用TKINTER框架（Ubuntu）将鼠标车轮绑定

Question

滚动运转良好。但是，如何将鼠标轮与滚动绑定？我正在使用Ubuntu。

＃代码。

from tkinter import *
from tkinter import ttk
win = Tk()

wrapper1 = LabelFrame(win)
mycanvas = Canvas(wrapper1).pack(side=LEFT, fill='both', expand='yes')
yscrollbar = ttk.Scrollbar(wrapper1, orient="vertical", command=mycanvas.yview ).pack(side=RIGHT, fill='y')
mycanvas.configure(yscrollcommand=yscrollbar.set)
mycanvas.bind('<Configure>', lambda e: mycanvas.configure(scrollregion = mycanvas.bbox('all')))
myframe = Frame(mycanvas)
mycanvas.create_window((0,0), window=myframe, anchor='nw')

wrapper1.pack(fill="both", expand="yes", padx=10, pady=10)

for i in range(30):
    Button(myframe, text="btn" + str(i)).pack()

win.geometry("500x500")
win.resizable(height=FALSE,width=FALSE)


win.mainloop()
