[MacRuby-devel] Is this the right list?

[John Shea]

textView seems rather tedious compared to textField to me.

Here is what I do (which does work when the view is made not editable):

class Controller
	attr_writer :text_view #linked to the IB textView on your window
	
	def awakeFromNib
	  replace_all_range = NSRange.new(0, @text_view.textStorage.length)
	  @text_view.replaceCharactersInRange(replace_all_range,  
withString:"a new string")
	end

end

I saw this originally when learning Ruby / Cocoa  in Brian Marick's  
RubyCocoa book - which is available at the moment as a PDF (it has not  
been released yet to paper I believe) from the Pragmatic Programmers.
Both Marick's and Hillegas's books are important reads for the  
beginning (eg me) macruby programmer.

Cheers,
J
