ttk::radiobutton − Mutually exclusive option widget
ttk::radiobutton pathName ?options? _________________________________________________________________
ttk::radiobutton widgets are used in groups to show or change a set of mutually-exclusive options. Radiobuttons are linked to a Tcl variable, and have an associated value; when a radiobutton is clicked, it sets the variable to its associated value.

See the ttk_widget manual entry for details on the standard options.
[−command command] A Tcl script to evaluate whenever the widget is invoked. [−value Value] The value to store in the associated −variable when the widget is selected. [−variable variable] The name of a global variable whose value is linked to the widget. Default value is ::selectedButton.
In addition to
the standard cget, configure, identify,
instate, and state commands, radiobuttons
support the following additional widget commands:
pathname invoke
Sets the −variable to the −value, selects the widget, and evaluates the associated −command. Returns the result of the −command, or the empty string if no −command is specified.
The widget does not respond to user input if the disabled state is set. The widget sets the selected state whenever the linked −variable is set to the widget’s −value, and clears it otherwise. The widget sets the alternate state whenever the linked −variable is unset. (The alternate state may be used to indicate a “tri-state” or “indeterminate” selection.)
Ttk::radiobutton widgets support the Toolbutton style in all standard themes, which is useful for creating widgets for toolbars.
