PyQt5 QSpinBox – Checking if it accelerated or not
  • Last Updated : 28 May, 2020

In this article we will see how we can check if the spin box is accelerated or not. 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. By default spin box don’t accelerate although we can make spin box accelerate using setAccelerated method.

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

Syntax : spin_box.isAccelerated()

Argument : It takes no argument

Return : It returns bool



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)
  
        # creating a label
        label = QLabel(self)
  
        # making the label multi line
        label.setWordWrap(True)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 60)
  
        # checking if spin box is accelerated
        check = self.spin.isAccelerated()
  
        # setting text to the label
        label.setText("Accelerated ? : " + str(check))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
