Dear readers,
I have an EMF-based RCP-application that was originally generated using the genmodel-generator. The application thus has EMF.Edit end EMF.Editor components. When I run the application, I basically have an editor and a property sheet. When I select an object in the editor, the property sheet shows its properties, as expected.
Now I added a custom view part that contains a Tree viewer. Essentially the code is as follows:
public class MyCustomViewPart extends ViewPart
(...)
private ComposedAdapterFactory adapterFactory = new ComposedAdapterFactory(ComposedAdapterFactory.Descriptor.Registry.INSTANCE);
(...)
public void partActivated(IWorkbenchPartReference arg0) {
(...)
treeViewer.setContentProvider(new AdapterFactoryContentProvider(adapterFactory));
treeViewer.setLabelProvider(new AdapterFactoryLabelProvider(adapterFactory));
treeViewer.setInput(editingDomain.getResourceSet());
(...)
}
public void createPartControl(Composite parent)
{ (...)
getSite().setSelectionProvider(treeViewer);
(...)
}
When I now select an object in the tree viewer of MyCustomViewPart, the property sheet remains empty. When I activate the editor and select an object in the editor, the property sheet shows the proprieties of the selected objects.
Can anyone please give me a hint why the property sheet remains empty if I select an object in the tree viewer of my MyCustomViewPart?
Thank you very much for any help,
Christoph

Christoph,
I would guess that your view part needs to implement ISelectionProvider...

Hmmm. One would hope so yes...

I see. Note that the generated editor implements getAdapter to create
the appropriate properties view implementation, so you'd need to do that
too for your viewer...

Hopefully that's a good hint...
