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

alternate state whenever the linked -variable is unset. (The alternate
state may be used to indicate a “tri-state” or “indeterminate” selec‐
tion.)

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