       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.

       -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.)
