Declaration
procedure CheckAll(AState: TCheckBoxState; AAllowGrayed: Boolean=True;

Description
CheckAll is a procedure used to set the checked state for all
check boxes defined in the
Items for the control.
AState contains the state applied to the check boxes defined in
the control.
AAllowGrayed indicates whether check boxes with an indeterminate
("grayed") state can be updated in the method.
AAllowDisabled
indicates whether check boxes which are not enabled can be updated in the
method.
CheckAll iterates over the Items defined for the control, and when
allowed using the specified arguments, sets the value in the State
property to the value in AState.
CheckAll is a convenience method; the same result can be achieved by setting
the value in the State or Checked properties for an
individual check box at a specified position.
