NAME

       ttk::radiobutton - Mutually exclusive option widget

SYNOPSIS

       ttk::radiobutton pathName ?options?

DESCRIPTION

       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.    -class    -compound -cursor   -image
       -state    -style    -takefocus     -text -textvariable  -underline     -width

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,  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.  (The alternate state may be used to
       indicate a ``tri-state'' or ``indeterminate'' selection.)
