Comment(by m...@…):

 Looks like this extension uses the RCLASS macro from ruby.h that doesn't
 seem to exist in MacRuby. Looks like its implementation specific? So,
 perhaps this isn't portable to MacRuby?

Comment(by martinlagarde...@…):

 I'd say the portability is kind of unlikely.

 `RCLASS` is a cast to `struct RClass`, which does not exist in MacRuby. We
 tend to think it is '''not''' a good idea to give access to the internal
 structures, especially since it's implementation dependent. Unfortunately,
 a lot of extension developers abuse this availability, most often
 unjustified though.

 What might be possible it to talk with the `narray` developer and try to
 see if there is another way to do whatever (s)he does with the class
 struct.

 Do we know how narray uses the RCLASS macro exactly? RCLASS could simply
 be emulated as `#define RCLASS(o) ((Class)o)'.

Comment(by martinlagarde...@…):

 After inspection in the code, the dev is using `RCLASS` to determine
 wether or not an object is an instance of `NArray`:
 {{{
 #!c
 static void
  na_check_class_narray(VALUE v)
 {
   if (TYPE(v) != T_CLASS) {
 rb_raise(rb_eRuntimeError, "class required");
   }
   while (v) {
 if (v == cNArray || RCLASS(v)->m_tbl == RCLASS(cNArray)->m_tbl)
   return;
 v = RCLASS_SUPER(v);
   }
   rb_raise(rb_eRuntimeError, "need NArray or its subclass");
 }
 }}}

 We do not use `m_tbl`, so this cannot be emulated :-(.

 I am looking for a solution right now. We do have an equivalent of what is
 being done, but it is totally different and would require ugly `#ifdef
 MACRUBY` etc. Instead we'd rather find a solution that can be used with
 ruby and macruby :-)

[MacRuby-devel] calculate table row height

2010-06-21 Thread niedhui 
Hello,I'm new to cocoa and macruby,
  I want to start a tweetie-like app to learn macruby & cocoa, when display 
status list,I use NSTableView,and I must calculate the row height with `def 
tableView(table,heightOfRow:row);end` myself ,right? After googled  a while,I 
found the way  ,like this:


framework 'cocoa'
class String
  
  def height_with_width(width=100)
  
attributes = {}
attributes[NSFontAttributeName.to_sym] = NSFont.fontWithName("Lucida 
Grande", size:12)
attributes[NSParagraphStyleAttributeName.to_sym] = 
NSParagraphStyle.defaultParagraphStyle
  
text_storage = NSTextStorage.alloc.initWithString(self)
text_container = 
NSTextContainer.alloc.initWithContainerSize([width,1000])
layout_manager = NSLayoutManager.alloc.init
layout_manager.addTextContainer(text_container)
text_storage.addLayoutManager(layout_manager)
text_storage.addAttributes(attributes, range:NSMakeRange(0, 
text_storage.length))
text_container.setLineFragmentPadding(0.0)
layout_manager.glyphRangeForTextContainer(text_container)
layout_manager.usedRectForTextContainer(text_container).size.height
  end
end


puts "a".height_with_width#15
puts "b".height_with_width#15
puts "ab".height_with_width   #15
puts "中".height_with_width#18
puts "ak中".height_with_width  #19
puts "ak中".height_with_width(1)  #15+15+18


because the chinese characters, the height of a line is diffence, I want it to 
be same ,like all return 19 , How Can I Fix This ? HELP!___
