PyQt5 QSpinBox – 设置字距

在本文中,我们将了解如何设置或禁用旋转框文本的字距调整。在排版中,字距调整是按比例字体调整字符间距的过程,通常是为了获得视觉上令人愉悦的结果。字距调整单个字母形式之间的间距,而跟踪则在一系列字符上均匀地调整间距。默认情况下,此属性为 True。

下面是字距调整效果的表示

为了做到这一点,我们使用setKerning方法和旋转框的 QFont 对象

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 = self.spin.font()
  
        # disabling the kerning effect
        font.setKerning(False)
  
        # reassigning 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())
