Hello,

I try to integrate graphiti in an E4 application.
I use compatibility layer.

i wrote an E4 handler to open a diagram in my editor.

public class MyHandler {

	@Execute
	public void openEditor(EPartService partService,
			MApplication application, EModelService modelService) {

		MInputPart part = MBasicFactory.INSTANCE.createInputPart();
		part.setLabel("Editor");
		part.setCloseable(true);
		part.setContributionURI("platform:/plugin/org.eclipse.graphiti.ui/org.eclipse.graphiti.ui.editor.DiagramEditor");
		part.setInputURI("my diagram path");
		List<MPartStack> stacks = modelService.findElements(application, null, MPartStack.class, null);
		stacks.get(0).getChildren().add(part);
		partService.showPart(part, PartState.ACTIVATE);
	}

}



When i perform the action a part is open, but the tab is empty.
Does anyone already try to do that ?

Thanks.

Hi keersbulik,

Did you achieve the Graphiti-e4 integration works fine? I'm currently trying with the same issue and the part shows a blank editor. I'm using compat layer too.

Thanks,
Eduardo Fernández.

To open an IEditorPart you need to use the standard compatibility layer methods, either on IDE or IWorkbenchPage. If you want to see the behind-the-scenes work to open an IEditorPart in the model, track down how the WorkbenchPage and EditorReference create a CompatibilityPart/CompatibilityEditor to host the IEditorPart.

Hi Paul,

Thanks for your answer. Finally I decided to develope my app using Eclipse RCP because I found hard to use all the components I needed (graphiti, xtext, ...) in the app with e4. When e4 1.0 is released I will try this framework.

Hi keersbulik,

Did you manage to integrate graphiti with e4?

Paul, can you explain a little more about your idea? It's been 8 months now. Do you think there's an easier approach?

I am right now struggling with this approach. Any suggestions or comments will be highly appreciated!

Regards,
Johnny

Basically the problem with Graphiti is that it depends on GEF which is dependening on org.eclipse.ui.workbench.
That package requires your application to run with the compatibility layer, which supplies a re-implementation of org.eclipse.ui.workbench on top of "4.x".

So until GEF (and Graphiti) has been migrated/rewritten to be "pure 4.x", you need to write your editor the old 3.x way, which ensures that the "compatibility layer" is pulled in.

There's a bug 372171 for GEF which you may want to vote for... Not much has happened in the bug so it would be great to push it to make sure GEF moves along...
