PyQt5 QCalendarWidget – 获取最小日期

在本文中，我们将了解如何获取 QCalendarWidget 的最小日期。 QCalendarWidget 的最小日期限制用户选择小于最小日期，即用户只能选择大于指定最小日期的日期。低于最短日期的日期将被禁用。我们使用 setMinimumDate 方法来设置最大日期。

In order to do this we will use minimumDate method with the QCalendarWidget object.
Syntax : calendar.minimumDate()
Argument : It takes no argument
Return : It return QDate object

编程需要懂一点英语

下面是实现

Python3

# 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, 600, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for components
    def UiComponents(self):
 
        # creating a QCalendarWidget object
        calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        calendar.setGeometry(10, 10, 400, 250)
 
        # lower bound date
        l_date = QDate(2020, 6, 5)
 
        # setting minimum date
        calendar.setMinimumDate(l_date)
 
        # creating a label
        label = QLabel(self)
 
        # setting geometry to the label
        label.setGeometry(100, 280, 250, 60)
 
        # making label multi line
        label.setWordWrap(True)
 
        # getting minimum date
        value = calender.minimumDate()
 
        # setting text to the label
        label.setText("Minimum 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：
