PyQt5 QSpinBox – Getting letter spacing type

  • Last Updated : 22 May, 2020

In this article we will see how we can get the letter spacing type of the text of spin box, letter spacing is the distance(gap) in-between two consecutive letter. Spacing can be change by specifying the pixels or the percentage. In order to set the spacing we use setLetterSpacing method with the QFont object of the spin box.

Letter spacing is of two types first is the PercentageSpacing which is default and its value is 0, it set the value by accepting the value in percentage for 0 pixel percentage value is 100. And the other type is AbsoluteSpacing its value is 1, it sets value by accepting the value in pixels.

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

Syntax : font.letterSpacingType()

Argument : It takes no argument



Return : It returns type of spacing, when it get printed it shows only the type value

Below is the implementation




# 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 type
        space_type = font.letterSpacingType()
  
        # setting text to the label
        label.setText("Spacing type : " + str(space_type))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
