[NewB]How to open a titled document

hey all,

that's the first time i'm doing a (Ruby)Cocoa Document application.

by inpecting the example "RubyRaiseMan" i'm able to open an untitled 
document.

however i'd like to automatically open a document on the desktop, if 
any, i want to give a name automatically.

i did :

          @doc_win.setTitle(f)

if i print out this title using :

p "@doc_win.title=#{@doc_win.title}"

i get the correct title (ie f) BUT the window didn't change is name 
even with an #oc_display (ruby equivalent to Obj C needsdisplay...)

also i'd like to have this document opening the application, as usal, 
when double clicking on it ?

i know i need something like :

    @appleEventManager=OSX::NSAppleEventManager.sharedAppleEventManager
     
@appleEventManager.setEventHandler_andSelector_forEventClass_andEventID(
self, 'openDocumentWithContentsOfURL:display:error:',  'TEXT'.unpack
('N')[0],  'TEXT'.unpack('N')[0])


because i was able to use getURL but here i don't know what to put as 
a Selector and eventClass ???

best,

Yvon
