PyQt5 QSpinBox – 获取字母间距

在本文中，我们将了解如何获取旋转框文本中的字母间距，字母间距是两个连续字母之间的距离（间隙）。可以通过指定像素或百分比来更改间距。为了设置间距，我们使用带有旋转框的 QFont 对象的setLetterSpacing方法。

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

Syntax : font.letterSpacing()

Argument : It takes no argument

Return : It returns floating value

注意：返回值不知道该值是百分比还是百分比

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()
  
        # setting letter spacing
        font.setLetterSpacing(QFont.AbsoluteSpacing, 8)
  
        # reassigning this font to the spin box
        self.spin.setFont(font)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
  
        # getting letter spacing in between the text
        space = font.letterSpacing()
  
        # setting text to the label
        label.setText("Spacing Size : " + str(space))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
