Python GUI之tkinter布局管理教程

from tkinter import *
root = Tk()
 
#创建三个 Label 分别添加到root窗体中 
#Label是一种用来显示文字或者图片的组件
Label(root,text = 'pack1',bg = 'red').pack() 
Label(root, text = 'pack2', bg = 'blue').pack() 
Label(root, text = 'pack3', bg = 'green').pack() 
 
root.mainloop()

from tkinter import *    #注意模块导入方式，否则代码会有差别
 
class App:
    def __init__(self, master):
        #使用Frame增加一层容器
        fm1 = Frame(master)
        #Button是一种按钮组件，与Label类似，只是多出了响应点击的功能
        Button(fm1, text='Top').pack(side=TOP, anchor=W, fill=X, expand=YES)
        Button(fm1, text='Center').pack(side=TOP, anchor=W, fill=X, expand=YES)
        Button(fm1, text='Bottom').pack(side=TOP, anchor=W, fill=X, expand=YES)
        fm1.pack(side=LEFT, fill=BOTH, expand=YES)
 
        fm2 = Frame(master)
        Button(fm2, text='Left').pack(side=LEFT)
        Button(fm2, text='This is the Center button').pack(side=LEFT)
        Button(fm2, text='Right').pack(side=LEFT)        
        fm2.pack(side=LEFT, padx=10)
        
root = Tk()
root.title("Pack - Example")
display = App(root)
root.mainloop()
