[Rubycocoa-talk] Problem with delegates

[Justin S. <sto...@gm...>]

I'm trying to port a simple objective-c application (from a book on
cocoa in os x) to Ruby in Xcode.  Basically the application takes a
line of text and then says the line (out loud).  This all works fine
but I'm having trouble figuring out how to do the delegate to make the
stop button disable itself when the app finishes saying the line.
Here's the code:

require 'osx/cocoa'
include OSX

class Speak < NSObject
    ib_outlets :textField, :stopButton
	
	def initialize
		@speechSynth = NSSpeechSynthesizer.alloc().initWithVoice_(nil)
		@speechSynth.setDelegate_(self)
	end
	
    ib_action :say do |sender|
		blah = @textField.stringValue()
		
		if blah.empty?
			return
		end
		
		@stopButton.setEnabled_(true)
		if (rand(10)+1) == 1
			@speechSynth.startSpeakingString_("I'm not going to say that")
		else
			@speechSynth.startSpeakingString_(blah)
		end
		
		NSLog("Have started to say: #{blah}\n")
    end

    ib_action :stop do |sender|
		NSLog("Stopping.")
		@speechSynth.stopSpeaking
    end
	
	def didFinishSpeaking(sender)
		NSLog("Finished Speaking.")
		@stopButton.setDisabled_(true)
	end
end


It compiles and runs fine.  The only thing that doesn't work is
didFinishSpeaking is not called by @speechSynth when it finishes
speaking.  Any ideas on what I'm doing wrong?

Hi,

The delegate method of NSSpeechSynthesizer is  
"speechSynthesizer:didFinishSpeaking:".
So try this:

   def speechSynthesizer_didFinishSpeaking(sender, success)
     NSLog(@"Finished speaking");
   end
