CheckAll is a procedure used to set the specified values for the State, AllowGrayed, and ItemEnabled properties for all Items in the control. The default value for both aAllowGrayed and aAllowDisabled is True. CheckAll iterates over the entries in the Items property and updates the State property to match the value in the arguments to the method.
