How to add element in ScrollView ?

[HugoJourdan]

Hi,

This might be a simple question, but I can't figure out how to add an element to a ScrollView.
I tried using the code snippet from the documentation, but I couldn't get it to work.

from AppKit import NSView, NSColor, NSRectFill
from vanilla import *

class DemoView(NSView):

    def drawRect_(self, rect):
        NSColor.redColor().set()
        NSRectFill(self.bounds())

class ScrollViewDemo:

    def __init__(self):
        self.w = Window((200, 200))
        self.view = DemoView.alloc().init()
        self.view.setFrame_(((0, 0), (300, 300)))
        self.w.scrollView = ScrollView((10, 10, -10, -10), self.view)

        self.w.scrollView.text = TextBox ((10,10,-10,20), "Text 1")
        self.view.text = TextBox ((10,10,-10,20), "Text 2")

        self.w.open()
