DESCRIPTION
       The iwidgets::feedback command creates a widget to display feedback on the current status of an ongo-
       ing operation to the user. Display is given as a percentage and as a thermometer  type  bar.  Options
       exist for adding a label and controlling its position.


METHODS
       The iwidgets::feedback 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 scrolledtext widgets:


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 scrolledhtml 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::feedback command.

       pathName reset
              Reset the current number of steps completed to 0, and configures the percentage complete label
              text to 0%

       pathName step ?inc?
              Increase the current number of steps completed by the amount specified by inc. Inc defaults to
              1.


EXAMPLE
               package require Iwidgets 4.0
               iwidgets::feedback .fb -labeltext "Status" -steps 20
               pack .fb -padx 10 -pady 10 -fill both -expand yes

               for {set i 0} {$i < 20} {incr i} {
                   .fb step
                   after 500
               }
