PyQt5 QSpinBox – Accessing Suffix

In this article we will see how we can access the suffix of the spin box, suffix is the extra text added at the end of the value, it is non editable and permanent. By default there is no suffix set to the spin box although we can set suffix any time with the help of setSuffix method.

In order to do this we will use suffix method.

Syntax : spin_box.suffix()

Argument : It takes no argument

Return : It returns string

Steps for implementation :
1. Create a spin box
2. Set suffix with the help of setSuffix method
3. Create label to show the suffix
4. Get the suffix with the help of suffix method
5. Show suffix through label

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, 150, 40)

        # setting step type
        self.spin.setSuffix(" Number(s)")

        # creating label
        label = QLabel(self)

        # setting geometry to the label
        label.setGeometry(100, 160, 200, 30)

        # getting suffix
        suffix = self.spin.suffix()

        # setting text to the label
        label.setText("Suffix: " + suffix)

# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
