[wxhaskell-users] how to make custom controls?

[Conal E. <co...@co...>]

I want to make (or find) a float-valued slider that displays its current
value and maybe its bounds.  Does anyone have advice about doing that sort
of thing.  I want the result to have have a control-like interface,
including a gettable attribute for the current (float) value.  Thanks,  -
