Pyside6中如何销毁终止的线程:
在PySide6中,要终止一个线程可以使用stop函数,这个函数能够在任何位置终止线程。具体的实现可以使用信号和槽,首先在需要终止的地方,发送一个信号,然后在槽函数中使用stop函数终止线程。代码示例如下:
```
import threading
from PySide6.QtCore import QObject, Signal, Slot
class WorkerThread(QObject):
finished = Signal()
error = Signal(tuple)
progress = Signal(int)
def __init__(self, func, *args, **kwargs):
super().__init__()
self.func = func
self.args = args
self.kwargs = kwargs
def run(self):
try:
result = self.func(*self.args, **self.kwargs)
except:
self.error.emit(sys.exc_info())
else:
self.finished.emit(result)
def stop(self):
self.terminate()
class MainWindow(QObject):
def __init__(self):
super().__init__()
self.thread = QThread()
self.worker = WorkerThread(self.do_work)
self.worker.moveToThread(self.thread)
self.worker.finished.connect(self.thread.quit)
self.worker.finished.connect(self.worker.deleteLater)
self.thread.finished.connect(self.thread.deleteLater)
self.worker.error.connect(self.show_error)
self.thread.started.connect(self.worker.run)
self.thread.finished.connect(self.worker.deleteLater)
self.thread.finished.connect(self.thread.deleteLater)
self.thread.start()
def do_work(self):
for i in range(100):
time.sleep(0.1)
self.worker.progress.emit(i)
return 'Finished!'
def stop_worker(self):
self.worker.stop()
if __name__ == '__main__':
app = QApplication(sys.argv)
main_window = MainWindow()
sys.exit(app.exec_())
```
在上面的代码中,我们定义了一个WorkerThread类,用来处理需要执行的函数。在主窗口的构造函数中,我们创建了一个新的线程,并且把我们的WorkerThread类移动到这个线程中。我们使用finished信号来终止线程,并且在终止后删除线程和WorkerThread对象,并且在需要终止的地方调用stop函数即可。
