Question

我尝试使用moveToThread（）创建QThread，但是不起作用。如果我使用扩展QThread的Class，它可以工作。为什么我不能使用moveToThread运行QThread？

我找到了this example，但看不出有什么区别。还是环境问题？

env：python3.6.6 32bits，赢得10

TestThread.py

from PySide2 import QtCore
# try:
#     from PySide2.QtCore import QString
# except:
#     QString = str
import sys,time

class TestThread(QtCore.QObject):

    def __init__(self, parent=None):
        super(TestThread, self).__init__(parent)

    @QtCore.Slot()
    def longRun(self):
        while True:
            print('abcxxx')
            time.sleep(3)

# class TestThread(QtCore.QThread):

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

#     def __del__(self):
#         self.quit()
#         self.wait()

#     def run(self):
#         while True:
#             print('abc')
#             time.sleep(3)

TestMain.py

from PySide2 import QtCore, QtGui, QtWidgets
# try:
#     from PySide2.QtCore import QString
# except:
#     QString = str

from TestUI import TestUI
import sys
from TestThread import TestThread

class TestMain(QtWidgets.QMainWindow, TestUI):

    def __init__(self, parent=None):
        super(__class__, self).__init__(parent)
        self.setupUi(self)
        self.testBtn.clicked.connect(self.testclick)

    def testclick(self):
        print(123)
        t = TestThread()
        thr = QtCore.QThread(self)
        t.moveToThread(thr)
        thr.started.connect(t.longRun)
        thr.start()

        # t = TestThread(self)
        # t.start()

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    ui = TestMain()
    ui.show()
    sys.exit(app.exec_())

TestUI.py

from PySide2 import QtCore, QtGui, QtWidgets

class TestUI(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(100, 100)
        self.centralWidget = QtWidgets.QWidget(MainWindow)
        self.centralWidget.setObjectName("centralWidget")

        self.testBtn = QtWidgets.QPushButton(self.centralWidget)
        self.testBtn.setObjectName("testBtb")

        MainWindow.setCentralWidget(self.centralWidget)

        self.retranslateUi(MainWindow)

    def retranslateUi(self, MainWindow):
        self.testBtn.setText(QtWidgets.QApplication.translate("MainWindow", "Test", None, -1))

PySide2-带moveToThread的QThread不起作用
