PyQt5 QSpinBox – Setting range

In this article we will see how we can set range to the spin box, by default when we create a spin box it range varies from 0 to 99 i.e minimum value(lower bound) is 0 and maximum value(maximum bound) is 99 although we can change this range.

In order to do this we will use setRange method.

Syntax : spin_box.setRange(min_value, max_value)

Argument : It takes two integer i.e minimum and maximum value as argument

Return : None

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 range
        self.spin.setRange(-1, 1)


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

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

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

Output :
