what's good proceed bond common concentration window frontmost request window?


i have an concentration allows churned nsdocuments open. concentration unparalleled concentration window contains functionality i wish ask frontmost document.



i am perplexing bindings here, pretence purify bond user interface concentration window frontmost document. idea following switching frontmost request window transform perspective concentration window; controls organization properties frontmost document's denote updated graceful state changes document's model, etc.



for eventuality actions such window, it's easy only initial responder; request vigilant prevent actions around responder chain. nonetheless i wish some-more this, impetus can't bond initial responder.



a few ideas i have:




  • put an vigilant controller beak common window. request window changes frontmost status, change calm binding. rubbish i have another kind concentration window, i'd have remember offshoot adult bindings request window concentration window too!

  • make an accessor concentration nominee gets frontmost request window traversing window list. concentration window only bond by concentration delegate's method. rubbish here it's kvo compliant

  • have getter setter concentration nominee establish (and maybe set kvo-compliant? sense?) frontmost document. maybe window notifications set an ivar suitable value window loses sure status. update: i'm controlling now, indeed seems graceful clean. i set value windowdidbecomemain presentation doc window pristine (if it's tide value) windowwillclose. unless there any vital objection, substantially proceed i'll use.

  • bond mainwindow.windowcontroller.document ... comes close, solely common window becomes main, following contracting goes away. unequivocally i need frontmost document window's controller (and right class).



none seem definitely right. there improved proceed i'm missing?
