[MacRuby-devel] Problem with a window controller

[david kramf]

Thank you very much Andy and Jim
I followed your remarks , played  with the code and I am still surprised. It turns out that awakeFromNib is called before applicationDidFinishLaunching so there MyController is already initialized and has the correct window as the his instance variable. NSWindow has both a delegate protocol and a Controller class and so I called setDelegate and setController . Everything seems OK but the methods willLoad and didLoad are not called although clearly my class is both the delegate and the controller of my window . So I am still left asking what am I doing wrong (??).

Are there MacRuby code samples I can use. I read Lim,Chueng and McAnally book. I wonder where can I find more samples. I am also not sure I am doing everything correct with the IB . My blue box that represents MyController list "showWindow: " as a "Received Action"  , but I could not  connect it to any element of window draw in the XIB file.

class AppDelegate
    attr_accessor :window
    def applicationDidFinishLaunching(a_notification)
        puts " Insert code here to initialize your application"
        wCtrl = @window.delegate
        puts "no delegate" if wCtrl == nil
        win = wCtrl.window
        puts "win is nil" if win == nil
        puts "title of window is #{win.title}"
        ctrl = @window.windowController
        puts "no controller" if ctrl == nil
        puts "class of delegate is #{wCtrl.class}"
        puts "class of controller is #{ctrl.class}"
        puts "both are equal " if wCtrl == ctrl
        x = ctrl.showWindow
        puts "x class is #{x.class} " unless x == nil
        
        #puts "window nil " if win == nil
        #wCtrl.close
    end
end
class MyController < NSWindowController
    attr_accessor :window
    
    def initialize
        puts "in initialize"
        initWithWindowNibName("tow")
        #puts "after initialization window is #{@window.title}"
    end
    
    def routine
        puts "in routine"
    end
    
    #def initWithWindow(window)
    #   puts "in initWithWindow"
    #   super(@window)
    #end
    
    def awakeFromNib
        @window.setDelegate(self)
        @window.setWindowController(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
    
    def showWindow
       puts "in showWindow"
       super(self)
    end
    
    def close
        puts "in close window is #{@window.title}" 
        super
    end
    
end


at end of awake from nib. title is two
 Insert code here to initialize your application
title of window is two
class of delegate is MyController
class of controller is MyController
both are equal 
in showWindow
x class is MyController
