Hi, In MyController (copied below) the awakeFromNib is called but the other methods are not . Can someone explain me what the problem is ? Thanks, David class MyController < NSWindowController attr_accessor :window def awakeFromNib @window.delegate = self puts " at end of awake from nib. title is #{@window.title}" end def windowWillLoad puts "window will be soon loaded" end def windowDidLoad puts "window loaded" end def windowTitleForDocumentDisplayName(displayName) "Hello World" end
