PyQt5 QCalendarWidget – 确保绘画事件
在这篇文章中,我们将看到我们如何确保QCalendarWidget的绘画事件。在绘画事件的帮助下,我们可以把日历画成用户想要的样子,但有些时候需要重新画出旋转框,以确保绘画事件的动作。
为了做到这一点,我们将使用QCalendarWidget对象的repaint方法。
语法: calendar.repaint()
参数: 它不需要参数
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, 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 :
