Python Pyqt5 QDateEdit Get Date String

Question

我正在尝试使用 Pyqt5 QDateEdit 构建日期打印机。我可以弹出日历，但我想在控制台(或窗口中的标签(中写入单击日期的字符串。我尝试了print(self.calendarWidget().document().toPlainText())或print(self.calendarWidget().currentText())但没有用。

我使用此代码;

from PyQt5 import QtCore, QtWidgets

class DateEdit(QtWidgets.QDateEdit):
popupSignal = QtCore.pyqtSignal()
def __init__(self, parent=None):
super(DateEdit, self).__init__(parent)
self.setCalendarPopup(True)
self.calendarWidget().installEventFilter(self)
def eventFilter(self, obj, event):
if self.calendarWidget() is obj and event.type() == QtCore.QEvent.Show:
self.popupSignal.emit()
return super(DateEdit, self).eventFilter(obj, event)

if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = DateEdit()
w.popupSignal.connect(lambda: print("popup"))
w.show()
sys.exit(app.exec_())

它的语法是什么？我没有找到足够的文档。你能帮忙吗？

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import *
class MyWindow(QtWidgets.QWidget):
def __init__(self, parent=None):
super(MyWindow, self).__init__(parent)
self.dateEdit = QDateEdit(self)
self.lbl = QLabel()
self.dateEdit.setMaximumDate(QtCore.QDate(7999, 12, 28))
self.dateEdit.setMaximumTime(QtCore.QTime(23, 59, 59))
self.dateEdit.setCalendarPopup(True)
layout = QGridLayout()
layout.addWidget(self.dateEdit)
layout.addWidget(self.lbl)
self.setLayout(layout)

self.dateEdit.dateChanged.connect(self.onDateChanged)
def onDateChanged(self, qDate):
print('{0}/{1}/{2}'.format(qDate.day(), qDate.month(), qDate.year()))

if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
app.setApplicationName('MyWindow')
main = MyWindow()
main.show()
sys.exit(app.exec_())
