button按钮的生成：
import Tkinter as tk window=tk.Tk() def buttonClick(): print "Beep!" button=tk.Button(window,text="Click me!",command=buttonClick) button.pack() window.mainloop()
同理将方法改为改变按钮上的文字
import Tkinter as tk window=tk.Tk() def buttonClick(): # print "Beep!" button.config(text="Clicked!") button=tk.Button(window,text="Click me!",command=buttonClick) button.pack() window.mainloop()
点击按钮的计数
import Tkinter as tk window=tk.Tk() count=0 def buttonCount(): global count count+=1 button.config(text=str(count)) button=tk.Button(window,text="count",command=buttonCount) button.pack() window.mainloop()
创建文本框，里面有一个按钮和文本框，通过获取文本框的内容，每点击一次按钮，都复制文本框中的内容并一起显示在文本框中。
import Tkinter as tk window=tk.Tk() def changeStr(): stringCopy=entry.get() entry.insert(0,stringCopy) entry=tk.Entry(window) button=tk.Button(window,text="StrChange",command=changeStr) entry.pack() button.pack() window.mainloop()
其中，entry.insert中参数第一个为插入的位置。
将文本框中的内容反面显示于文本框中
import Tkinter as tk window=tk.Tk() def changeStr(): stringCopy=entry.get() stringCopy=stringCopy[::-1] entry.delete(0,tk.END) entry.insert(0,stringCopy) entry=tk.Entry(window) button=tk.Button(window,text="StrChange",command=changeStr) entry.pack() button.pack() window.mainloop()
添加密码框，用于输入密码的文本框常常在输入密码时不会显示密码，而是在每个字符的位置显示星号（*),使用方式：在添加文本框时，添加一个额外的具名自变量，这样文本框就变成了一个密码框
在GUI中会有一个输入密码的框和一个提交密码的按钮。如果密码正确，底部会出现一个写有Correct的标签，负责它会写Incorrect。
import Tkinter as tk window=tk.Tk() def checkPassword(): password="Apple" enterPass=passwordEntry.get() if enterPass == password: confirmLabel.config(text="Correct") else: confirmLabel.config(text="Incorrect") passwordLabel=tk.Label(window,text="Password") passwordEntry=tk.Entry(window,show="*") button=tk.Button(window,text="Enter",command=checkPassword) confirmLabel=tk.Label(window) passwordLabel.pack() passwordEntry.pack() button.pack() confirmLabel.pack() window.mainloop()
构造句子生成器：列表与随机函数的配合使用
import Tkinter as tk import random window=tk.Tk() def randomNoun(): nouns=["cats","hippos","cakes"] noun=random.choice(nouns) return noun def randomVerb(): verbs=["eats","likes","hates","has"] verb=random.choice(verbs) return verb def buttonClick(): name=nameEntry.get() verb=randomVerb() noun=randomNoun() sentence=name+" "+verb+" "+noun result.delete(0,tk.END) result.insert(0,sentence) nameLabel=tk.Label(window,text="Name:") nameEntry=tk.Entry(window) button=tk.Button(window,text="Generate",command=buttonClick) result=tk.Entry(window) nameLabel.pack() nameEntry.pack() button.pack() result.pack() window.mainloop()
猜数字游戏：生成一个1-10之间的随机数，看是否成功猜测，并计算游戏的胜利次数（标签显示）
import random import Tkinter as tk window=tk.Tk() maxNo=10 score=0 rounds=0 def buttonClick(): global score global rounds try: guess=int(guessBox.get()) if 0<guess<=maxNo: result=random.randrange(1,maxNo+1) if guess==result: score=score+1 rounds+=1 else: result="Entry not valid" except: result="Entry not valid" resultLabel.config(text=result) scoreLabel.config(text=str(score)+"/"+str(rounds)) guessBox.delete(0,tk.END) guessLabel=tk.Label(window,text="Enter a number from 1 to"+str(maxNo)) guessBox=tk.Entry(window) resultLabel=tk.Label(window) scoreLabel=tk.Label(window) button=tk.Button(window,text="guess",command=buttonClick) guessLabel.pack() guessBox.pack() resultLabel.pack() scoreLabel.pack() button.pack() window.mainloop()‘‘‘ ‘‘‘import Tkinter as tk window=tk.Tk() slider=tk.Scale(window,from_=0,to=100) slider.pack() tk.mainloop()
滚动条的创建与使用
import Tkinter as tk window=tk.Tk() slider=tk.Scale(window,from_=0,to=100) slider.pack() tk.mainloop()
画布的创建
import Tkinter as tk window=tk.Tk() colour="#FF0000" canvas=tk.Canvas(window,height=300,width=300,bg=colour) canvas.pack() window.mainloop()
颜色选择器：画布与滚动条的配合使用
注：通过三个滚动条的选择从而决定三原色红，绿，蓝三个颜色的占用，从而组成喜欢的颜色。而在实际画画中，所有的颜色由红，黄，蓝混合组成。
import Tkinter as tk window=tk.Tk() def sliderUpdate(source): red=redSlider.get() green=greenSlider.get() blue=blueSlider.get() colour="#%02x%02x%02x"%(red,green,blue) canvas.config(bg=colour) redSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate) greenSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate) blueSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate) canvas=tk.Canvas(window,width=200,height=200) redSlider.grid(row=1,column=1) greenSlider.grid(row=1,column=2) blueSlider.grid(row=1,column=3) canvas.grid(row=2,column=1,columnspan=3) tk.mainloop()
改进：添加一个文本框用来显示三原色的选择（16进制）
import Tkinter as tk window=tk.Tk() def sliderUpdate(source): red=redSlider.get() green=greenSlider.get() blue=blueSlider.get() colour="#%02x%02x%02x"%(red,green,blue) canvas.config(bg=colour) hexText.delete(0,tk.END) hexText.insert(0,colour) redSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate) greenSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate) blueSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate) canvas=tk.Canvas(window,width=200,height=200) hexText=tk.Entry(window) redSlider.grid(row=1,column=1) greenSlider.grid(row=1,column=2) blueSlider.grid(row=1,column=3) canvas.grid(row=2,column=1,columnspan=3) hexText.grid(row=3,column=1,columnspan=3) tk.mainloop()
一个计点击速度的游戏：记录点击的次数，直到达到目地数，输出所花费时间
import Tkinter as tk import time window=tk.Tk() clicks=0 start=0 goal=10 def buttonClick(): global clicks global start if clicks==0: start=time.time() clicks=clicks+1 elif clicks+1>=goal: score=time.time()-start label.config(text="Time: "+str(score)) clicks=0 else: clicks=clicks+1 slider.set(clicks) button=tk.Button(window,text="Click me",command=buttonClick) slider=tk.Scale(window,from_=0,to=goal) label=tk.Label(window) button.pack() slider.pack() label.pack() window.mainloop()
