继续请教个问题。任务WORK在thread里面运行后，如果想停止任务(而不是简单终止线程)，用线程安全的方式用槽信号来触发任务停止条件时，不起作用，因为线程内需要等任务(dowork)自然完成后，才会接收其他槽信号队列。如果直接用跨线程的方式执行实例self.work.stop，反而能够立即停止任务。只是隐约感觉这种方式不太正规，请问有没有其他方式？
class Work(QObject):
update_process = pyqtSignal(int)
update_completed = pyqtSignal()
.....ini_thing....
def dowork(self):
self.var = 0
while self.var
self.var += 1
self.update_process.emit(self.var)
self.update_completed.emit() # -----------任务结束
def stopwork(self):
self._running = false
class UiTest(QDialog):
.....UI-thing....
self.work = Work()
self.thread = QThread()
self.work.moveToThread(self.thread)
self.thread.started.connect(self.work.dowork)
self.work.update_process.connect(self.currentStep.setValue)
self.worker.update_completed.connect(lambda:print('work finished'))
self.btnDoWork.clicked.connect(self.work.dowork)
1. self.btnStopWork.clicked.connect(self.work.stopwork) -- 通过槽触发任务
2. self.btnStopWork.clicked.connect(self.stopwork) -- 直接跨线程介入任务
self.btnStopThread.clicked.connect(self.stop_thread)
self.btnStartThread.clicked.connect(self.start_thread)
self.thread.finished.connect(lambda: print('thread finished'))
def start_thread(self):
self.thread.start()
def stop_thread(self):
self.thread.quit()
self.thread.wait()
def stop_work(self): -------------直接跨线程介入任务
self.work.stopwork
