PyQt5 QDateEdit - Time Changed Signal

The QDateEdit widget in PyQt5 is designed to allow the user to edit dates with a date-time edit box or through a pop-up calendar. However, QDateEdit only deals with dates and not times. If you want to work with times or date-times, you should use QTimeEdit for times or QDateTimeEdit for combined date-times.

The QDateEdit widget itself doesn't have a timeChanged signal since it's focused only on dates. But QTimeEdit has a timeChanged signal, and QDateTimeEdit has both dateChanged and timeChanged signals.

Here's a brief demonstration on how to use the timeChanged signal with QDateTimeEdit:

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QDateTimeEdit, QVBoxLayout, QWidget from PyQt5.QtCore import QDateTime class MainWindow(QMainWindow): def __init__(self): super(MainWindow, self).__init__() layout = QVBoxLayout() self.dateTimeEdit = QDateTimeEdit(QDateTime.currentDateTime(), self) layout.addWidget(self.dateTimeEdit) # Connect the timeChanged signal self.dateTimeEdit.timeChanged.connect(self.onTimeChanged) container = QWidget() container.setLayout(layout) self.setCentralWidget(container) def onTimeChanged(self, time): print("Time changed:", time.toString()) app = QApplication(sys.argv) window = MainWindow() window.show() sys.exit(app.exec_()) 

In this example, the onTimeChanged method will be triggered whenever the time in the QDateTimeEdit widget is changed by the user.
