[MacRuby-devel] Source List: NSOutlineView in a NSScrollView

Thank-you very much Watson for your SourceListViewBased example.
As usual, I have few questions:
1) Where did you find "isGroupItem:item" for OutlineView? I search in NSOutlineView Class Reference but I didn't find it!
2) I start from your example and I add a column to show a badge for each child. It's work, but there is still a small problem I do not understand:
Even if I set the size with interface inspector, the inline button is always the same width of the width of the column when I run the program.
For instance, the column's width is 70 and I set the button's width to 25. 

Thanks for reply

Some explanation and code:

I use the following method found on internet:
"First subclass NSTableCellView and add an IBOutlet for an NSButton and a @synthesize/@property statement for it. Then open the NSTableCellView which should have a badge in Interface Builder. Set it's class to your newly created subclass and add a button to it. Set the button style to "inline" and it's type to "switch".

Now select the TableCellView againa and connect the NSButton IBOutlet to your added button. That's it. You can now call e.g. [cellView button] setTitle@"123"]] to set the rows badge label to 123 or any arbitrary string."

So I append to your AppDelegate file the following new class, translated from the previous explanation in ruby:
class MaCellule <  NSTableCellView
    attr_accessor :iden
    def initialize
        @iden = NSButton.new

and I change one of your method as follow:
    def outlineView(outlineView,
        if (tableColumn.nil?|(tableColumn == outlineView.outlineTableColumn))
            if item[:type] == "group"
                # group
                view = outlineView.makeViewWithIdentifier("HeaderCell", owner:self)
                #puts item['name']
                view.textField.stringValue = item['name']
                # child
                # puts item["name"]
                view = outlineView.makeViewWithIdentifier("DataCell", owner:self)
                view.imageView.image = item['icon']
                view.textField.stringValue = item['name']
            return view
            if item[:group] == "group"
                #puts item["name"] + " 2 " + item["badgeValue"].to_s 
                view = outlineView.makeViewWithIdentifier("ButtonCell", owner:self)
                #puts view.iden.class
                if item["badgeValue"].empty?
