), "%f")

boundTeaPotCount := binding.NewInt()

slider := widget.NewSliderWithData(0, 130, binding.StringToFloatWithFormat(binding.IntToStringWithFormat(boundTeaPotCount, "%d.000000"), "%f"))
label := widget.NewLabelWithData(binding.IntToString(boundTeaPotCount))

Describe the solution you'd like to see.

I am missing a (in convert.go, binding package):

func IntToFloat(v Int) Float 

and maybe

func FloatToInt(v Float) Int 

for completeness, but I am aware of the problem with design regarding rounding vs truncating of decimals.

boundTeaPotCount := binding.NewInt()

slider := widget.NewSliderWithData(0, 130, binding.IntToFloat(boundTeaPotCount))
label := widget.NewLabelWithData(binding.IntToString(boundTeaPotCount))

Sounds like a good idea, thanks.

Thanks to @Dorbmon this is now done on develop and will be in v2.5.0 in the coming month
