PyQt5 QCalendarWidget - 设置图形效果

在本文中，我们将了解如何为 QCalendarWidget 设置图形效果。图形效果是可以在精灵或舞台上使用的效果，以某种方式改变它们的外观。图形效果可以是任何颜色阴影。

In order to do this we will use setGraphicsEffect method with the QCalendarWidget object.

Syntax : calendar.setGraphicsEffect(effect)

Argument : It takes QGraphicEffect object as argument

Return : It return None

注意：此函数会将效果应用于日历本身及其所有子项。

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, 650, 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 cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # creating a color graphic effect
        color = QGraphicsColorizeEffect()
        color.setColor(Qt.green)
  
        # setting graphics to the calendar
        self.calendar.setGraphicsEffect(color)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
