PyQt5 QSpinBox – Setting Minimum value

0 0 1 minute read

In this article we will see how we can set the minimum value i.e lower bound of the spin box, by default when we create a spin box it ranges from 0 to 99 i.e its minimum value is 0 although we can change this.

In order to do this we will use spin_box.setMinimum method.

Syntax : spin_box.setMinimum(n)

Argument : It takes integer 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, 100, 40) 
  
        # setting minimum value 
        self.spin.setMinimum(-10) 
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
