在Python的tkinter列表框中插入按钮？

Question

...
self.myListbox=tkinter.Listbox() 
self.myListbox.pack()
self.myButton=tkinter.Button(self.myListbox,text="Press")

self.myListbox.insert(1,myButton.pack())
...

我想在列表框里插入一个按钮，就像插入一个字符串一样。我该怎么做呢？

一个可以替代列表框的选择是可滚动的框架；

import functools
try:
    from tkinter import *

    import tkinter as tk
except ImportError: 
    from Tkinter import *
    import Tkinter as tk#

window = Tk()
frame_container=Frame(window)

canvas_container=Canvas(frame_container, height=100)
frame2=Frame(canvas_container)
myscrollbar=Scrollbar(frame_container,orient="vertical",command=canvas_container.yview) # will be visible if the frame2 is to to big for the canvas
canvas_container.create_window((0,0),window=frame2,anchor='nw')

def func(name):
    print (name)
mylist = ['item1','item2','item3','item4','item5','item6','item7','item8','item9']
for item in mylist:
    button = Button(frame2,text=item,command=functools.partial(func,item))
    button.pack()


frame2.update() # update frame2 height so it's no longer 0 ( height is 0 when it has just been created )
canvas_container.configure(yscrollcommand=myscrollbar.set, scrollregion="0 0 0 %s" % frame2.winfo_height()) # the scrollregion mustbe the size of the frame inside it,
                                                                                                            #in this case "x=0 y=0 width=0 height=frame2height"
                                                                                                            #width 0 because we only scroll verticaly so don't mind about the width.

canvas_container.pack(side=LEFT)
myscrollbar.pack(side=RIGHT, fill = Y)

frame_container.pack()
window.mainloop()

你不能这样做。根据列表框的说明：“列表框是一个显示字符串列表的控件”。

当然，你可以使用pack、place或grid这些方法把按钮放在这个控件里面，但这样按钮就不算是列表框的数据了——比如它不会跟着一起滚动，可能还会遮住一些数据。
