PyQt5 QCalendarWidget – 获取大小增量

在本文中，我们将了解如何获取 QCalendarWidget 的大小增量。当日历大小随主窗口大小变化而变化时，使用大小增量。默认情况下，对于新创建的日历，此属性包含宽度和高度为零的大小。

注意：大小增量在 Windows 下无效，X11 上的窗口管理器可能会忽略。

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

Syntax : calendar.sizeIncrement()

Argument : It takes no argument

Return : It return QSize object

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 size increment
        self.calendar.setSizeIncrement(QSize(20, 20))
  
        # creating a label
        label = QLabel(self)
  
        # adding label to the layout
        layout.addWidget(label)
  
        # getting size increment
        value = self.calendar.sizeIncrement()
  
        # setting text to the label
        label.setText("Size Increment : " + 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 ：
