Each Scriptlet has access to three global objects in addition to the standard automation environment. They are:
- theDiagram – an automation Diagram interface to the diagram on which the Scriptlet resides
- theElement – an automation Element interface to the Scriptlet artifact itself
- theInstance – an automation DiagramObject interface to the Scriptlet artifact itself

How to use Scriptlets in EA 16?
- Drag-drop the Scriptlet element from the toolbox.
- Double click on the artifact to open the scripting pad.
- Edit the script as required.
- Reload the diagram to run the script automatically or right-click on the Scriptlet element and choose ‘Run Script’ from the context menu to run manually.
- Multiple Scriptlet elements can be used on a single diagram and, the Z-order of the Scriptlets on the diagram determines the order in which they are executed.
- Scriptlets are model-based and therefore the same Scriptlet element can be used on multiple diagrams.
Using Scriptlets in MDG Technologies
- Scriptlets can be incorporated into the definition of an element stereotype, as part of a Profile in an MDG Technology.
- Scriptlets can therefore be used to make on-the-fly changes to an element’s properties and presentation.
- To add a Scriptlet to an element stereotype, create an attribute named ‘_scriptlet’ within the element used to define the stereotype, and enter the script code into the ‘Initial Value’ field of that attribute’s properties.
