PyQt5 QSpinBox – 获取字间距

在本文中，我们将了解如何获取旋转框文本中的单词间距。单词是由其他字母用空格分隔的单个字母组，单词间距会增加它们之间的空间。我们可以借助setWordSpacing方法设置字间距。

注意：将间距设置为较低的值不能减小间距。

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

Syntax : font.wordSpacing()

Argument : It takes no argument

Return : It returns float

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(" one two")
  
        # getting font of the spin box
        font = self.spin.font()
  
        # setting word spacing
        font.setWordSpacing(20)
  
        # 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 word spacing
        check = font.wordSpacing()
  
        # setting text to the label
        label.setText("Word Spacing : " + str(check))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
