DESCRIPTION

The feedback command creates a feedback 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 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 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 feedback command.

pathName reset
Reset status to 0%

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

EXAMPLE

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
}
