PyQt5 QDateEdit – 获取用户可以输入的最小日期

在本文中,我们将了解如何设置 QDateEdit 的最小日期。有时需要设置最小日期,以便用户无法输入超出最小日期的日期,例如当要求用户输入酒店预订日期时,不应允许用户输入过去的日期,然后需要设置最小值日期出现。可以借助setMinimumDate方法设置最小日期。

为了做到这一点,我们使用minimumDate方法和 QDateEdit 对象

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)
  
        # setting geometry of the date edit
        date.setGeometry(100, 100, 200, 40)
  
        # alignment
        a_flag = Qt.AlignCenter
  
        # setting alignment of date
        date.setAlignment(a_flag)
  
        # QDate object
        d = QDate(2020, 1, 1)
  
        # setting minimum date
        date.setMinimumDate(d)
          
  
        # text
        text = "Geek date edit"
  
        # setting name
        date.setAccessibleName(text)
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry
        label.setGeometry(100, 150, 200, 60)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting minimum date
        value = date.minimumDate()
  
        # setting text to the label
        label.setText("Min Date : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
