EMF Show model attributes as rows in a table/tree [message #664028]

Hello

I'm quite new to EMF and don't know my way around here, so sorry if this question has been answered before - I couldn't find it using the keyword search.

Lets suppose I have a model class "Configuration" with ~15 attributes. The class also contains references to "SubConfiguration" classes, also ~15 attributes each.

Now, I know how to use the generated edit code to create a table/tree viewer with ~15 columns for a table viewer: put 15 columns in a table viewer and implement getColumnImage() / getColumnText() in the respective item providers.

But - a table with 15 columns is all but fun to work with. I would like to get a tree with 2 columns, attribute name in the first and value in the second column.

How can I get a content provider that takes the EMF classes and returns its attributes as children? Do I have to write it myself or is there some implementation in EMF that is either ready to use or can be generated?

Thanks!

Martin,

Via the GenFeature of the GenModel you can instruct the generator (via
the Children property) to support attributes as children, so that would
be a starting point at least...
