## toggling-widget

The non-instantiable `dialog-item` class that groups together all widgets that have a value that can be toggled between true and `nil`. (An exception is the `static-picture` subclass, which does not have a true-or-nil value but which is grouped with the `picture-button` class for other reasons.)

The subclasses are `button`, `check-box`, `radio-button`, and `picture-widget`.

A diagram of window and widget classes is shown in Widget and window classes in cgide.htm.
