Question

我有一个非常基本的问题，即通过使用Python Tkinter窗口我想显示列表框，从该列表中，我想显示一些我选择的信息。但是我收到了一些错误。

import Tkinter
from Tkinter import*
import tkMessageBox
window = Tk()
window.title('ex - 4,listing option')
frame = Frame(window)
listbox = Listbox(frame)
listbox.insert(1, 'Manual')
listbox.insert(2, 'Auto')
listbox.insert(3, 'AI')
def dialog():
    tkMessageBox('selection','your chice:' + \
    listbox.get(listbox.curselection()))
btn = Button(frame, text = 'Choose',command = dialog)
btn.pack(side = RIGHT, padx = 5)
listbox.pack(side = LEFT)
frame.pack(padx = 30, pady = 30)
window.mainloop()

错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1410, in __call__
    return self.func(*args)
  File "C:\Users\Subhro Jyoti\Desktop\python\ex - 4,listing option", line 12, in dialog
    tkMessageBox('selection','your chice:' + listbox.get(listbox.curselection()))
TypeError: 'module' object is not callable

Answer 1

tkMessageBox是不同类型的消息框的集合，您必须指明要使用的消息框。例如：

def dialog():
    tkMessageBox.showinfo('selection','your chice:' + 
    listbox.get(listbox.curselection()))

您的选择是showinfo，showwarning，showerror，askquestion，askokcancel，askyesno或askretrycancel

Python Tkinter列表选项未显示信息
