ttk::checkbutton - On/off widget

       A  ttk::checkbutton  widget  is  used  to  show  or  change  a  setting.  It has two states, selected and
       deselected.  The state of the checkbutton may be linked to a Tcl variable.

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

       In  addition  to  the  standard cget, configure, identifyelement, instate, state and style commands (see
       ttk::widget), checkbutton widgets support the following additional commands:

       pathnameinvoke
              Toggles between the selected and deselected states and evaluates the associated -command.  If  the
              widget  is  currently  selected,  sets  the  -variable  to the -offvalue and deselects the widget;
              otherwise, sets the -variable to the -onvalue Returns the result of the -command.

       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 -onvalue, 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.)
