A check box control can be either selected or cleared. When you create the control, you specify the values to associate with the corresponding field when the control is selected or cleared. You can assign any two strings for the selected and cleared values of the control.
You should attach a default-value hook to the field for this control. If you do not set the initial value of the control, Rational® ClearQuest® sets its value to cleared.
