#907: forKeyPath and valueForOutputKey don't appear to work in MacRuby -------------------------------------+-------------------------------------- Reporter: shaun@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- Description changed by martinlagardette@…: Old description:

I am new to MacRuby so I apologize if I have this wrong.

I am trying to access the patch values of a quartz composer controller object and I am running into some errors.

Here is a summary of the code:

class AppController

attr_accessor :testButton, :myQCView

def awakeFromNib

@test_btn = false

puts @myQCView.is_a? NSObject @myText.setStringValue("this is my value") @myQCView.setValue(txt, forKeyPath:"patch.text.value") puts @myQCView

end

# a test button def testButton(sender) if @test_btn @testButton.setTitle("test button") puts "test button activated" @myText.setStringValue("test content") @test_btn = false image = @myQCView.valueForOutputKey("quartz_image") puts "this is the image " + image if image puts "got the image" end else puts 'test button Stopped' @testButton.setTitle("stop test") @test_btn= true end end

The error message I get is:

It was indeed the issue. I was binding to the QCPatchController and not the QCView (I had an issue where I wasn't able to get the attr_accessor values to show up in interface builder and I went on a wild goose chase for a couple of hours until a MacRuby reinstall fixed the issue). MacRuby is not the issue. myThanks, Shaun -- Ticket URL: <http://www.macruby.org/trac/ticket/907#comment:3> MacRuby <http://macruby.org/>
