Reading Diagram Properties

Diagram Properties control the way the GraphElements are displayed in MagicDraw.

General Case

Here is a sample code that shows how to get the Diagram Property, according to the key "USE_FILL_COLOR":

DiagramProperty property = graphicalElement.getProperty("USE_FILL_COLOR");

Reading a Font Property

The value of the Diagram Property created for a Font Property correspond to the Font Name.
The Style and the Size of the Font are EAnnotations of the Diagram Property.
Here is a sample code that shows how get the Style of the Font:

int style = DiagramProperties.getFontStyle(graphNode);

This will return:

'0' for 'Plain'
'1' for 'Bold'
'2' for 'Italic'
'3' for 'Italic Bold'

Here is a sample code that shows how get the Size of the Font:

int size = DiagramProperties.getFontSize(graphNode);

Reading a Choice Property

The value of the Diagram Property created for a Choice Property correspond to the Choice itself.
The Choices List is an EAnnotation of the Diagram Property.
Here is a sample code that shows how to get the possible Choices List of the Choice:

List<String> choices = DiagramProperties.getChoices(graphNode, "LINK_LINE_STYLE");

Reading Diagram Context

A Diagram Property context allows you to find the context of the diagram.
Here is a sample code that shows how to get the Element context:

String contextId = diagram.getProperty("context");

	if(contextId!=null && diagram.eResource()!=null) {

	EObject context = diagram.eResource().getEObject(contextId);

}
