How to make a view aware of selection in another view [message #291727]

Hi,

I have two views showing table viewers. The content of view #2 depends
on the selection in view #1. I'd like to use the
ISelectionProvider/ISelectionListener approach for notifying view #2
about selection changes.

View #2 registers itself via getSite().getPage().addSelectionListener.
My question is: how can I register view #1 as an ISelectionProvider? (I
don't want to use getSite().setSelectionProvider because I don't want
the view to be the _only_ selection provider available.)

TIA
Martin

It shouldn't be a problem. If your view should provide a selection
provider, set it with getSite().setSelectionProvider(...). That sets
the selection provider for the view only.

When a part becomes active, the page switches to that part's selection
provider, as stored in the site.

Then changes in view#1 selection should be fired to view#2.

Cant view #2 listen to selection events, and pay attention to only the
ones coming from view #1?

That's a good way to do it ... but I think Martin was concerned if he
used setSelectionProvider() that would be the only one for the page ...
but they're maintained per site.
