如何检测QInputDialog中值的变化？

from PyQt5.QtWidgets import QInputDialog, QApplication

def handleValueChanged(value):
    print("Value changed:", value)

app = QApplication([])
inputDialog = QInputDialog()
inputDialog.valueChanged.connect(handleValueChanged)
inputDialog.exec_()

from PyQt5.QtWidgets import QInputDialog, QApplication
from PyQt5.QtCore import QEvent

class InputDialogFilter(QObject):
    def eventFilter(self, obj, event):
        if event.type() == QEvent.ValueChange:
            value = obj.textValue()
            print("Value changed:", value)
        return super().eventFilter(obj, event)

app = QApplication([])
inputDialog = QInputDialog()
filter = InputDialogFilter()
inputDialog.installEventFilter(filter)
inputDialog.exec_()
