Moving and Resizing a Global Object 14–6
A global object is a single object that can be referenced on multiple
screens in an application. A global object is created and stored once
regardless of the number of times it is used.
For example, if you want to use the same control or display object on
different screens, define the object as a global object. You can
reference a global object from any screen (without recreating it).
The benefits of using a global object are:
•
reduced development time
Reference a global object on multiple screens without having to
recreate the object. When properties of a global object are edited,
all instances of that object are automatically updated.
•
reduced application size
Global objects reduce memory because they are stored once
regardless of the number of links to it. Only one copy of a global
object is downloaded to the terminal.
