binding gmf editor with workspace resource in eclipse runtime enviornment [message #654063]

Hello Community,
I am newbie to gmf based graphical editor generation. I am interested in tracing model<-> code inconsistencies in my project.

I have a code base from which i am generating model and displaying that with gmf based editor. In the model nodes I am using "qualified name" attribute which is actually representing string path to a particular file(java class) in the code base.I would like to use this attribute to trace a particular class. I would like to do the following

When I double click any particular node, I want to go to the particular class in a code base.

Can i implement this functionality while developing gmf based graphical editor? or else How can i do it? any pointers? Is there any running example available which i can have a look at?

regards
saad

Hi,

This is possible, you'll simply have to add an EditPolicy on your node. I think you should use an OpenEditPolicy, which listen to double-click events.

Hi Mickael,
thank you very much for your reply. Can you roughly let me know the process of how can I implement this. Do I have to extend that In code or in extension palette in plug-in? Is it GraphicalNodeEditPolicy you are talking about that listens double click events? Is there toy example available for this purpose (double clicking a graphical node and workspace resource (e.g.,file/java class) opens in a text edior )?
Thank you very much in advance for your help.

Maybe this link can help: http://wiki.eclipse.org/GMF_Newsgroup_Q_and_A#How_to_change_ an_attribute_of_an_object_when_clicked.3F

The trick is to implement a subclass of openEditPolicy that will perform the action you want when double-clicking on an EditPart, and to install it on your diagram. You should create an extensions plugin for your diagram to add this class, and provide an editPolicy contribution in its plugin.xml. I let you go ahead, googling for org.eclipse.gmf.runtime.diagram.ui.editpolicyProviders extension point.
