Great stuff!

A few comments on the tutorial:

Probably worth mentioning up front that a game wouldn't normally be a  
document-based application (and say at the end what would be  
different to use a non-document application template).

Rather than editing the pbxproj file manually:
   Targets inspector -> rubyrocks -> Info.plist Entries -> Document  
Types -> Document Class

I couldn't see any instructions for binding GameView.game to the Game  
instance (File's Owner) in Interface Builder.

The instructions for adding the 'game' outlet aren't as detailed as  
the result of the instructions in Interface Builder.

You can just use [a,b,c,d] instead of OSX::NSRect.new(a,b,c,d)  
(similarly for NSPoint), unless you want to hang on to the object and  
use .x, .y etc.

The moveWithBounds_ and initWithPosition_ methods etc don't need a  
trailing underscore.

The model objects (Sprite and descendents) can be plain Ruby objects  
rather than NSObject descendents. This means you can use a normal  
ruby initialize method (instead of .alloc.initWith...).

Jonathan

that's ok now, however when i do ;

the appearance of the buttons doesn't change, i've seen an appearance =20=

change only in awakeFromNib (in Interface Buider i did set all the =20

because i want to disable the buttons when a long time action.

When do you execute this line? You should do it inside awakeFromNib,  
since before that method is called the buttons will not be set from  
Interface Builder.

i.e., you must make the array assignment in awakeFromNib

[Rubycocoa-talk] Array of NSButton ???

[Yvon T. <tho...@fr...>]

in my gui i've a lot of NSButtons i've arranged theme into an Array :

     @buttons = [@nonVideButtonGauche, @uniqueButtonGauche,  
@fusionButtonGauche, @loadButtonGauche, @nonVideButtonDroite,  
@uniqueButtonDroite, @fusionButtonDroite, @loadButtonDroite]


if i do (by the end of awakeFromNib) :


   def enableAllButtons
     @buttons.each { |b| p b.class.to_s}
   end

i get "NilClass" for each NSButton

however doing :

   def enableAllButtons
     p "@nonVideButtonGauche " + @nonVideButtonGauche.class.to_s
     p "@uniqueButtonGauche  " + @uniqueButtonGauche.class.to_s
     p "@fusionButtonGauche  " + @fusionButtonGauche.class.to_s
     p "@loadButtonGauche    " + @loadButtonGauche.class.to_s
     p "@nonVideButtonDroite " + @nonVideButtonDroite.class.to_s
     p "@uniqueButtonDroite  " + @uniqueButtonDroite.class.to_s
     p "@fusionButtonDroite  " + @fusionButtonDroite.class.to_s
     p "@loadButtonDroite    " + @loadButtonDroite.class.to_s
   end


i get the right "OSX::NSButton" for all the  buttons :

"@nonVideButtonGauche OSX::NSButton"
"@uniqueButtonGauche  OSX::NSButton"
"@fusionButtonGauche  OSX::NSButton"
"@loadButtonGauche    OSX::NSButton"
"@nonVideButtonDroite OSX::NSButton"
"@uniqueButtonDroite  OSX::NSButton"
"@fusionButtonDroite  OSX::NSButton"
"@loadButtonDroite    OSX::NSButton"

does that means we have also to use a proxy class ?

[Rubycocoa-talk] can't convert String into Integer

[Yvon T. <tho...@fr...>]

i think this has nothing to do with RubyCocoa rather with ruby only,  
but in case of, because i'm stuck by this strange prob.

i have a hash like that :

@label_list={}

with only one key for the time being :

@label_list["BookmarksBar"]=[]

then, the value is an Array populated like that :

@label_list["BookmarksBar"] << folder.attributes["label"].gsub 
(/"(.*)"/, '\1')

then, i want to use this hash-value by :

if !@label_list["BookmarksBar"].include?(label_) # <= line 143


this works a number of times (above 20 times; it's within an each  
loop) until label_ =
"files" where i get :

/Users/yvon/work/RubyCocoa/BookmarksMerge/build/Development/BookmarksMer
ge.app/Contents/Resources/Controller.rb:143:in `NSApplicationMain':
NSApplicationMain - RBException_TypeError - can't convert String into

label_ are always strings...

I don't think so. However, it's possible that you could do the drive  
Interface Builder via AppleScript to create the classes as required.

You could probably also create a ruby script that parses the output  
from 'nibtool -c' (and other options) to create a skeleton .rb file.

Does Interface Builder have some kind of hook that we could modify to

You can do it manually in Interface Builder. You need to create a =20
subclass of NSObject with the appropriate name, and then instantiate =20
it. This is described in the Interface Builder help. I've pasted a =20
fragment of it below. You'll have to add the actions and outlet names =20=

manually too.

[Rubycocoa-talk] newbie question: how to instantiate ruby object in InterfaceBuilder

[Hunter K. <re...@gm...>]

Hiya, I'm fairly new to Cocoa programming.  I'm using XCode +
Interface Builder, and have been working through "Cocoa Programming
for Mac OS X".

I'm a long time ruby fan, and have started playing around with the
RubyCocoa bindings.  Ruby and Objective-C look like a really natural
fit, and the binding seems really good.

However, I'm having a problem figuring out what I assume must be a
pretty simple thing - how do I make a Interface Builder "see" my ruby
classes, so I can create an instance of it, and tie it into the nib
file?

For example, I opened up the simpleapp example.  Interface Builder can
"see" AppController and MyView.  However, in XCode, if I create a new
Ruby subclass of NSObject, I can't figure out how to tell Interface
Builder about this new class.  If it were Obj-C, I'd just drag the .h
file onto Interface Builder, but when I try that with the .rb file
Interface Builder flicks over to the sounds tab or something.

What do I need to be able to do to make Interface Builder aware of my
Ruby classes?

Cheers,

Hunter

This would cause the behaviour you're seeing. *Only* REXML::Element =20
should have NSOutlineViewable included. By including it at the top =20
level the strings you're returning as values are becoming converted =20
to OutlineViewProxy objects, which confuses NSOutlineView.

Yeah, you need to add it specifically to the Ruby class you are  
returning from the outline view (after requiring rexml first):

require 'rexml/document'
module REXML
   class Element
     include NSOutlineViewable
   end
end

I see you already have that in 'OutlineViewProxyClass.rb' so it  
should be fine.

By including 'to_nsobj' in the REXML::Element class you shouldn't  
need to call it explicitly. RubyCocoa looks for a 'to_nsobj' method  
when passing a Ruby instance to Cocoa. Also, since 'nil' evaluates as  
false in ruby, you could do:

if bookmark then
   children = bookmark.slave.get_elements("*")
   return children[index]
else
   return @folder
end

Ah, my fault. A copying-to-Mail.app error crept in.

This line from OutlineViewProxy#init:
    @slave = slave
should be
    @slave = slave.object_id

That should hopefully fix it.

OK, this is the problem. NSOutlineView doesn't retain the object  
returned from this method. Since REXML::Element is not derived from  
NSObject, the object NSOutlineView sees is a temporary proxy for the  
ruby instance. Since the proxy is temporary, NSOutlineView gets  
confused because it expects to see the same object later.

Here's a workaround for the moment (until there's a better solution  
in RubyCocoa core):

# Define helper class
class OutlineViewProxy < OSX::NSObject
   ns_overrides :init
   def init(slave)
     super_init
     @slave = slave
     self
   end
   def slave
     ObjectSpace._id2ref(@slave) # used to prevent GC cycle
   end
end

# One instance of helper class per plain ruby object being helped
module NSOutlineViewable
   def to_nsobj
     # This will be released with ruby instance is GC-ed
     @__nsoutlineviewproxy ||= OutlineViewProxy.alloc.init(self)
   end
end

# Include the helper module in REXML::Element
module REXML
   class Element
     include NSOutlineViewable
   end
end

# Now, in any of your outlineView methods that takes an 'item' argument,
# you must get at the real object by using 'slave' first.
# e.g.,

   def outlineView_isItemExpandable(aTree, bookmark)
     return bookmark.slave.has_elements?
   end

Let me know if that works for you.

How are these methods implemented, and what types of values are the  
items you are returning? They must be NSObject subclasses, and you  
must keep a reference to them somewhere - otherwise they will be  
garbage collected and things will go wrong.

Assuming that after these messages you are able to type commands to  
gdb, please type 'bt'<RETURN> and include the results in an email.

[Rubycocoa-talk] [XCode] GDB (debugger) and NSOutlineView

[Yvon T. <tho...@fr...>]

Hey all,

i want to show the content of an bookmarks xml file in a NSOutlineView.

i've done all the :
		@safTree.setDelegate(self)
		@safTree.setDataSource(self)
		@safTree.reloadData()

@safTree being the NSOutlineView

and also :

	def outlineView_numberOfChildrenOfItem(aTree, bookmark)
	def outlineView_isItemExpandable(aTree, bookmark)
	def outlineView_child_ofItem(aTree, index, bookmark)
	def outlineView_objectValueForTableColumn_byItem(aTree, tableColumn,  
bookmark)
	def outlineView_shouldEditTableColumn_item(aTree, tableColumn,  
bookmark)


after "@safTree.reloadData()" the root element is correctly displayed  
however, when clicking on it, i get the GDB (gnu debugger)

and no Ruby message at all;

the GDB console says :
warning: Unable to read symbols for
"@executable_path/../Frameworks/RubyCocoa.framework/Versions/A/RubyCocoa
" (file not found).
Program loaded.
sharedlibrary apply-load-rules all
Attaching to program:
`/Users/yvon/work/RubyCocoa/BookmarksMerge/build/Development/BookmarksMe
rge.app/Contents/MacOS/BookmarksMerge', process 2267.


and GDB underlines the line :
0x909bf120  <+0032>  lwz      r11,0(r2)

(seems to be asm which i don't understand...)

is it a way not to get GDB ?

also, after clicking, on root element in NSOutlineView, i get no call  
to either :
	def outlineView_numberOfChildrenOfItem(aTree, bookmark)
	def outlineView_isItemExpandable(aTree, bookmark)
	def outlineView_child_ofItem(aTree, index, bookmark)
	def outlineView_objectValueForTableColumn_byItem(aTree, tableColumn,  
bookmark)
	def outlineView_shouldEditTableColumn_item(aTree, tableColumn,  
bookmark)
only the GDB is launched....


if someone has experienced such thing...
