PyQt5 Qthread Create - qt

Question

AttributeError: type object 'QThread' has no attribute 'create'
Here is my code.
from PyQt5.QtCore import QThread
def fun(num):
print(num)
thread1 = QThread.create(fun)
thread1.start()
But Qt documentation says there is a function called create since Qt 5.10. I am using PyQt5 5.11.3. Someone please help me with this.

You can use worker objects by moving them to the thread using QObject::moveToThread().
from PyQt5.QtCore import QObject, pyqtSignal, QThread, QTimer
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QProgressBar, QPushButton
class Worker(QObject):
valueChanged = pyqtSignal(int) # Value change signal
def run(self):
print('thread id ->', int(QThread.currentThreadId()))
for i in range(1, 101):
print('value =', i)
self.valueChanged.emit(i)
QThread.msleep(100)
class Window(QWidget):
def __init__(self, *args, **kwargs):
super(Window, self).__init__(*args, **kwargs)
layout = QVBoxLayout(self)
self.progressBar = QProgressBar(self)
self.progressBar.setRange(0, 100)
layout.addWidget(self.progressBar)
layout.addWidget(QPushButton('Open thread', self, clicked=self.onStart))
# Current thread id
print('main id = ', int(QThread.currentThreadId()))
# Start thread update progress bar value
self._thread = QThread(self)
self._worker = Worker()
self._worker.moveToThread(self._thread) # Move to thread to execute
self._thread.finished.connect(self._worker.deleteLater)
self._worker.valueChanged.connect(self.progressBar.setValue)
def onStart(self):
print('main id -> ', int(QThread.currentThreadId()))
self._thread.start() # Start thread
QTimer.singleShot(1, self._worker.run)
def closeEvent(self, event):
if self._thread.isRunning():
self._thread.quit()
del self._thread
del self._worker
super(Window, self).closeEvent(event)
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
w = Window()
w.show()
w.setWindowTitle('Demo moveToThread')
sys.exit(app.exec_())
