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.
