DESCRIPTION
       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.

       -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 command] A Tcl script to execute whenever the widget is invoked.  [-offvalue offValue] The  value  to	store  in  the	associated
       -variable when the widget is deselected.  Defaults to 0.  [-onvalue onValue] The value to store in the associated -variable when the widget
       is selected.  Defaults to 1.  [-variable variable] The name of a global variable whose value is linked to the widget.  Defaults to the wid-
       get pathname if not specified.

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

       pathname invoke
	      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.

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  -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.)

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