PyQt5 QSpinBox – Making it accelerate

In this article we will see how we can make the spin box accelerate. Accelerating the spin box means to speed up the frequency of the steps when pressing the step Up/Down buttons. If spin box is set to accelerate then it will increase/decrease the value faster the longer you hold the button down.

In order to do this we use setAccelerated method with the spin box object.

Syntax : spin_box.setAccelerated(True)

Argument : It takes bool as argument

Return : It returns 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, 250, 40)

        # setting range to the spin box
        self.spin.setRange(1, 999999)

        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")

        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")

        # making spin box accelerate
        self.spin.setAccelerated(True)


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

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

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

Output :
