PyQt5 QSpinBox - 设置固定间距

在本文中，我们将了解如何使用系统字体为旋转框创建等宽字体（固定间距），等宽字体，也称为固定间距、固定宽度或非比例字体, 是一种字体，其字母和字符各自占据相同数量的水平空间。这与可变宽度字体形成对比，其中字母和间距具有不同的宽度。我们可以借助font方法获得旋转框的 QFont 对象。

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

Syntax : font.setFixedPitch(True)

Argument : It takes bool 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')
  
        # making font mono-spaced
        font.setFixedPitch(True)
  
        # 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 ：
