_________________________________________________________________DESCRIPTION

and have an associated value; when a radiobutton is clicked, it sets
the variable to its associated value.

WIDGET-SPECIFIC 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.
WIDGET COMMAND
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 evalu‐
ates the associated -command. Returns the result of the -com‐
mand, or the empty string if no -command is specified.
WIDGET STATES
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” selec‐
tion.)
STANDARD STYLES
Ttk::radiobutton widgets support the Toolbutton style in all standard
themes, which is useful for creating widgets for toolbars.
