DESCRIPTION
       The spinner command creates a spinner widget.  The spinner is comprised
       of  an  entryfield plus up and down arrow buttons.  Arrows may be drawn
       horizontally or vertically.



METHODS
       The spinner command creates a new Tcl command whose name  is  pathName.
       This  command  may  be used to invoke various operations on the widget.
       It has the following general form:

              pathName option ?arg arg ...?

       Option and the args determine the exact behavior of the  command.   The
       following commands are possible for spinner widgets:

ASSOCIATED METHODS
       delete          get            icursor         index
       insert          scan           selection       xview

       See the "entry" manual entry for details on the associated methods.

INHERITED METHODS
       childsite       clear          peek

       See  the  "entryfield" manual entry for details on the associated meth-
       ods.

WIDGET-SPECIFIC METHODS
       pathName cget option
              Returns the current value of the configuration option  given  by
              option.  Option may have any of the values accepted by the spin-
              ner command.

       pathName configure ?option? ?value option value ...?
              Query or modify the configuration options of the widget.  If  no
              option is specified, returns a list describing all of the avail-
              able options for pathName (see Tk_ConfigureInfo for  information
              on  the  format  of  this list).  If option is specified with no
              value, then the command returns a list describing the one  named
              option (this list will be identical to the corresponding sublist
              of the value returned if no option is  specified).   If  one  or
              more option-value pairs are specified, then the command modifies
              the given widget option(s) to have the given value(s);  in  this
              case  the  command returns an empty string.  Option may have any
              of the values accepted by the spinner command.

       pathName down
              Derived classes may overload this method to specialize function-
              ality.

       pathName up
              Derived classes may overload this method to specialize function-
              ality.

               set months {January February March April May June July \
                               August September October November December}

               proc blockInput {char} {
                   return 0
               }

               proc spinMonth {step} {
                   global months

                   set index [expr [lsearch $months [.sm get]] + $step]

                   if {$index < 0} {set index 11}
                   if {$index > 11} {set index 0}

                   .sm delete 0 end
                   .sm insert 0 [lindex $months $index]
               }

               spinner .sm -labeltext "Month : " -width 10 -fixed 10 -validate blockInput \
                           -decrement {spinMonth -1} -increment {spinMonth 1}
               .sm insert 0 January

               pack .sm -padx 10 -pady 10
