在单独的线程中运行 pyQT GUI 主应用程序 [英] Run pyQT GUI main app in seperate Thread

问题描述

我正在尝试在我已经建立的应用程序中添加 PyQt GUI 控制台.但是 PyQt GUI 阻止了整个应用程序，使其无法完成其余工作.我尝试使用 QThread，但它是从 mainWindow 类调用的.我想要的是在单独的线程中运行 MainWindow 应用程序.

I am trying to add a PyQt GUI console in my already established application. But the PyQt GUI blocks the whole application making it unable to do rest of the work. I tried using QThread, but that is called from the mainWindow class. What I want is to run the MainWindow app in separate thread.

def main()
      app = QtGui.QApplication(sys.argv)
      ex = Start_GUI()
      app.exec_()  #<---------- code blocks over here !

      #After running the GUI, continue the rest of the application task
      doThis = do_Thread("doThis")
      doThis.start()
      doThat = do_Thread("doThat")
      doThat.start()

我的应用程序已经使用 Python 线程，所以我的问题是，以线程形式实现此过程的最佳方法是什么.

My application already uses Python Threads, So my question is, what is the best approach to achieve this process in a threaded form.

推荐答案

一种方法是

import threading

def main()
      app = QtGui.QApplication(sys.argv)
      ex = Start_GUI()
      app.exec_()  #<---------- code blocks over here !

#After running the GUI, continue the rest of the application task

t = threading.Thread(target=main)
t.daemon = True
t.start()

doThis = do_Thread("doThis")
doThis.start()
doThat = do_Thread("doThat")
doThat.start()

这将从您的主应用程序开始，并让您在下面的代码中继续执行您想做的所有其他事情.

this will thread your main application to begin with, and let you carry on with all the other stuff you want to do after in the code below.
