Question

我正在使用PySide在python中编写一个程序，我解析一个IP地址文件并ping它们以查看它们是否已启动，并将其显示在QTreeWidget中。我遇到的问题是程序在输出数据之前ping所有客户端，导致程序在ping时“冻结”。如何在不冻结程序的情况下ping IP地址并打印输出？

您可以从QThread ping您的地址，例如：

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

from PyQt4 import QtCore

class PingThread(QtCore.QThread):
    addressState = QtCore.pyqtSignal(bool, QtCore.QString)

    def __init__ (self):
       super(PingThread, self).__init__()

    def start(self, addressList):
       self.addressList = addressList

       super(PingThread, self).start()

    def run(self):
        for address in self.addressList:
            status = True
            ping   = os.popen('ping -q -c2 {0}'.format(address), 'r')
            while True:
               line = ping.readline()
               if not line:
                   break
               if line.find('100% packet loss') > 0:
                   status = False

            self.addressState.emit(status, address)

你的主要小部件中需要这样的东西：

self.pingThread = PingThread()
self.pingThread.addressState.connect(self.on_pingThread_addressState)
self.pingThread.start(myListOfAddresses)

当然是一个名为on_pingThread_addressState的广告位。

Pyside ping了ip的列表
