[news.eclipse.modeling.gmt] Re: [Epsilon] [Eugenia] Diagram Imp. Samples

[Louis Rose <louis@xxxxxxxxxxxxx>]

Hi Sami,

No problem.

I think in the Mindmap example, Threads are implemented as compartments 
on Topics. In turn, ThreadItems are implemented as compartments on Threads.

The layout option on the @gmf.compartment annotation defines the way in 
which items can be created inside a compartment. In the Mindmap example, 
ThreadItems are displayed using a list layout. Therefore, the annotation 
@gmf.compartment(layout="list") should be used with EuGENia.

I think the following Emfatic source should produce what you want, when 
the GMF diagram is generated with EuGENia:

@gmf
@namespace(uri="mindmap", prefix="mindmap")
package mindmap;

@gmf.diagram
class Mindmap {
  val Topic[*] topics;
}

@gmf.node(label="name")
abstract class NamedElement {
   attr String name;
}

class Topic extends NamedElement {
	@gmf.compartment(layout="free")
	val Thread[*] threads;
	
	@gmf.link(target="relates to")
	ref Topic[*] related;
}

@gmf.node(color="255,255,153")
class Thread extends NamedElement {
	@gmf.compartment(layout="list")
	val ThreadItem[*] threadItems;
}

@gmf.node(border.width="0")
class ThreadItem extends NamedElement {}


I hope this helps.

Many thanks,
Louis.
