  <P>
    感谢Bazza的意见。你的回答帮助我找到解决问题的方法。在搜索了我如何发射Qevent之后;我找到了以下示例

     并解决了这个问题。
最终代码如下所示：

   <pre>
    <code>
      import pyforms
from   pyforms          import BaseWidget
from   pyforms.controls import ControlTextArea
from   pyforms.controls import ControlButton
import threading
import zmq
from PyQt5 import QtCore

class ZeroMQ_Listener(QtCore.QObject):

message = QtCore.pyqtSignal(str)

def __init__(self):

QtCore.QObject.__init__(self)

# Socket to talk to server
        context = zmq.Context()
        self.socket = context.socket(zmq.PULL)
        self.socket.connect('tcp://127.0.0.1:5014')
        print('connected!')
        self.running = True

def loop(self):
        while self.running:
            string = self.socket.recv_string()
            self.message.emit(string)

class SimpleExample1(BaseWidget):

def __init__(self):
        super(SimpleExample1,self).__init__('Simple example 1')

#Definition of the forms fields
        self._controltextarea     = ControlTextArea('textarea to show incoming zmq messages')
        self._button        = ControlButton('Press this button')

message = QtCore.pyqtSignal(str)
        self.thread = QtCore.QThread()
        self.zeromq_listener = ZeroMQ_Listener()

self.zeromq_listener.moveToThread(self.thread)

self.thread.started.connect(self.zeromq_listener.loop)
        self.zeromq_listener.message.connect(self.signal_received)

QtCore.QTimer.singleShot(0, self.thread.start)

def signal_received(self, message):
        self._controltextarea.__add__(message)

#Execute the application
if __name__ == "__main__":
    guiThread = threading.Thread(target=pyforms.start_app( SimpleExample1 ))

guiThread.start()
