Can't set BoxLayout size

[Kensei.akita]

First of all, if they are some system diffrences, I work on Ubuintu 12.04, using actual Kivy version. My problem is unability to set layout size.

from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.boxlayout import BoxLayout
class TestApp(App):
def build(self):
    layout = BoxLayout(orientation='vertical', size=(200,200))
    btn1 = Button(text='Hello', size=(50,50), size_hint=(None, None))
    btn2 = Button(text='World', size=(50,50), size_hint=(None, None))
    layout.add_widget(btn1)
    layout.add_widget(btn2)
    return layout
TestApp().run()

Have You got any idea?

You must desactivate the size_hint:
> layout= BoxLayout(orientation='vertical', size=(200,200),
size_hint=(None, None))

I wrote something like that, and it didn't help. Did I understand , what You mean? 

def build(self):

layout = BoxLayout(orientation='vertical')

layout.size_hint = (None, None)

layout.width = 250

layout.height = 250

Pardon, layout=  BoxLayout(orientation='vertical',  size=(200,200), size_hint=(None, None)) also doesn't work

Yes it's working :)
But you also set a size to the button... why ?

You must decide if you want your boxlayout to set the size of the
children or not. Just remove all the size/size_hint from the button.
And, reread the documentation, and check the example. This is a standard
case used a lot everywhere :)
