DESCRIPTION
ttk::radiobutton widgets are used in groups to show or change a set of mutually-exclusive options. Radiobuttons are linked to a Tcl vari-
able, 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

A Tcl script to evaluate whenever the widget is invoked.

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.
