接着上篇tkinter的学习记录
1、tkinter之单选和多选
#coding:utf-8 from tkinter import * # 定义一个root主窗口 root = Tk() root.title("应用程序窗口") # 定义两个变量，用于判断复选框状态 box_1 = False box_2 = False # 列表，用于存放选中内容 List_Content = [] def click_c1(): global box_1 # 复选框被选中，box_1置为True box_1 = not box_1 if box_1: List_Content.append('Windows') l['text'] = List_Content else: List_Content.remove('Windows') l['text'] = List_Content def click_c2(): global box_2 box_2 = not box_2 if box_2: List_Content.append('Linux') l['text'] = List_Content else: List_Content.remove('Linux') l['text'] = List_Content # 定义两个复选框，并绑定相关事件 ck1 = Checkbutton(root, text='Windows', command=click_c1) ck1.grid(row=0, column=1) ck2 = Checkbutton(root, text='Linux', command=click_c2) ck2.grid(row=1, column=1) l_com = Label(root, text='已选中：') l_com.grid(row=2, column=0) l = Label(root, text='') l.grid(row=2, column=1) root.mainloop()
2、tkinter之LabelFrame布局
#coding:utf-8 import tkinter as tk #标签框架 root = tk.Tk() root.title("应用程序窗口") #新建标签框架 group = tk.LabelFrame(root,text="最好的语言是?") group.pack(padx=10,pady=10) LANGS = [("python",1),("C",2),("Java",3),("Lua",4)] v = tk.IntVar() for lang,num in LANGS: #选中后 把num的值赋给 variable b = tk.Radiobutton(group,text=lang,variable = v ,value =num) b.pack(anchor = tk.W) l = tk.Label(root,textvariable=v)#显示标签 l.pack(side=tk.LEFT) tk.mainloop()
3、tkinter实现登录窗口
#coding:utf-8 from tkinter import * import tkinter as tk root = Tk() root.title('登录窗口') # 按扭调用的函数， def reg(): User = e1.get() Pwd = e2.get() len_user = len(User) len_pwd = len(Pwd) if User == '111' and Pwd == '222': l_msg['text'] = '登陆成功' else: l_msg['text'] = '用户名或密码错误' e1.delete(0, len_user) e2.delete(0, len_pwd) tk.Label(root, text="账号：").grid(row=0, column=0) # 位于第0行，第0列 tk.Label(root, text="密码：").grid(row=1, column=0) # 位于第1行，第0列 v1 = tk.StringVar() v2 = tk.StringVar() e1 = tk.Entry(root, textvariable=v1) e2 = tk.Entry(root, textvariable=v2, show="*") # show：以*显示 e1.grid(row=0, column=1, padx=10, pady=5) # 位于第0行，第1列 e2.grid(row=1, column=1, padx=10, pady=5) # 位于第1行，第1列 # 第三行登陆按扭，command绑定事件 b_login = Button(root, text='登陆', command=reg) b_login.grid(row=2, column=1, sticky=E) tk.Button(root,text="退出", command=root.quit) .grid(row=2,column=2,sticky = tk.E) def show(): print("账号:%s" %e1.get()) print("密码:%s" %e2.get()) tk.Button(root,text="获取信息",width=10,command=show) .grid(row=2,column=0,sticky = tk.W) # 登陆是否成功提示 l_msg = Label(root, text='') l_msg.grid(row=3) root.mainloop()
4、tkinter实现计算器功能
#coding:utf-8 import tkinter as tk root = tk.Tk() root.title('简易计算器') v1 = tk.StringVar() v2 = tk.StringVar() v3 = tk.StringVar() def test(content): return content.isdigit() # 数字会返回true 非数字返回false testCMD = root.register(test) # validate触发方法是关键字触发 e1 = tk.Entry(root, width=10, textvariable=v1, validate='key', validatecommand=(testCMD, "%P")).grid(row=0, column=0) tk.Label(root, text="+").grid(row=0, column=1) # 存放+号的 e2 = tk.Entry(root, width=10, textvariable=v2, validate='key', validatecommand=(testCMD, "%P")).grid(row=0, column=2) tk.Label(root, text="=").grid(row=0, column=3) # 存放=号的 e3 = tk.Entry(root, textvariable=v3, state="readonly").grid(row=0, column=4) # 只能读取 def calc(): result = int(v1.get()) + int(v2.get()) v3.set(str(result)) tk.Button(root, text="计算结果", command=calc).grid(row=1, column=2) tk.mainloop()
