DESCRIPTION
       The  iwidgets::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 iwidgets::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 methods.

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 iwidgets::spinner 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 available options for pathName (see Tk_ConfigureInfo  for  informa-tion information
              tion  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 correspond-ing corresponding
              ing  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 val-ues values
              ues accepted by the iwidgets::spinner command.

       pathName down
              Derived classes may overload this method to specialize functionality.

       pathName up
              Derived classes may overload this method to specialize functionality.


COMPONENTS
       Name:           downarrow

              The downarrow component is the downward pointing button of the spinner.  See the "canvas" wid-get widget
              get manual entry for details on the downarrow component item.

       Name:           uparrow
       Class:          Canvas

EXAMPLE
               package require Iwidgets 4.0
               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]
               }

               iwidgets::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
