PyQt5 QCalendarWidget 访问字体指标
在这篇文章中,我们将看到如何获得QCalendarWidget的字体度量。字体是一种特定大小、重量和风格的字体。每种字体都是一套匹配的字体,每个字形都有一块。通过改变字体,我们可以改变日历中出现的文字的风格。我们可以使用setFont方法改变/设置字体。字体指标计算出日历的特定字体的字符和字符串的大小。
为了做到这一点,我们将使用QCalendarWidget对象的fontMetrics方法。
语法: calendar.fontMetrics()
参数: 它不需要参数
返回: 它返回QFontMetrics对象
下面是实现方法
# 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, 250)
# setting cursor
self.calendar.setCursor(Qt.PointingHandCursor)
# font
font = QFont('Times', 5)
# setting font to the calendar
self.calendar.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.calendar.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:
