我希望用户能够在怎么开始的实现它？在

我的代码是：# -*- coding: utf-8 -*-

from PySide import QtCore, QtGui

try:

job = job_queue.get(block=False)

result_queue.put(do_work())

pass

job_queue.put(None)

self.workers = []

for i in range(6):

tmp = multiprocessing.Process(target=manual_function, args=(job_queue, result_queue))

tmp.start()

self.workers.append(tmp)

def paused(self):

'''

pause / resumme ?????????????????????????

'''

def stop(self):

for worker in self.workers:

print ("end")

worker.terminate()

worker.join()

class MainWindow(QtGui.QMainWindow):

def __init__(self, parent=None):

QtGui.QMainWindow.__init__(self, parent)

self.ui = Ui_MainWindow()

self.ui.setupUi(self)

self.connect(self.ui.actionStart, QtCore.SIGNAL('triggered()'),self.start)

window = MainWindow()

window.show()

sys.exit(app.exec_())
