PyQt5 QSpinBox – Accessing step type

Last Updated : 06 May, 2020

In this article we will see how we can access the step type of the spin box, there are two types of step types i.e default one which increment value normally and other is adaptive decimal.

In order to do this we will use stepType method

Note : This feature was introduced in Qt 5.12. so lower versions don’t have this feature.

Syntax : spin_box.stepType()

Argument : It takes no argument

Return : It returns QAbstractionSpinBox object but when it printed it shows value 0 or 1

Steps for implementation :
1. Create a spin box
2. Set step type to it with the help of setStepStype method
3. Create label to show the step type
4. Get the step type with the help of stepType method
5. Show type 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 range 
        self.spin.setRange(0, 10000) 
  
        # setting value 
        self.spin.setValue(950) 
  
        # setting step type 
        self.spin.setStepType(QAbstractSpinBox.AdaptiveDecimalStepType) 
  
        # creating label 
        label = QLabel(self) 
  
        # setting geometry to the label 
        label.setGeometry(100, 160, 200, 30) 
  
        # getting single step size 
        step_type = self.spin.stepType() 
  
        # setting text to the label 
        label.setText("Step Type : " + str(step_type)) 
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
