Re: [Rubycocoa-talk] Subclassing NSFormatter

[Satoshi N. <sna...@in...>]

Hi,

If you try "p objc", you will see it's an ObjcPtr object.

   #<OSX::ObjcPtr:0x50310d8 cptr=0xbfffafdc allocated_size=0 encoding=@>

You can deal with pointer arguments through the ObjcPtr class.

Actually I wrote a custom NSFormatter as follows:

class SingleLineFormatter < NSFormatter

   def stringForObjectValue(str)
     str.to_s.gsub(/\r\n|\r|\n/, ' ')
   end

   def getObjectValue_forString_errorDescription(objp, str, err)
     s = str.to_s.gsub(/\r\n|\r|\n/, ' ')
     objp.assign(s.to_ns)
     true
   end

   def isPartialStringValid_newEditingString_errorDescription(str,  
strp, err)
     s = str.to_s
     return true unless s =~ /\r\n|\r|\n/
     s = s.gsub(/\r\n|\r|\n/, ' ')
     strp.assign(s.to_ns)
     false
   end
end
