[news.eclipse.modeling.gmf] Re: graphdef.editor -> Problems when generat

[erdtek@xxxxxxxxx (Nikolay Georgiev)]

Hi Alex,

I downloaded the last version of the editor, but I got an assertion 
exception when trying to Open the "graphdef.gmfgen" file:

=====
org.eclipse.core.runtime.AssertionFailedException: assertion failed: 
	at org.eclipse.core.runtime.Assert.isTrue(Assert.java:109)
	at org.eclipse.core.runtime.Assert.isTrue(Assert.java:95)
	at 
org.eclipse.ui.part.MultiPageEditorPart.setActivePage(MultiPageEditorPart.java:695)
	at 
org.eclipse.ui.part.MultiPageEditorPart.createPartControl(MultiPageEditorPart.java:287)
=====

Can I ask you something about this graphdef editor?

I want to implement a GUI editor, and for most of the elements/widgets I 
want to have as properties their X and Y coordinates, Height and Width. 
How can I program this? As far as I understood from your response in this 
article 
(http://www.eclipse.org/newsportal/article.php?id=13363&group=eclipse.modeling.gmf#13363) 
the graphdef editor can be used as an example of such properties, and 
that's why I want to start it and see how they are implemented there. 
Unfortunately I couldn't understand you when you say that one should 
implement "domain model listener" and overwrite the "refreshBounds()" 
method. What is domain model listener and where is this method?

I have also tried this with "model.eSet(e, model);", but this didn't work 
out:
