       ttk::radiobutton - Mutually exclusive option widget

SYNOPSIS

       ttk::radiobutton pathName ?options?
_________________________________________________________________________________________________

DESCRIPTION

       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.

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-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.

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.
       (The alternate state may be used to indicate a “tri-state” or “indeterminate” selection.)

STANDARD STYLES

       Ttk::radiobutton widgets support the Toolbutton style in all  standard  themes,  which  is
       useful for creating widgets for toolbars.
