PyQt5应用程序-使用计时器通过循环运行函数会使其“冻结”

import sys
import time
from PyQt5.QtCore import QTimer, QThread, pyqtSignal
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel

class WorkerThread(QThread):
    finished = pyqtSignal()

    def run(self):
        # 在这里编写需要循环运行的函数
        for i in range(10):
            print(i)
            time.sleep(1)
        self.finished.emit()

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.label = QLabel("Count: 0", self)
        self.label.setGeometry(50, 50, 100, 30)

        self.timer = QTimer(self)
        self.timer.timeout.connect(self.update_count)
        self.timer.start(1000)

        self.worker_thread = WorkerThread()
        self.worker_thread.finished.connect(self.worker_finished)
        self.worker_thread.start()

    def update_count(self):
        # 更新计数器显示
        count = int(self.label.text().split(":")[1]) + 1
        self.label.setText(f"Count: {count}")

    def worker_finished(self):
        # 在工作线程完成后的处理
        print("Worker finished")

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())
