python – pyqt QThread阻塞主线程

我的问题是,无论我如何实现线程,它实际上都没有线程 – 一旦线程启动,UI就会被锁定.我已阅读每个教程并发布有关此内容的信息,我现在正在求助社区我试着解决我的问题,因为我不知所措！

最初我尝试了继承QThread,直到互联网说这是错误的.然后我尝试了moveToThread方法,但它没有区别.

初始化代码：

loadingThreadObject = LoadThread(arg1)
loadingThread = PythonThread()
loadingThreadObject.moveToThread(loadingThread)
loadingThread.started.connect(loadingThreadObject.load)
loadingThread.start()

PythonThread类(显然QThreads在pyQt中被窃听并且除非你这样做否则不启动)：

class PythonThread (QtCore.QThread):
    def __init__(self,parent=None):
        QtCore.QThread.__init__(self,parent)

    def start(self):
        QtCore.QThread.start(self)

    def run(self):
        QtCore.QThread.run(self)

LoadThread类：

class LoadThread (QtCore.QObject):
    results = QtCore.Signal(tuple)

    def __init__ (self,arg):
         # Init QObject
         super(QtCore.QObject,self).__init__()

         # Store the argument
         self.arg = arg

    def load (self):
         #
         # Some heavy lifting is done
         #

         loaded = True
         errors = []

         # Emits the results
         self.results.emit((loaded,errors))

任何帮助是极大的赞赏！

谢谢.
