SYNOPSIS

________________________________________________________________________________________________________________

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.
