PyQt5 QSpinBox – 设置家族名称

在本文中，我们将看到如何将姓氏设置为旋转框的字体。家族名称还可以可选地包括铸造厂名称，例如“Helvetica [Cronyx]”。如果该系列可从多个代工厂获得且未指定代工厂，则选择任意代工厂。如果系列不可用，将使用字体匹配算法设置系列。

In order to do this we setFamily method with the QFont object of the spin box

Syntax : font.setFamily(name)

Argument : It takes string as argument

Return : It returns None

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
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting range to the spin box
        self.spin.setRange(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
  
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
  
        # getting font of the spin box
        font = QFont('Arial')
  
        # setting font family name
        font.setFamily("Spin box font_family")
  
        # setting back this font to the spin box
        self.spin.setFont(font)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
