Widget Command

pathName configure ?option? ?value option value …?
Query or modify the configuration options of the widget. 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. If option is specified with no value, then the command returns a list describing the named option: the elements of the list are the option name, database name, database class, default value, and current value. If no option is specified, returns a list describing all of the available options for pathName.
pathName cget option
Returns the current value of the configuration option given by option.
pathName identify element x y
Returns the name of the element under the point given by x and y, or an empty string if the point does not lie within any element. x and y are pixel coordinates relative to the widget. Some widgets accept other identify subcommands.
pathName instate statespec ?script?
Test the widget’s state. If script is not specified, returns 1 if the widget state matches statespec and 0 otherwise. If script is specified, equivalent to
if{[pathNameinstatestateSpec]}script
pathName state ?stateSpec?
Modify or inquire widget state. If stateSpec is present, sets the widget state: for each flag in stateSpec, sets the corresponding flag or clears it if prefixed by an exclamation point. Returns a new state spec indicating which flags were changed:
setchanges[pathNamestatespec]
pathNamestate$changes
will restore pathName to the original state. If stateSpec is not specified, returns a list of the currently-enabled state flags.

Example

set ::activated 0
proc ::EnableButtons {w} {
    foreach child [winfo children $w] {
        if {$child == "$w.cb"} continue
        if {$::activated} {
