PyQt5 QDateEdit – 递增日期

在本文中，我们将看到如何增加 QDateEdit 的日期。步进更新意味着增加日期，它增加当前选定的部分，即日、月或年。向上箭头按钮执行相同的操作，尽管我们可以删除该按钮并制作我们自己的按钮。

为了做到这一点，我们使用带有 QDateEdit 对象的stepUp方法

Syntax : date.stepUp()

Argument : It takes no argument

Return : It returns None

下面是实现

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating a QDateEdit widget
        date = QDateEdit(self)
  
        # removing buttons
        date.setButtonSymbols(2)
  
        # setting geometry of the date edit
        date.setGeometry(100, 100, 150, 40)
  
        # creating a label
        push = QPushButton("Step Up", self)
  
        # setting geometry of the push button
        push.setGeometry(100, 170, 100, 30)
  
        # adding action to the push button when it get clicked
        push.clicked.connect(lambda: push_method())
  
        # method called by the push button
        def push_method():
  
            # steping up the date
            date.stepUp()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
