DeepCopy (ScreenField function)
Return a deep copy of a screenfield object (ScreenField class)
This method returns a ScreenField object that is a deep copy of the method object. Since a ScreenField cannot exist without its underlying Screen, however, a ScreenField is deep copyable only, and no Copy method exists for a ScreenField. For more information about copyability, see “Copying Objects”.
