使用Python做一个监听鼠标键盘（全局的）的代码实现。

代码一：这个代码较为简单，只实现了监听键盘。不过感觉上，它比“代码二”，更为基础。

#!/usr/bin/env python
#--*-- coding: UTF-8 --*--

from evdev import InputDevice;
from select import select;

def detectInputKey():
    dev = InputDevice('/dev/input/event4');
    while True:
        select([dev], [], []);
        for event in dev.read():
            print "code:%s value:%s" % (event.code, event.value)

detectInputKey();

代码二：这个代码用到的组件，感觉比“代码一”更为高级。

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#

import pythoncom
import pyHook

def onMouseEvent(event):
    # 监听鼠标事件
    print "MessageName:", event.MessageName
    print "Message:", event.Message
    print "Time:", event.Time
    print "Window:", event.Window
    print "WindowName:", event.WindowName
    print "Position:", event.Position
    print "Wheel:", event.Wheel
    print "Injected:", event.Injected
    print "---"

    # 返回 True 以便将事件传给其它处理程序
    # 注意，这儿如果返回 False ，则鼠标事件将被全部拦截
    # 也就是说你的鼠标看起来会僵在那儿，似乎失去响应了
    return True

def onKeyboardEvent(event):
    # 监听键盘事件
    print "MessageName:", event.MessageName
    print "Message:", event.Message
    print "Time:", event.Time
    print "Window:", event.Window
    print "WindowName:", event.WindowName
    print "Ascii:", event.Ascii, chr(event.Ascii)
    print "Key:", event.Key
    print "KeyID:", event.KeyID
    print "ScanCode:", event.ScanCode
    print "Extended:", event.Extended
    print "Injected:", event.Injected
    print "Alt", event.Alt
    print "Transition", event.Transition
    print "---"

    # 同鼠标事件监听函数的返回值
    return True

def main():
    # 创建一个“钩子”管理对象
    hm = pyHook.HookManager()

    # 监听所有键盘事件
    hm.KeyDown = onKeyboardEvent
    # 设置键盘“钩子”
    hm.HookKeyboard()

    # 监听所有鼠标事件
    hm.MouseAll = onMouseEvent
    # 设置鼠标“钩子”
    hm.HookMouse()

    # 进入循环，如不手动关闭，程序将一直处于监听状态
