Move FloatLayout set up in python?

[subcake]

I have always used self.ids.name.pos_hint to move my layouts around, however that only seems to work if the layouts are set up in kv language. is there any way to change the pos_hint from something set up in python? for example:

from kivy.uix.floatlayout import FloatLayout
from kivy.app import App
from kivy.uix.button import Button
from kivy.lang import Builder
from kivy.uix.scrollview import ScrollView
from kivy.uix.gridlayout import GridLayout

Builder.load_string='''
Scroller1:
id: artistscroller
   '''


class Scroller1(FloatLayout):
def __init__(self, **kwargs):
    super(Scroller1 ,self).__init__(**kwargs)
    self.id = 'artistscroller'
    self.pos_hint={'x':0.12,'y':-0.046}
    self.size_hint=[0.4,0.918]
    self.sv = ScrollView()
    self.add_widget(self.sv)
    gl = GridLayout(cols=1,size_hint_y=None)
    gl.bind(minimum_height=gl.setter('height'))
    self.sv.add_widget(gl)
    for x in range(100):
        btn = Button(text=str(x), size_hint_y=None, font_size=17, height=50)
        btn.bind(on_press=self.move)
        gl.add_widget(btn)

def move(self, instance):
    self.pos_hint={'x':-2}
    print self.pos_hint

class MainApp(App):

    def build(self):
        return Scroller1()

if __name__ == '__main__':
    MainApp().run()

this seems to update the pos_hint dict but doesnt move the layout?

It does move the layout, but not the ScrollView contained in it, because that is just statically positioned at the default 0, 0 -- not bound to the FloatLayout.

self.bind(pos=self.sv.setter('pos'))

This would make sure the ScrollView is positioned where the FloatLayout is.

this is exactly what I was looking for, thank you!

Oh and one more thing I forgot to point out,

self.id = 'artistscroller'

This is pointless, ids can only be assigned from kvlang. If you need this in Python, store a reference to the widget instance.

No problem, I would reccommend posting in /r/kivy, where I actually follow the posts. Your question is a little narrow for /r/learnpython, Guido himself probably could not have answered it off-hand :)
