Tkinter - Add scrollbar for each LabelFrame

I'm trying to make a UI using Tkinter and I'm having problems to put three Scrollbars inside LabelFrames.

I've an array called self.que_lt_verthat contains some names: self.que_lt_ver = ['CARGA', 'MAQUINA', SOLTAR'] . I want to create 3 LabelFrames and each one with a Scrollbar. I've created a Canvas for it, but it only shows the Scroll for the last window:

So how can I modify the code to show a scroll for each LabelFrame?

This is the part of the code where the windows are created:

def createBox(self, window):
    for i in xrange(len(self.que_lt_ver)):
        mybox = LabelFrame(window, padx=5, pady=4)
        mybox.grid(row=i, column=0)
        self.createWindow(mybox, self.que_lt_ver[i], i)

def createWindow(self, box, lt_actual, i):
    self.canvas = Canvas(box, borderwidth=0)
    frame = Frame(self.canvas)
    vsb = Scrollbar(box, orient="vertical", command=self.canvas.yview)
    self.canvas.configure(yscrollcommand=vsb.set, width=1200, heigh=80)       

    vsb.pack(side="right", fill="y")
    self.canvas.pack(side="left", fill="both", expand=True)
    self.canvas.create_window((4,4), window=frame, anchor="nw", tags="frame")

    frame.bind("<Configure>", self.OnFrameConfigure)

    self.fillWindow(lt_actual, frame)

def fillWindow(self, lt_ver, frame):

Thanks in advance.

You create 3 canvas, but all are set in self.canvas.

So self.canvas corresponds to the last one. You configure it 3 times, but never the two firsts.

See my solution (I remove all the object stuff) :

from Tkinter import *

def createBox(window):
    list_ = ['CARGA', 'MAQUINA', 'SOLTAR']
    for i in xrange(3):
        mybox = LabelFrame(window, padx=5, pady=4)
        mybox.grid(row=i, column=0)
        createWindow(mybox, list_[i], i)

def createWindow(box, lt_actual, i):
    canvas = Canvas(box, borderwidth=0)
    frame = Frame(canvas)
    vsb = Scrollbar(box, orient="vertical", command=canvas.yview)
    canvas.configure(yscrollcommand=vsb.set, width=1200, heigh=80)       

    vsb.pack(side="right", fill="y")
    canvas.pack(side="left", fill="both", expand=True)
    canvas.create_window((4,4), window=frame, anchor="nw", tags="frame")

    # be sure that we call OnFrameConfigure on the right canvas
    frame.bind("<Configure>", lambda event, canvas=canvas: OnFrameConfigure(canvas))

    fillWindow(lt_actual, frame)
