PyQt5 QCalendarWidget - 启用/禁用自动填充背景属性

在本文中，我们将看到如何启用或禁用 QCalendarWidget 的自动填充属性，该属性将导致 Qt 在调用绘制事件之前填充日历的背景。使用的颜色由 QPalette 定义。默认情况下，此属性为 false。
此属性应与 Qt 样式表一起小心处理。当日历具有具有有效背景或边框图像的样式表时，此属性将自动禁用。

In order to do this we will use setAutoFillBackground method with the QCalendarWidget object.
Syntax : calendar.setAutoFillBackground(True)
Argument : It takes bool as argument
Return : It return None 
 

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, 10, 400, 250)
 
        # setting style sheet
        self.calendar.setStyleSheet("background : lightgreen;")
 
        # enabling auto fill background
        self.calendar.setAutoFillBackground(True)
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
 
# start the app
sys.exit(App.exec())

输出 ：
