Observable label provider for EMF elements ? [message #1152923] Thu, 24 October 2013 08:57 Go to next message

Hello,

I have a table viewer which is displaying EMF elements (contained in a list). I have set-up the content provider which works fine (the viewer gets updated when an element is added/removed from the list).

Now, what I would like to have is that the table (which only has 1 column) should display some text representing the element (something similar as what toString() is doing). So, the text is in fact taking all properties of the element. What I want is that whenever an element is modified, the corresponding entry in the table should be updated.

I could create an ObservableMapLabelProvider which maps to all features of my elements but and override the getText() method:
1) This is rather annoying to do
2) This is even impossible in my case since the elements can be of different types (with a common base class).

I was wondering if it exists a similar class as the ObservableMapLabelProvider excepts that it observes ALL features of the elements.

What I'm doing now to solve this problem is using a standard LabelProvider and registering a listener on my EMF model. When a change occurs in the list, I update my table viewer. But I would prefer to stick to databinding for that instead.

Thank you

You can use AdapterFactoryLabelProvider if you have the Edit code generated for your model.
