PyQt5 QCalendarWidget – 确保绘制事件

在本文中，我们将了解如何确保 QCalendarWidget 的绘制事件。在画家事件的帮助下，我们可以绘制用户想要的日历，但有时需要重新绘制旋转框以确保画家事件的动作。

In order to do this we will use repaint method with the QCalendarWidget object.
Syntax : calendar.repaint()
Argument : It takes no argument
Return : It returns None

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
        self.calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        self.calendar.setGeometry(50, 50, 400, 250)
 
        # setting style sheet
        self.calendar.setStyleSheet("background : lightgreen;")
 
        # ensuring paint event
        self.calendar.repaint()
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
