Hi, In the same way that this tutorial (http://developer.apple.com/library/mac/#featuredarticles/UsingMacRuby/_index.html), I try to implement a NSOutlineView controller in ruby to make a simple tree in the left part of a window. I read the documentation of NSOutlineView, tasks and I understand I have to write at least four methods in my controller class: • – outlineView:child:ofItem: • – outlineView:isItemExpandable: • – outlineView:numberOfChildrenOfItem: • – outlineView:objectValueForTableColumn:byItem: My questions are: 1) what kind of object I have to use in ruby to fit with outlineView structure? If I understand I need a structure like: Parent_1 : child 1, child 2 Parent_2 : no child Parent_3 : child 1, child 2, child 3 2) Is a Hash like this: Hash[ "Parent_1" => ["child 1", child 2"], "Parent_2", Parent_3 => ["child 1", "child 2", "child_3"]] can be the solution? 3) where I can find this kind of information: the mapping between ruby data structure and NSObject data structure (for future use)? 4) and the last one: I think I do not understand what is item in the last method: – outlineView:objectValueForTableColumn:byItem: item: An item in the data source in the specified tableColumn of the view. So, if I want to make a simple tree, I should have just one column, and then item should be Parent_x or child_x: Is it right?
