The class text-input-range provides numeric input of integers in a given range (some systems refer to this a spinner or spin-box). The range is controlled by the :start and :end initargs. :start defaults to 0 and :end defaults to 10. The inital value is set with the :value initarg (which defaults to 0). The :callback initarg provides a function to be called whenever the value is changed by the user. The arguments to this function are specified by the :callback-type initarg (see the callbacks class for details of possible values, noting that the "data" is the value and the "item" is the pane itself). The default callback-type is (:item :data) .
