Response to: Some changes
Hello p, Wooh, it's very hard for me to understand well what you say. I'm not an English native speaker, so, please, try to use only very basic words, so I can follow your ideas. "I see a neat professional subject line, "some changes". This indicates that you have work group experience". Just one thirty years ago (yes, 30). "Working hypothesis : "displayIfNeededIgnoringOpacity" method might need some interesting knowledge navigation to track down the description of." I''ve already told you of an application which you can browse the doc with. It's MarshmallowLibrarian. But since sherlock has been greatly improved with the last OS update and MarshmallowLibrarian tends to crash repeatedly on my computer, I use Sherlock (just drop the developer folder on to the main Sherlock page), index it, and give it an enclosed string to search into documents. Another good way to learn efficiently is to browse all the examples (see composite lab and sketch for images). Whenever you find a method you don't know, use find in PB with options frameworks only. You'll get all references to the searched method. Then browse the corresponding doc. There are also shortcuts to do it. Another excellent way to learn is to subscribe to Cocoa Apple mailing list. Read, read, read it first, then ask people. And download examples when people give you a link to. displayIfNeededIgnoringOpacity is well described in NSView: Acts as displayIfNeeded, except that this method doesn't back up to the first opaque ancestor-it simply causes the receiver and its descendants to execute their drawing code. The April Developer Tools CD is online now for all ADC members. If you have, as I do, a slow connection, you'd better buy it (20$). It's an about 243 Mb download. I've bought it on April 24th and received it today (I'm in France). The main advantage is that you have the whole documentation updated (no need to go to Apple site every two lines of code). Michèle

  "...use only very basic words, so I can follow your ideas..."
  
  I've found putting ideas in shorter paragraph can also work to get through language barriers.
  
  """Just one thirty years ago (yes, 30)...."
  
  I have been a scholar for 17 years and am afraid the work group has developed while I have learned to work alone not with people. I worry about my choices and other lives I might have lived. I suspect most people's work group experience is "getting along with powerful people". I've had that with my thesis advisor because I gave him power by investing with him my life time. I want another sort of work group experience... Don't know what that could be.
  
  Please compare sherlock indexing string search to Help Viewer. As soon as I asked this question, I imagined your answer. Help Viewer doesn't have find but an html browser does and probably string search gets you right to the instance of the words.
  
  MarshmallowLibrarian:
  
  I downloaded MarshmallowLibrarian, enough documentation on web page, the pictures and comments on this page were reassuring and seemed enough, so I turned web page into pdf file. I used sherlock 2 internet channel to find it.
  
  "...browse all the examples (see composite lab and sketch for images). "
  
  I couldn't understand this. By "browse" do you mean use a web browser such as netscape or internet explorer? If that is what you meant by browser, I understood that part. I think I might drag the example folder into sherlock and augment web browser to give meaning to the phrase "browse all the examples" to indexed enclosed string search examples. But, "see composite lab and sketch for images" confuses me still. Maybe sketch is an application and is also "composite lab" an application?
  
  In making guesses, I ease your language embarrassment. It is easier to read than write a foreign language (at first) and allowing you to answer yes or no will give you great energy, just like that Chinese fellow I asked about nobel level stuff with "do I understand you to mean....".
  
  "...use find in PB with options frameworks only..."
  
  I know command 7 finds everything, both my code and frameworks. Now I will look for setting options. Very good.
  
  "... There are also shortcuts to do it. ..."
  
  Knowing that something is out there to find is valuable to me. I will go find shortcuts.
  
  I've long ago subscribed to Cocoa Apple mailing list, but I am a bit scared of it, as yet. I peek at it and Maya list, but shyly work Mike's and Maya's tutorials, so far. I'm not so shy on this thread, though.
  
  " ... download examples when people give you a link to. ...."
  
  This gets rid of my shyness a bit. I can play with examples and not be embarrassed I don't know the language.
  
  "displayIfNeededIgnoringOpacity is well described in NSView"
  
  And my putting together sherlock indexing and search with enclosed string would buy me not having to look through the huge NSView as Help Viewer would have. Perhaps Apple wishes to force new programmers to read introductions, see their doc organization, and so don't put in a find string or jump to method in Help Viewer.
  
  The phrase you chose out of NSView seems clear enough. Thank you.
  
  "April Developer Tools CD ..."
  
  I get the cd mailing to get perpetually embarrassed that I am often too scared to look at it. My ultimate goal is to get so many cd's that I shall have to learn the respect for hypertext and search strategies you have. I believe that April mailing had general os 9 including tools, but May mailing has os x specific tools. Now, I have more courage to look inside and see.
  
  Thank you!

  Hello p (what's your first name please, p sounds very mathematical to me),
  
  By "browse" do you mean use a web browser such as netscape or internet explorer?
  
  No, excuse me, My English is very basic. I mean, read it thorougly, cut the parts of code you thing you understand and use it in your own application to experiment with.
  
  Sketch and Composite Lab are code examples from Apple. You find them and a lot more in the Developer folder, Examples, AppKit. The Developer folder is at the first level of your hard disk.
  
  As for the new PB, try it. You can customize the editors, use gcc 3. And what's unvaluable you have the up-to-date documentation. Personnally, I was at the border of nervous breakdown with the ever mentioned "description forthcoming" each time I needed more details on a method, a class or even a topic.

  www.maccentral.com has Jobs keynote saying it has this multithreaded feature like Marshmallow librarian has. I suspect that feature is much more than being able to search while indexing. I'd like Apple to eventually tell me something deeper about that multithreadedness being a good feature.
  
  I'm going to fool with Marshmallow librarian.
  
  I think there are general things I don't understand about indexing, whether with sherlock or Marshmallow librarian. Where, for example, is the index saved or is it saved?
  
  I installed the May 2002 cd mailing mac os x developer tools. There was also a disk with developer tools in April. So, to make an April fools joke, I might be fooled as to which was the April tools. They usually have distinct things in different months and two months of tools is surprising. So, I may really be fooled.
  
  I copied and recompiled and old project in Applescript and then did the "Variables Inside Cocoa Objects" of 04/12/2002 in the new PB. The readme on the May cd mailing tools said that headers were precompiled and so builds were faster. I think they were.
  
  Exciting.

  Hello Paul,
  
  The indexes you create with MarshmallowLibrarian are saved in Users/Library/Application Support/MarshmallowLibrarian/Index. Whenever you launch the application or a saved file, the program loads the indexes.
  
  As for Sherlock, I think the indexes are encoded into the com.Apple.Sherlock.plist file which is located in Users/Library/Preferences folder.
