在python的tkinter列表框中插入一个按钮？

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listbox中插入一个按钮，就像插入一个刺一样。我如何才能做到这一点？

Answer 1

你不能这样做。从listbox文档中可以看到 "listbox是一个显示字符串列表的小部件"

当然，你可以使用pack、place或grid来在部件中插入一个按钮，但它不会成为listbox数据的一部分--例如，它不会滚动，而且可能会遮住一些数据。

Answer 2

ListBox的一个替代方案是一个可滚动的框架。

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()
