ttk::radiobutton - Mutually exclusive option widget








ttk::radiobutton pathName ?options?










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.

See the ttk_widget manual entry for details on the standard
    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.










In addition to the standard cget, configure,
    identify, instate, and state commands, radiobuttons
    support the following additional widget commands:



  

  
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.










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.)








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








The class name for a ttk::radiobutton is
    TRadiobutton.


Dynamic states: active, alternate, disabled,
    pressed, readonly, selected.


TRadiobutton styling options configurable with
    ttk::style are:


-background color
  

  -foreground color
  

  -indicatorbackground color
  

  -indicatorcolor color
  

  -indicatormargin padding
  

  -indicatorrelief relief
  

  -padding padding


Some options are only available for specific themes.


See the ttk::style manual page for information on how to
    configure ttk styles.
