将某些算法类中的程序逻辑嵌入到pyqt4用户界面中的最佳方式是什么

from PyQt4.QtCore import QObject, pyqtSignal

class Algorithm(QObject):
    executeFinished = pyqtSignal()  # 定义一个信号

    def execute(self):
        # 算法逻辑的执行
        # ...

        self.executeFinished.emit()  # 发射信号

from PyQt4.QtCore import pyqtSlot
from PyQt4.QtGui import QMainWindow, QPushButton

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

        self.algorithm = Algorithm()

        button = QPushButton("执行算法", self)
        button.clicked.connect(self.executeAlgorithm)  # 连接按钮的点击事件与槽函数

    @pyqtSlot()
    def executeAlgorithm(self):
        self.algorithm.execute()

    @pyqtSlot()
    def handleAlgorithmFinished(self):
        # 算法执行完成后的处理逻辑
        # ...

app = QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())
