因此，我编写了一个代码，该代码生成一个窗口，窗口上方有一个按钮，下方有一个小框。您单击顶部的按钮，然后在下面的小框中的col 0行0中创建另一个按钮，再次单击它，然后在col 0行1中创建另一个按钮，到目前为止一切正常。
我现在要做的是添加一个滚动条，这样，如果在下面小框中显示的行全部被按钮填充，我可以向下滚动到添加的按钮。因此，通常的问题是：如何将滚动条添加到通过grid（）进行组织的包含创建的按钮的框架中？
我已经尝试将创建的按钮网格化到一个框架中，并将该框架设置到画布中，然后将滚动条添加到该画布上，但是没有任何效果。 （在下面的代码中，取出滚动条小部件的四行，您将看到程序的工作原理。添加四行奇怪地使其他任何内容消失。）

第15行的更正：
def update_scrollregion(event):
Canv.configure(scrollregion=Canv.bbox("all"))
Globalframe = Frame(window, height = 210, width = 725)
Globalframe.place(relx = 0.03, rely = 0.54475)
Canv = Canvas(Globalframe, height = 198, width = 712)
Canv.grid(row=0,column=0,sticky="nsew")
field = Frame(Canv)
Canv.create_window(0,0,window=field,anchor="nw")
## add a scrollbar & configure it ##
s = Scrollbar(Globalframe, orient=VERTICAL)
s.config(command=Canv.yview)
Canv.config(yscrollcommand=s.set)
s.grid(row=0, column=1, sticky="ns")
field.bind("<Configure>",update_scrollregion)
多亏了j_4321（Tkinter canvas & scrollbar with grid）这个家伙，我才找到了这个选项！
