当我调用Continusread
方法时,我试图在我的用户界面中获得Count_total_value
的值(根据我想做的,它应该是"toto"
),但它总是显示默认值"azerty"
。你能告诉我哪里错了吗?在
这是我的代码:
#!/usr/bin/env python3
from PyQt4 import QtCore, QtGui
import sys
import os
import subprocess
import time
import threading
from ctypes import *
import ctypes
#import Converted Python UI File
from test_error_rx import Ui_MainWindow
class MyThread(QtCore.QThread):
Count_total_valuechanged = QtCore.pyqtSignal(str)
def __init__(self, parent=None):
super(MyThread, self).__init__(parent=parent)
self.Count_total_value = 'Azerty'
def run(self):
##do things to calculate Count_total_value
Count_total_value='toto'
self.Count_total_valuechanged.emit((self.Count_total_value))
time.sleep(0.1)
class Main( QtGui.QMainWindow,QtGui.QWidget):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
# Connect the Buttons
QtCore.QObject.connect(self.ui.Continusread,QtCore.SIGNAL("clicked()"),self.Continusread)
self.__thread = MyThread(self)
self.__thread.Count_total_valuechanged.connect(self.ui.Count_total.setText)
def Continusread(self):
self.__thread.start()
def main():
app = QtGui.QApplication(sys.argv)
window = Main()
window.show()
sys.exit(app.exec_())
if __name__ == "__main__":
main()
在线程类的
run()
方法中,MyThread
将Count_total_value='toto'
设置为self.Count_total_value='toto'
。在请注意,在stackoverflow上发布时,您应该:
