Reading created model [message #1224775]

Hi,

I have created an eclipse graphiti plugin, but now I wanna be able to click on a button and convert the model created with the graphical editor to text. The problem is: I can't find a way to read the model that is being created on the editor.

Is there a way to do that?

Thanks!

Hi Filipe,

not sure what exactly you are trying to do. The Graphiti editor works on an
EMF model in memory, which is created/maintained using an resource
set/editing domain inside the editor. You may use this resource set to
access EMF resources and EObjects.

On save the editor content/EMF model is persisted on disk.

Hi Michael, thanks for your reply!

I'll be more specific about what I want: when I create a Graphiti model (based on my ecore model), I wanna be able to click on a Eclipse menu item and run a handler that needs to access the ecore model with the contents of the diagram I'm working on. How is that possible?

Thanks.

Hey,

maybe I dont understand what you mean, but if you just want the elements from the
current diagram, you can call them via:

getDiagram().getChildren();

Now you are able to test the elements for their business object.

Hi,

I can do that from the diagram editor code, but I want to do that from the handler of a menu button (created using the commands extension point).

Is that possible?

If not, can I read the model from the file on disk after I save it with the editor?

Thanks.

Filipe,

best would be to synchronize with the editor if the menu entry is part of
the editor. You will need to get the currently active editor (instanceof
DiagramEditor, getActiveEditor on the currently active Eclipse page) and
from there you should be able to grab the diagram and its resource.

Maybe that's what I need. Unfortunately I'm having some import errors, and I don't know which packages I should install. I've installed the EMF SDK and the Graphical Editing Framework GEF SDK, but to no avail...

The packages that cannot be resolved are:
org.eclipse.emf.edit.domain.IEditingDomainProvider,
org.eclipse.ui.views.properties.tabbed.ITabbedPropertySheetPageContributor and
org.eclipse.gef.ui.parts.GraphicalEditorWithFlyoutPalette.

They are referenced indirectly when I import org.eclipse.graphiti.ui.editor.DiagramEditor.

Which packages should I install?

Thaks.

-- edit --

Just found a workaround: manually imported org.eclipse.ui.*; org.eclipse.emf.* and org.eclipse.gef.* in the project build path.

Filipe,

you will additionally need EMF Transactions SDK and EMF Validation SDK.

But I wonder why you get errors regarding Tabbed Properties classes and GEF
classes. Are you sure you have installed them correctly and use the right
target?

The erros appears when I import org.eclipse.graphiti.ui.editor.DiagramEditor.

I have EMF Model Transactions SDK and EMF Validation Framework SDK installed (I checked on Help->Install New Software...)

The target platform is Running Platform.

Hm, this should be part of the EMF SDK.
