from Tkinter import *

class App:

    def __init__(self, master):

        # frame  创建一个实例
        frame = Frame(master)

        # 使用pack方法使其可见
        frame.pack()

        # 定义按钮
        self.button = Button(
                # 使用系统命令 frame.quit
                frame, text = "QUIT", fg = "red", command = frame.quit
            )
        # 定义位置
        self.button.pack(side =  LEFT)

        # 定义另一个按钮，调用函数
        self.hi_there = Button(frame, text = "Hello" ,command = self.say_hi)
