PyQt5 QCalendarWidget – 获取最大高度

在本文中，我们将了解如何获得 QCalendarWidget 的最大高度。日历的最大高度是它不能进一步扩展的高度，默认情况下，当我们在布局内创建日历时，当窗口得到扩展时，日历大小也会增加，因此需要设置最大高度。我们可以在setMaximumHeight的帮助下设置最大高度

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

Syntax : calendar.maximumHeight()

Argument : It takes no argument

Return : It return integer

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
  
# 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 tot he layout
        layout.addWidget(self.calendar)
  
        # setting maximum height of the calendar
        self.calendar.setMaximumHeight(500)
  
        # creating a label
        label = QLabel(self)
  
        # adding label to the layout
        layout.addWidget(label)
  
        # getting maximum height
        value = self.calendar.maximumHeight()
  
        # setting text to the label
        label.setText("Maximum Height  : " + str(value))
  
        # 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 ：
