PyQt5 QCalendarWidget – 设置其布局

在本文中，我们将了解如何将布局设置为 QCalendarWidget。为了做到这一点，我们使用 setLayout 方法，如果日历上已经安装了布局管理器，QWidget 不会让我们安装另一个。我们必须先删除或更新现有的布局管理器（由 layout() 返回），然后才能使用新布局调用 setLayout()。

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

编程需要懂一点英语

实施步骤：
1.创建一个主窗口
2. 创建一个日历小部件并为其设置几何图形
3.获取日历的布局
4.创建标签并设置其属性
5. 使用 addWidget 方法将此标签添加到布局中
6.将此布局设置回日历

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, 300)
 
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
 
        # getting the current lay out
        layout = self.calendar.layout()
 
        # creating a label
        label = QLabel("GeeksforGeeks", self)
 
        # setting alignment
        label.setAlignment(Qt.AlignCenter)
 
        # setting style sheet to the label
        label.setStyleSheet("QLabel"
                            "{"
                            "border : 1px solid darkgrey;"
                            "background : lightgrey;"
                            "}")
 
        # adding label to the layout
        layout.addWidget(label)
 
        # setting layout back to calendar
        self.calendar.setLayout(layout)
 
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
