python tkinterでスクロールを実装した際に、スクロールバーにフレームが被さらない事、且つ、フレームが途切れるのを予防したい

Question

### FrameClass
class ClassFrame(tk.Frame):
    def __init__(self , master , bg = None , width = None , height = None):
        super().__init__(master , bg = bg , width = width , height = height)

### LeftFrameClass
class ClassLabelFrameLeft(tk.LabelFrame):
    def __init__(self , master , text = None , pad_x = None , pad_y = None , bg = None):
        super().__init__(master , text = text , padx = pad_x , pady = pad_y , bg = bg)

### CanvasClass
class ClassCanvas(tk.Canvas):
    def __init__(self , master , scroll_width , scroll_height , bg):
        super().__init__(master , bg = bg)
        bar_y = tk.Scrollbar(self , orient = tk.VERTICAL)
        bar_x = tk.Scrollbar(self , orient = tk.HORIZONTAL)
        #self.bind_all("<MouseWheel>" , lambda eve:self.yview_scroll(int(-eve.delta/120) , 'units'))
        bar_y.pack(side = tk.RIGHT , fill = tk.Y)
        bar_x.pack(side = tk.BOTTOM , fill = tk.X)
        bar_y.config(command = self.yview)
        bar_x.config(command = self.xview)
        self.config(yscrollcommand=bar_y.set , xscrollcommand=bar_x.set)
        self.config(scrollregion=(0 , 0 , scroll_width , scroll_height))
        self.xview_moveto(0)
        self.yview_moveto(0)

class Model():
    def __init__(self):
        self.width = 1000
        self.height = 600
        self.leftManu_scroll_max = ({"width": 110, "height": self.height + 300})

    def __init__(self, master, model):
        self.master = master
        self.model = model
        
        ### LeftMenu_Frame 
        leftFrame = ClassFrame(self.master, bg="snow", width=self.model.leftManu_scroll_max["width"] + 20)
        leftFrame.pack(side=tk.LEFT, expand=False, fill=tk.Y)
        ### canvas 
        self.left_canvas = ClassCanvas(leftFrame, scroll_width=self.model.leftManu_scroll_max["width"], scroll_height=self.model.leftManu_scroll_max["height"], bg="green")
        self.left_canvas.place(x=0 , y=0 , relheight=1 , relwidth=1)
        ### canvasFrame
        self.canvasLeftFrame = tk.Frame(self.left_canvas)
        self.left_canvas_conf = self.left_canvas.create_window((0,0), window=self.canvasLeftFrame, anchor=tk.NW, width=self.model.leftManu_scroll_max["width"], height=self.model.leftManu_scroll_max["height"])
        ### LeftManu_Item
        self.label_frame_left_menu = ClassLabelFrameLeft(self.canvasLeftFrame , text="MENU", pad_y=7 , bg='snow')
        self.label_frame_left_menu.place(x=0, y=0, width=self.model.leftManu_scroll_max["width"])
        leftBottons = ['sample1','sample2','sample3','sample4','sample5','sample6','sample7','sample8','sample9','sample10',
                        'sample11','sample12','sample13','sample14','sample15','sample16','sample17','sample18','sample19','sample20','sample21','sample22','sample23',]
        ### LeftFrameButton
        for text in leftBottons:
            left_button = tk.Button(self.label_frame_left_menu, text = text, command='')
            left_button.pack(anchor=tk.NW, fill=tk.X, padx=(10 , 10), pady=(0 , 10))

class Controller():
    def __init__(self, master, model, view):
        self.master = master
        self.model = model
        self.view = view
        def left_canvas_resize(event):
            self.view.left_canvas.itemconfigure(self.view.left_canvas_conf, width=event.width-19.5, height=event.height-19.5)
        self.view.left_canvas.bind("<Configure>", left_canvas_resize)

class Application(tk.Frame):
	def __init__(self, master):
		super().__init__(master)
		self.pack()
		self.model = Model()

フレームが途切れるのを予防したい

def left_canvas_resize(event):
    self.view.left_canvas.itemconfigure(self.view.left_canvas_conf, width=event.width-19.5, height=event.height-19.5)
self.view.left_canvas.bind("<Configure>", left_canvas_resize)

リサイズ・イベント内のリサイズで途切れてるようです。
このイベントはウィンドウ移動やリサイズしなくても初期化時に一度呼ばれます
スクロールさせたい場合は、このリサイズ・イベントは不要です。
