Autohide Tkinter холст полоса прокрутки с геометрией упаковки

Question

Мне нужна помощь с authiding прокруткой полосы tkinter, когда она не нужна. Я нашел из effbot.org этот код, который автоматически скрывает полосу прокрутки, но только с геометрией сетки. Я не использую геометрию сетки в моем случае. Вот мой код.

import Tkinter as tk 
from Tkinter import * 
import tkFont 


class AutoScrollbar(Scrollbar): 
    # a scrollbar that hides itself if it's not needed. only 
    # works if you use the grid geometry manager. 
    def set(self, lo, hi): 
     if float(lo) <= 0.0 and float(hi) >= 1.0: 
      # grid_remove is currently missing from Tkinter! 
      self.tk.call("grid", "remove", self) 
     else: 
      self.grid() 
     Scrollbar.set(self, lo, hi) 
    def pack(self, **kw): 
     raise TclError, "cannot use pack with this widget" 
    def place(self, **kw): 
     raise TclError, "cannot use place with this widget" 


class MainWindow(tk.Tk): 

    def __init__(self, *args, **kwargs): 
     tk.Tk.__init__(self, *args, **kwargs) 
     w = 1200 
     h = 650 
     x = self.winfo_screenwidth()/2 - w/2 
     y = self.winfo_screenheight()/2 - h/2 
     self.geometry("%ix%i+%i+%i" % (w, h, x, y)) 

     self.mainTopFrame = Frame(self, height=75) 
     self.mainTopFrame.pack(side=TOP, fill=X)

     self.canvas.pack(side=TOP, fill=BOTH, expand=1) 
     self.yscroll.pack(side=RIGHT, fill=Y) 
     self.canvas.create_window((4,4), window=self.mainBottomFrame, anchor=NW) 
     self.mainBottomFrame.bind("<Configure>", self.onFrameConfigure) 
     self.menuFrame = Frame(self.mainTopFrame, bg='#545454') 
     self.menuFrame.pack(side=TOP, fill=BOTH, expand=True) 

     self.container = Frame(self.mainBottomFrame) 
     self.container.pack(side=TOP, fill=BOTH, expand=True) 
     self.frames = {} 
     for F in (MonitorPage, PlanPage, DataLogPage, HelpPage): 
      self.frame = F(self.container, self) 
      self.frames[F] = self.frame 
      self.frame.grid(row=0, column=0, sticky="nsew") 
     self.show_frame(MonitorPage) 

    def show_frame(self, cont): 
     self.frame = self.frames[cont] 
     self.frame.tkraise() 

    def onFrameConfigure(self, event): 
     '''Reset the scroll region to encompass the inner frame''' 
     self.canvas.configure(scrollregion=self.canvas.bbox("all")) 

class AutoScrollbar(Scrollbar): 
    # a scrollbar that hides itself if it's not needed. only 
    # works if you use the grid geometry manager. 
    def set(self, lo, hi): 
     if float(lo) <= 0.0 and float(hi) >= 1.0:

     self.leftFrame0 = Frame(self, bg='#888888') 
     self.leftFrame0.pack(side=LEFT, fill=BOTH)

     self.label2.pack() 


class PlanPage(tk.Frame, MainWindow): 
    def __init__(self, parent, controller): 
     tk.Frame.__init__(self, parent) 

class DataLogPage(tk.Frame): 
    def __init__(self, parent, controller): 
     tk.Frame.__init__(self, parent) 

class HelpPage(tk.Frame): 
    def __init__(self, parent, controller): 
     tk.Frame.__init__(self, parent) 


if __name__ == '__main__': 
    rungui = MainWindow() 
    rungui.mainloop() 

Поэтому я хочу скрытие скроллбара даже когда я использую пакет geometry.I надеется, что я сделал мой вопрос ясен. Я очень новичок в python и tkinter.

Я приспособил пример из effbot.org упаковать метод:

from Tkinter import * 

class AutoScrollbar(Scrollbar): 
    # a scrollbar that hides itself if it's not needed. only 
    # works if you use the grid geometry manager. 
    def set(self, lo, hi): 
     if float(lo) <= 0.0 and float(hi) >= 1.0: 
      # grid_remove is currently missing from Tkinter! 
      self.pack_forget() 
     else: 
      if self.cget("orient") == HORIZONTAL: 
       self.pack(fill=X) 
      else: 
       self.pack(fill=Y) 
     Scrollbar.set(self, lo, hi) 
    def grid(self, **kw): 
     raise TclError, "cannot use grid with this widget" 
    def place(self, **kw): 
     raise TclError, "cannot use place with this widget" 

# create scrolled canvas 

root = Tk() 

hscrollbar = AutoScrollbar(root, orient=HORIZONTAL) 
canvas = Canvas(root, 
       xscrollcommand=hscrollbar.set) 
canvas.pack(side=TOP, fill=BOTH, expand=True) 
hscrollbar.pack() 

hscrollbar.config(command=canvas.xview) 

# make the canvas expandable 
root.grid_rowconfigure(0, weight=1) 
root.grid_columnconfigure(0, weight=1) 

# create canvas contents 

frame = Frame(canvas) 
frame.rowconfigure(1, weight=1) 
frame.columnconfigure(1, weight=1) 

rows = 5 
for i in range(1,rows): 
    for j in range(1,10): 
     button = Button(frame, padx=7, pady=7, text="[%d,%d]" % (i,j)) 
     button.grid(row=i, column=j, sticky='news') 

canvas.create_window(0, 0, anchor=NW, window=frame) 

frame.update_idletasks() 

canvas.config(scrollregion=canvas.bbox("all")) 

root.mainloop()
