PyQt5 QCalendarWidget – 访问字体指标

在本文中，我们将了解如何获取 QCalendarWidget 的字体指标。字体是字体的特定大小、重量和样式。每种字体都是一组匹配的类型，每个字形一个。通过改变字体，我们可以改变日历中文本的样式。我们可以使用setFont方法更改/设置字体。字体度量计算给定日历字体的字符和字符串的大小。

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

Syntax : calendar.fontMetrics()

Argument : It takes no argument

Return : It return QFontMetrics object

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
  
  
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.calender = QCalendarWidget(self)
  
        # setting geometry to the calendar
        self.calender.setGeometry(50, 10, 400, 250)
  
        # setting cursor
        self.calender.setCursor(Qt.PointingHandCursor)
  
        # font
        font = QFont('Times', 5)
  
        # setting font to the calendar
        self.calender.setFont(font)
  
        # creating label to show the properties
        self.label = QLabel(self)
  
        # setting geometry to the label
        self.label.setGeometry(100, 280, 250, 60)
  
        # making label multi line
        self.label.setWordWrap(True)
  
        # getting font Metrics Object
        value = self.calender.fontMetrics()
  
        # setting text to the label
        self.label.setText("Font Metrics : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
