[MacRuby-devel] How to use NSIndexSet with tableView data

[Pixoo]

That doesn't match what I need.
Ok, here is what I have :

My data is the @items variable which is an array of objects.
My tableView is @tableView.
The action is a reaction to a click on a remove button after a selection in
the table.

What I want to do is something like this :

def removeItems(sender)
  indexes = @tableView.selectedRowsIndexes
  @items.delete_at(indexes)
  @tableView.reloadData
end

But I can't get a way to make it work.
