The iwidgets::feedback command creates a widget to display feed-

back on the current status of an ongoing 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.

The iwidgets::feedback command creates a new Tcl command whose

name is pathName. This command may be used to invoke various op- erations 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:

pathName cget option Returns the current value of the configura- tion option given by option. Option may have any of the values accepted by the scrolledhtml command. pathName configure ?op- tion? ?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_Con*- figureInfo for information on the format of this list). If op- tion 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 iwid*- gets::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.
