In this article we will see how we can set the minimum possible value to the QDoubleSpinBox. By default minimum possible value is 0 for double spin box. i.e user cant enter value less than 0 although we can change this maximum value any time. By changing the minimum value we allow user to enter value which is greater than the minimum value.

In order to do this we will use setMinimum method with the double spin box object.

Syntax : dd_spin.setMinimum(n)

Argument : It takes float 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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating double spin box
        d_spin = QDoubleSpinBox(self)
        # setting geometry to the double spin box
        d_spin.setGeometry(100, 100, 150, 40)
        # setting decimal precision
        # step type
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType
        # adaptive step type
        # setting minimum value
        # creating a label
        label = QLabel("GeeksforGeeks", self)
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)
        # making label multi line
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
