This option controls how to draw the 3D border. It can be set to one of SUNKEN, RAISED, GROOVE, RIDGE, and FLAT.

事件和事件绑定

http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm

绑定的三种方式：

1、通过command = 回调函数连接事件（按钮级）

2、通过bind 绑定事件（按钮级）

3、通过协议protocol 去监听窗体改变来绑定事件（系统级）

import tkMessageBox

root= Tk()
'''
def button1Click():
    print('button clicked')

button = Button(text='hello', command=button1Click)
button.pack()
root.mainloop()
'''
def callback(event):

    frame.focus_set()
    print('clicked at:', event.x, event.y)
def key(event):
    print("pressed", repr(event.char))

frame = Frame(root,width=100,height=100)
frame.bind('<Button-1>',callback)
frame.bind('<Key>',key)
frame.pack()

root.protocol('WM_DELETE_WINDOW',)
root.mainloop()

效果：

command绑定事件的限制性  ： 标签没有command属性，没有办法绑定事件
