add a listener to a diagram element [message #1726631] Tue, 15 March 2016 09:26 Go to next message

Hi everybody,

For my project I have to listen to an element of a diagram an do some actions when the user clic or modify something on it.
For exemple when a field of an element is changed I want to automaticly change the value of another field. Do you know how to do that ?

Another thing I need to do (more complicated I think) is to get the layout position of an element (x and y) on the diagram and store those values on a field of it. For exemple if I drag the element on the diagram from position x=50, y=50 to x=100, y=100 I need that field of this element to automaticly change to x=100 and y=100.
I tried to modify the .aird file but it makes the diagram crash.

Is this something possible to do with Sirius ?

Thank you !
Alex

After some research It seems like it is possible to do what I need with the GMF Runtime plugin, the problem is that I have absolutely no idea on how to access that plugin with a Sirius diagram. Maybe I need to create and open the diagrams programmaticly ?

Hi,

Sirius is based on GMF, and GMF based on GEF, then you can API of these
frameworks also.
For your need you can use a precommit, i.e. a ResourceSetListener, to
update some model elements according to some changes. See [1]

Best Regards.

Thanks for your reply,

I also found this post with approximately the same question as mine : https://www.eclipse.org/forums/index.php/t/1068712/

The answer says that it's possible to use the org.eclipse.sirius.diagram.ui.business.api.view.SiriusGMFHelper.getGMFNode(DDiagramElement) method to do it.
As I am not really familiar with Siruis I don't know witch solution is the best (between the pre-commit and the helper) and I don't kwow how to get the DDiagramElement programmaticly. Do you have an idea ?

Alex.

Hi Esteban,

Could you please elaborate more on registering the listeners as an extension?

- Should we add the extension in the EMF project plugin or to the Sirius (design) project plug-in ?

- What is the Editing Domain ? is it our EMF project ?
<extension point="org.eclipse.emf.transaction.listeners">
    <listener class="org.eclipse.example.MyListener">
       <editingDomain id="org.eclipse.example.MyEditingDomain"/>
    </listener>
</extension>

Thanks,
Parsa
