1.创建从一个列表框选择内容添加到另一个列表框

from tkinter import *

root = Tk()

def callbutton1():

    for i in listb.curselection():

        listb2.insert(0,listb.get(i))

def callbutton2():

    for i in listb2.curselection():

        listb2.delete(i)

li = ['c','python','php','html','SQL','java']

listb = Listbox(root)

listb2 = Listbox(root)

for item in li:

    listb.insert(0,item)

listb.grid(row = 0,column = 0,rowspan = 2)

b1 = Button(root,text = '添加>>',command = callbutton1,width = 20)

b2 = Button(root,text = '删除<<',command = callbutton2,width = 20)

b1.grid(row = 0,column = 1,rowspan = 2)

b2.grid(row = 1,column = 1,rowspan = 2)

listb2.grid(row = 0,column = 2,rowspan = 2)

root.mainloop()

结果如下：

2.演示各消息框的程序

import tkinter as tk

from tkinter import messagebox as msgbox

def btn1_clicked():

    msgbox.showinfo("Info","Showinfo test.")

def btn2_clicked():

    msgbox.showinfo("Warning","Showwarning test.")

def btn3_clicked():

    msgbox.showinfo("Error","Showerror test.")

def btn4_clicked():

    msgbox.showinfo("Question","Askquestion test.")

def btn5_clicked():

    msgbox.showinfo("OKCancel","Askookcancel test.")

def btn6_clicked():

    msgbox.showinfo("YesNo","Askyesno test.")

def btn7_clicked():

    msgbox.showinfo("Retry","Askretrycancel test.")

root = tk.Tk()

root.title("MsgBox Test")

btn1 = tk.Button(root,text = "showinfo",command = btn1_clicked)

btn1.pack(fill = tk.X)                              #X为大写

btn2 = tk.Button(root,text = "showwarning",command = btn2_clicked)

btn2.pack(fill = tk.X)

btn3 = tk.Button(root,text = "showerror",command = btn3_clicked)

btn3.pack(fill = tk.X)

btn4 = tk.Button(root,text = "askquestion",command = btn4_clicked)

btn4.pack(fill = tk.X)

btn5 = tk.Button(root,text = "askokcancel",command = btn5_clicked)

btn5.pack(fill = tk.X)

btn6 = tk.Button(root,text = "askyesno",command = btn6_clicked)

btn6.pack(fill = tk.X)

btn7 = tk.Button(root,text = "askretrycancel",command = btn7_clicked)

btn7.pack(fill = tk.X)

root.mainloop()

结果如下：（效果不太好）
