To have a gettable attribute you need to make the type containing the slider an instance of Valued. See http://wxhaskell.sourceforge.net/doc/Graphics.UI.WX.Classes.html#t% 3AValued and: import qualified Graphics.UI.WX as Wx instance Wx.Valued YourTypeContainingTheSlider where value = Wx.newAttr "Value" ioActionToGetValue ioActionToSetValue there is also other classes you can make your type an instance of. See the link above. You should properly make it an instance of Widget as a minimum. I also asked about something similar before.
