Re: [Rubycocoa-talk] Can't "assign" an NSError to an ObjcPtr

[Wolfgang K. <kit...@ka...>]

Hi,

  Thanks due to your hints, the little test is now working. I changed my error generating method so, that it returns the NSError as it would be done by the brigde by converting the pointer to an additional retrun value:

require 'osx/cocoa'

class Contr < OSX::NSObject
  include OSX
  
  ib_action :trigger
  
  def generateError
    # simulate an error generating NS method
    error = NSError.alloc.initWithDomain_code_userInfo(
                  NSString.stringWithString('myDomainError'), 
                  4711, nil)
    # return NO and the constructed NSError
    return 0, error
  end # generate_error
  
  def trigger(sender)
    #errorPtr = ObjcPtr.new(1000)
    myresult = Array.new 
    myresult = generateError
    successful = myresult[0]
    error = myresult[1]
    unless successful == 1
      a = NSAlert.alertWithError(error)
      a.runModal
    end # unless
  end # trigger
end

  Many thanks to your appreciated help and best regards
