DESCRIPTION
The iwidgets::feedback command creates a widget to display feedback 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.
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 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 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

pack .fb -padx 10 -pady 10 -fill both -expand yes
for {set i 0} {$i < 20} {incr i} {
.fb step
after 500
}
