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.

- Command-Line Name: -command
- Database Name: command
- Database Class: Command
- A Tcl script to evaluate whenever the widget is invoked.
- Command-Line Name: -value
- Database Name: Value
- Database Class: Value
- The value to store in the associated -variable when the
widget is selected.
- Command-Line Name: -variable
- Database Name: variable
- Database Class: 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.)
