在Python进程中打开GUI

Question

我有Python3.8中的代码，它启动一个主pyqt接口来配置一些参数，当用户准备好时，他们点击开始按钮，程序用自己的进程打开子窗口

我试着用QThreads来实现这一点，但是如果某个进程在某个地方卡住了，它会冻结整个应用程序，用户必须立即关闭所有子窗口，这种行为对用户体验非常不利。所以现在我尝试使用多进程，但是我不能让它工作

当我初始化该进程时，它运行良好，直到它到达我调用sub_window.show（）的那一行，向用户实际显示PyQt接口，但它没有通过那一行。我不知道我是否能在多进程中做到这一点，但我找不到关于这个问题的任何信息

对不起，我的英语不是我的主要语言

以下是一些重要部件的代码：

启动流程的主界面：

        p = Process(target=self.bot.startInterface)
        p.start()

和startInterface函数：

        app = QtWidgets.QApplication(sys.argv)
        app.setStyle('Fusion')
        
        self.main_interface = StatusWindow(self.index, self, self.master_interface)

        self.update_log.connect(self.main_interface.registerLog)
        self.unconnected.connect(self.main_interface.unconnected)


        self.main_interface.setModelItems(self.accounts.items())
        self.main_interface.start_time = datetime.now()

        
        self.main_interface.timer.timeout.connect(self.main_interface.updateStatus)
        self.main_interface.timer.setInterval(1000)
        QtCore.QTimer.singleShot(self.index*self.open_after, self.main_interface.timer.start)

        # Stops here
        self.main_interface.show()

        self.main_interface.botProcess = QThread()
        self.moveToThread(self.main_interface.botProcess)
        self.main_interface.botProcess.started.connect(self.main)
        self.main_interface.botProcess.start()

        sys.exit(app.exec_())

这是我的接口类

class StatusWindow(QMainWindow):
def __init__(self, index, app, master=None):
    self.index = index
    self.master = master
    self.accountStatus = {}
    self.start_time = 0

    self.botProcess = QThread()
