# 网上搜来的用例 #

from tkinter import *
    
    def data():
        for i in range(50):
           Label(frame,text=i).grid(row=i,column=0)
           Label(frame,text="my text"+str(i)).grid(row=i,column=1)
           Label(frame,text="..........").grid(row=i,column=2)
    
    # 少了这个就滚动不了
    def myfunction(event):
        canvas.configure(scrollregion=canvas.bbox("all"),width=200,height=200)
    
    root=Tk()
    sizex = 800
    sizey = 600
    posx  = 100
    posy  = 100
    root.wm_geometry("%dx%d+%d+%d" % (sizex, sizey, posx, posy))
    
    myframe=Frame(root,relief=GROOVE,width=50,height=100,bd=1)
    myframe.place(x=10,y=10)
    
    canvas=Canvas(myframe)
    frame=Frame(canvas)
    myscrollbar=Scrollbar(myframe,orient="vertical",command=canvas.yview)
    canvas.configure(yscrollcommand=myscrollbar.set)
    
    myscrollbar.pack(side="right",fill="y")
    canvas.pack(side="left")
    canvas.create_window((0,0),window=frame,anchor='nw')
    frame.bind("<Configure>",myfunction)
    data()
    root.mainloop()

# 实际演练 #

def refresh_scroll(self, event):
            self.canvas.configure(scrollregion=self.canvas.bbox("all"),width=600,height=600)
    
        def __init_gui(self):
            self.__lb_frame = tk.Frame(self)
            self.__init_mod_listbox(self.__lb_frame)
            self.__lb_frame.pack(side=tk.LEFT, expand=0)
    
            _f = tk.Frame(self, width=600, height=600)
            _f.pack(side=tk.LEFT, expand=0)
            _f.pack_propagate(0)
    
            canvas=tk.Canvas(_f, width=600,height=600)
            __options_f = tk.Frame(canvas)
            __options_f.pack(side=tk.LEFT, fill=tk.BOTH, expand=1)
            
            __options_f.bind("<Configure>",self.refresh_scroll)
            
    
            hbar=tk.Scrollbar(_f, orient=tk.HORIZONTAL)
            hbar.pack(side=tk.BOTTOM, fill=tk.X, expand=0)
            hbar.config(command=canvas.xview)
            vbar=tk.Scrollbar(_f, orient=tk.VERTICAL)
            vbar.pack(side=tk.RIGHT, fill=tk.Y)
            vbar.config(command=canvas.yview)
            
            canvas.config(xscrollcommand=hbar.set, yscrollcommand=vbar.set)
            
            canvas.pack(side=tk.LEFT, expand=False, fill=tk.BOTH)
            canvas.create_window((400,1600),window=__options_f,anchor='nw')
            self.canvas = canvas

少了这行无效：

def refresh_scroll(self, event):
            self.canvas.configure(scrollregion=self.canvas.bbox("all"),width=600,height=600)
