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. STANDARD OPTIONS -class -compound -cursor -image -state -style -takefocus -text -textvariable -underline -width See the ttk_widget manual entry for details on the standard options. 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 evaluates the associated -command. Returns the result of the -command, 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.
