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”.

Syntax

%outSfield = sfield:DeepCopy

Syntax terms

%outsfield A declared ScreenField object.
%sfield A reference to an instance of a ScreenField object.

Usage notes

The method object (%screen) may be null. The output of a copy of a null object is a null object.
