PyQt5 QCalendarWidget – 设置最大宽度

在本文中，我们将了解如何为 QCalendarWidget 设置最大宽度。日历的最大宽度是不能再扩展的宽度，默认情况下，当我们在布局中创建日历时，当窗口扩展时，日历大小也会增加，因此需要设置最大宽度。

In order to do this we will use setMaximumWidth method with the QCalendarWidget object.
Syntax : calendar.setMaximumWidth(500)
Argument : It takes integer as argument
Return : It return None

编程需要懂一点英语

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
 
# QCalendarWidget Class
class Calendar(QCalendarWidget):
 
    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)
        self.setMouseTracking(True)
 
 
class Window(QMainWindow):
 
    def __init__(self):
        super().__init__()
 
        # setting title
        self.setWindowTitle("Python ")
 
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
 
    # method for components
    def UiComponents(self):
 
        # creating a layout
        layout = QVBoxLayout()
 
        # creating a QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)
 
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
 
        # adding calendar to  the layout
        layout.addWidget(self.calendar)
 
        # setting maximum width of the calendar
        self.calendar.setMaximumWidth(500)
 
        # setting layout
        widget = QWidget()
        widget.setLayout(layout)
        self.setCentralWidget(widget)
 
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：

当窗口被拉伸时
