PyQt5 QCalendarWidget 设置背景角色
在这篇文章中,我们将看到如何为QCalendarWidget设置背景角色。背景角色定义了来自日历调色板的笔刷,它被用来渲染背景。如果没有设置明确的背景角色,日历就会继承其父部件的背景角色。
为了做到这一点,我们将使用QCalendarWidget对象的setBackgroundRole方法。
语法: calendar.setBackgroundRole(palette_object)
参数: 它需要QPalette.ColorRole对象的参数
返回: 它返回无
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, 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)
# enabling auto fill background
self.calendar.setAutoFillBackground(True)
# setting background role
self.calendar.setBackgroundRole(QPalette.Base)
# getting palette and setting color to the background to it
p = self.calendar.palette()
p.setColor(self.calendar.backgroundRole(), Qt.yellow)
self.calendar.setPalette(p)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
