简单的一些实例，能够实现一般的功能就够用了
tkinter：
创建顶层窗口：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
root.mainloop()
label使用：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
label = label(root, text="hello world!")
label.pack()
root.mainloop()
加入一些参数：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
label = label(root, text="hello world!", height=10, width=30, fg="black", bg="pink")
label.pack()
root.mainloop()
frame：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
for relief in [raised, sunken, ridge, groove, solid]:
f = frame(root, borderwidth=2, relief=relief)
label(f, text=relief, width=10).pack(side=left)
f.pack(side=left, padx=5, pady=5)
root.mainloop()
button：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
button(root, text="禁用", state=disabled).pack(side=left)
button(root, text="取消").pack(side=left)
button(root, text="确定").pack(side=left)
button(root, text="退出", command=root.quit).pack(side=right)
root.mainloop()
给按钮加一些参数：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
button(root, text="禁用", state=disabled, height=2, width=10).pack(side=left)
button(root, text="取消", height=2, width=10, fg="red").pack(side=left)
button(root, text="确定", height=2, width=10, fg="blue", activebackground="blue", activeforeground="yellow").pack(
side=left)
button(root, text="退出", command=root.quit, fg="black", height=2, width=10).pack(side=right)
root.mainloop()
entry：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
f1 = frame(root)
label(f1, text="标准输入框：").pack(side=left, padx=5, pady=10)
e1 = stringvar()
entry(f1, width=50, textvariable=e1).pack(side=left)
e1.set("请输入内容")
f1.pack()
f2 = frame(root)
e2 = stringvar()
label(f2, text="禁用输入框：").pack(side=left, padx=5, pady=10)
entry(f2, width=50, textvariable=e2, state=disabled).pack(side=left)
e2.set("不可修改内容")
f2.pack()
root.mainloop()
小案例：摄氏度转为华氏度
# -*- coding: utf-8 -*-
import tkinter as tk
def ctofclicked():
cd = float(entrycd.get())
labelctof.config(text="%.2f摄氏度 = %.2f华氏度" % (cd, cd * 1.8 + 32))
top = tk.tk()
top.title("摄氏度转华氏度")
labelctof = tk.label(top, text="摄氏度转华氏度", height=5, width=30, fg="blue")
labelctof.pack()
entrycd = tk.entry(top, text="0")
entrycd.pack()
btncal = tk.button(top, text="计算", command=ctofclicked)
btncal.pack()
top.mainloop()
radiobutton：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
foo = intvar()
for text, value in [('red', 1), ('greed', 2), ('black', 3), ('blue', 4), ('yellow', 5)]:
r = radiobutton(root, text=text, value=value, variable=foo)
r.pack(anchor=w)
foo.set(2)
root.mainloop()
checkbutton：
# -*- coding: utf-8 -*-
from tkinter import *
root = tk()
root.title("顶层窗口")
l = [('red', 1), ('green', 2), ('black', 3), ('blue', 4), ('yellow', 5)]
for text, value in l:
foo = intvar()
c = checkbutton(root, text=text, variable=foo)
c.pack(anchor=w)
root.mainloop()
其他的东西比如文本框，滚动条
其实类似，这里就不全部列出来了，其实最常用的也是上面的这些东西
下面做一些小案例：
# -*- coding:utf-8 -*-
from tkinter import *
class mainwindow:
def __init__(self):
self.frame = tk()
self.label_name = label(self.frame, text="name:")
self.label_age = label(self.frame, text="age:")
self.label_sex = label(self.frame, text="sex:")
self.text_name = text(self.frame, height=1, width=30)
self.text_age = text(self.frame, height=1, width=30)
self.text_sex = text(self.frame, height=1, width=30)
self.label_name.grid(row=0, column=0)
self.label_age.grid(row=1, column=0)
self.label_sex.grid(row=2, column=0)
self.button_ok = button(self.frame, text="ok", width=10)
self.button_cancel = button(self.frame, text="cancel", width=10)
self.text_name.grid(row=0, column=1)
self.text_age.grid(row=1, column=1)
self.text_sex.grid(row=2, column=1)
self.button_ok.grid(row=3, column=0)
self.button_cancel.grid(row=3, column=1)
self.frame.mainloop()
frame = mainwindow()
最后一个综合案例
计算器：
# -*- coding:utf-8 -*-
from tkinter import *
def frame(root, side):
w = frame(root)
w.pack(side=side, expand=yes, fill=both)
return w
def button(root, side, text, command=none):
w = button(root, text=text, command=command)
w.pack(side=side, expand=yes, fill=both)
return w
class calculator(frame):
def __init__(self):
frame.__init__(self)
self.option_add('*font', 'verdana 12 bold')
self.pack(expand=yes, fill=both)
self.master.title('simple cal')
self.master.iconname('calc1')
display = stringvar()
entry(self, relief=sunken, textvariable=display).pack(side=top, expand=yes, fill=both)
for key in ('123', '456', '789', '+0.'):
keyf = frame(self, top)
for char in key:
button(keyf, left, char, lambda w=display, c=char: w.set(w.get() + c))
opsf = frame(self, top)
for char in '-*/=':
if char == '=':
btn = button(opsf, left, char)
btn.bind('<buttonrelease-1>', lambda e, s=self, w=display: s.calc(w), '+')
else:
btn = button(opsf, left, char, lambda w=display, s='%s' % char: w.set(w.get() + s))
clearf = frame(self, bottom)
button(clearf, left, 'clear', lambda w=display: w.set(''))
def calc(self, display):
try:
display.set(eval(display.get()))
except:
display.set('error')
if __name__ == '__main__':
calculator().mainloop()
