在Button的command绑定中，如果给的一个函数，则表示执行一次。

import tkinter as Tkfrom tkinter import messageboxi = 0def myLabel():global root,is = Tk.Label(root,text="the import thing is :" )s.pack()root = Tk.Tk()def fun1():if messagebox.showwarning("hello","你确定要离开吗？"):root.destroy()def fun2():if messagebox.showwarning("hello","just is hello"):root.destroy()w1 = Tk.Label(root,text="欢迎来到我的世界")
w2 = Tk.Label(root,text="好好学习，天天向上",background="white")
w3 = Tk.Label(root,text="轻松愉快，就选python！",background="red")w1.pack()
w2.pack()
w3.pack()b = Tk.Button(root,text="Python",command = myLabel())
b.pack()root.protocol('WM_DELETE_WINDOW',fun1)
root.mainloop()

此时表示执行myLabel()函数一次，在点击Button时不在进行调用，正确的写法是去掉括号

Button绑定的两种方法：

1、第一种是方法绑定事件

b = Tk.Button(root,text="Python",command = myLabel) b.pack()

2、第二种方法绑定事件

b = Tk.Button(py, text = "Python") # command = myLabel ⽊有了

b.bind("<Button-1>", myLabel) # 多了这⼀句

 

使用grid布局：

import tkinter as Tkfrom tkinter import messageboxroot = Tk.Tk()Tk.Label(root,text="account:").grid(row=0,sticky="w")
Tk.Entry(root).grid(row=0,column=1,sticky="e")Tk.Label(root,text="password:").grid(row=1,sticky="w")
Tk.Entry(root).grid(row = 1,column = 1,sticky="e")root.mainloop()

 使用Lable标签模拟Button标签

import tkinter as Tkfrom tkinter import messageboxdef myLabel(event):global roots = Tk.Label(root,text="好好学习，天天向上")s.pack()root = Tk.Tk()n = Tk.Label(root,text="button")
n.bind("<Button-1>",myLabel)
n.pack()root.mainloop()

简单的登录系统：

import tkinter as Tkfrom tkinter import messageboxdef reg():accout_get1 = accout_get.get()password_get1 = password_get.get()if accout_get1 == "liyong" and password_get1 == "102520":msg_label["text"] = "load succecced!"else:msg_label["text"] = "load fail!"root = Tk.Tk()s = Tk.Label(root,text="ok")accout_label = Tk.Label(root,text="accout:")
accout_label.grid(row=0,sticky="w")
accout_get = Tk.Entry(root)
accout_get.grid(row=0,column=1,sticky="e")password_label = Tk.Label(root,text="password:")
password_label.grid(row=1,column=0,sticky="w")password_get = Tk.Entry(root)
password_get.grid(row=1,column=1,sticky="e")button_load = Tk.Button(root,text="load",command=reg)
#button_load.bind("Button-1",reg)
button_load.grid(row=2,column=1,sticky="e")msg_label = Tk.Label(root,text=" ")
msg_label.grid(row=3)root.mainloop()

其中msg_label的文件应该是通过什么方式进行了重写，

msg_label["text"] = "load succecced!"

这里的Label属性实现了动态的展示

菜单的简单添加：

import tkinter as Tkfrom tkinter import messageboxroot = Tk.Tk()menuBar = Tk.Menu(root)for item in ["文件","编辑","视图","关于"]:menuBar.add_command(label = item)root["menu"] = menuBarroot.mainloop()

这⾥要注意的是我们可以先把⼦菜单做好，然后再做上层菜单。

import tkinter as Tkfrom tkinter import messageboxroot = Tk.Tk()menuBar = Tk.Menu(root)fMenu = Tk.Menu(menuBar)
for item in ["新建","打开","保存","另存为","退出"]:fMenu.add_command(label = item)eMenu = Tk.Menu(menuBar)
for item in ["复制","粘贴","剪切","撤销"]:eMenu.add_command(label = item)vMenu = Tk.Menu(menuBar)
for item in ["默认视图","全屏模式","显示/隐藏菜单"]:vMenu.add_command(label = item)aMenu = Tk.Menu(menuBar)
for item in ["版权信息","帮助文档"]:aMenu.add_command(label = item)menuBar.add_cascade(label = "文件", menu = fMenu)
menuBar.add_cascade(label = "编辑", menu = eMenu)
menuBar.add_cascade(label = "视图", menu = vMenu)
menuBar.add_cascade(label = "关于", menu = aMenu)root["menu"] = menuBarroot.mainloop()

弹出菜单的制作：

import tkinter as Tkfrom tkinter import messageboxdef myLabel():global rootTk.Label(root,text="python !!!").pack()root = Tk.Tk()menuBar = Tk.Menu(root)for item in ["C/C++","JavaEE","Android","PHP","UI","IOS","JS","could"]:menuBar.add_command(label = item)menuBar.add_command(label = "python",command = myLabel)def pop(event):menuBar.post(event.x_root,event.y_root)root.bind("<Button-3>",pop)root.mainloop()

radiobutton:

import tkinter as Tkfrom tkinter import messageboxroot = Tk.Tk()menuBar = Tk.Menu(root)
sonBar = Tk.Menu(menuBar)item = ["语文","数学","英语","逻辑","科学","心理","体育"]for echa in item:sonBar.add_radiobutton(label = echa)menuBar.add_cascade(label = "课程",menu = sonBar)root["menu"] = menuBarroot.mainloop()

checkbutton

import tkinter as Tkfrom tkinter import messageboxroot = Tk.Tk()menuBar = Tk.Menu(root)
sonBar = Tk.Menu(menuBar)items = ["语文","数学","英语"]for item in items:sonBar.add_checkbutton(label = item)menuBar.add_cascade(label = "file",menu = sonBar)root["menu"] = menuBarroot.mainloop()

总结： tkinter.messagebox的几种方法

showinfo
showwarning
showerror
askquestion
askyesno
askokcancel
askretrycancel
 

checkButton使用

import tkinter as Tkfrom tkinter import messageboxdef fun1():global lablab["text"] = "python 1 check"root = Tk.Tk()button1 = Tk.Checkbutton(root,text="python1",command = fun1)
#root.bind()
button1.pack()lab = Tk.Label(root,text=" ")
lab.pack()root.mainloop()

text文本使用

import tkinter as Tkfrom tkinter import messageboxroot =Tk.Tk()text = Tk.Text(root,height=30,widt=30)
text.pack()root.mainloop()

Canvas

Toplevel

import tkinter as Tkfrom tkinter import messageboxroot =Tk.Tk()lb1 = Tk.Label(root,text="root label")
lb1.pack()la2 = Tk.Toplevel(root,width=30,height=40)
#la2.pack()root.mainloop()

button:

画象棋：

from tkinter import *
root = Tk()
root.title("中国象棋棋盘⼿绘")
canv = Canvas(root, width = 400, height = 450)
canv.create_line((0,2), (400,2), width = 2)
for i in range(10):canv.create_line((0, i * 50), (400, i * 50), width = 2)canv.create_line((3,0), (3,450), width = 2)for i in range(8):canv.create_line((i * 50,0), (i * 50,200), width = 2)for i in range(8):canv.create_line((i * 50,250), (i * 50,450), width = 2)canv.create_line((397,0), (397,450), width = 2)canv.create_line((150,0), (250,100), width = 2)canv.create_line((150,100), (250,0), width = 2)canv.create_line((150,450), (250,350), width = 2)canv.create_line((150,350), (250,450), width = 2)canv.create_text(110, 220, text = "汉界")canv.create_text(290, 220, text = "楚河")canv.pack()root.mainloop()
