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

How about @text_view.setString("foo") or as @text_view.string = "foo" ?

Y'know what, that doesn't seem to work actually. No '<<' method, and setCharacters/setWords works, but nothing shows up.

:textview is linked to an NSTextView object via InterfaceBuilder. Now the purpose of this view is to work as the display for text coming from a MUD (Multi-user domain/dungeon). I have it set to noneditable but selectable. My above code doesn't work. I allow it to be editable, and the code does work. Is there a way to prevent user-editing but to allow my code to edit it?
Extract from Apple's Objective-C insertText: documentation:
This method is the entry point for inserting text typed by the user and is generally not suitable for other purposes. Programmatic modification of the text is best done by operating on the text storage directly. Because this method pertains to the actions of the user, the text view must be editable for the insertion to work.
You can do for instance
@text_view.textStorage << 'my text'
But be careful, text inserted like this ignores the current font attributes of the text view. You have to add them yourself.
