[Rubycocoa-talk] Is there an elegant way to get a reference to a instance var created by ib_outlets in a subclass?

[Eloy D. <elo...@gm...>]

Hello,

Like the subject says :)
I'll give an example of what I would like to be able to do:


class SomeClass < OSX::NSObject
  def self.active_table_view(tableViewName)
    ib_outlets tableViewName
    # Here I want to create a reference to the defined outlet
    instance_eval "@tableView = @#{tableViewName}"
  end
  def awakeFromNib
   # So that I could now do stuff like:
    @tableView.setDelegate(self)
  end
end
class SomeSubClass < SomeClass
  active_table_view :someTableView
end


At the moment I've hacked around it and it works,
but it should be possible to do it in a better way right?....
The hack I use now is like:


class SomeClass < OSX::NSObject
  def awakeFromNib
    # Loop through the instance variables and check for a NSTableView instance.
    # When found assign it to the instance variable @tableView.
    # Is this the way to do it? Or is there a way to intercept the
symbol passed to ib_outlets?
    instance_variables.each do |obj|
      instance_eval "
        begin
          if #{obj}.isKindOfClass(OSX::NSTableView)
            @tableView = #{obj}
          end
        rescue
        end
      "
    end
    @tableView.setDelegate(self)
  end
end

Cheers,
Eloy.
