/* This method is called when ButtonWithValidation instances are set as toolbar
item's target. When the toolbar item needs to validate itself, it checks
whether its target adopts this validation protocol or not. If the protocol
is adopted, the validation is delegated to the target (otherwise it is
handled automatically).
With the code below, the toolbar item is validated in accordance with the
button state, in our case this is when the check box is checked. We use
ButtonWithValidation as a superclass for the check box that allows to turn
on and off this custom toolbar validation. */
