Hi guys,

I want to set multiple roots for my treeviewer.

My program uses AdapterFactoryContentProvider as the tree viewer content provider but I was using single root.

Now when I wanted to add multiple root I knew that I should use ArrayContentProvider

is there something like this in EMF or I should adapt all previous code to the jface ArrayContentProvider ?



Thanks

You can create an org.eclipse.emf.edit.provider.ItemProvider and use
that as input to the view. In the constructor you can specify the
collection of objects you want as roots displayed in the tree view.

Thanks Ed,
I already have org.eclipse.emf.edit.provider.ItemProvider created for all my classes and that was used by adapterfactorycontentprovider.


In which constructor you mean ? can you please clarify this point .


Thanks,
becks

Are you perhaps mixing up ItemProviderAdapter, the base class for all
your generated item providers, with ItemProvider? I'm pretty sure
ItemProvider(Collection) will provide what you need.

It seems that I was mixing them up.
Now, I got your point, and I'll give it a try and get back if there is something else


Thanks a lot Ed.


Cheers,
becks
