Report issue
In this article we will see how we can set the possible value range to the QDoubleSpinBox. By default possible value range lies from 0 to 100 although we can set individually minimum and maximum possible value with the help of setMinimum and setMaximum method respectively. Setting range allow user to enter those values which lie in the given else it will not be entered.
In order to do this we will use setRange method with the double spin box object. Syntax : dd_spin.setRange(m, n) Argument : It takes two float value 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 range to the double spin box
        d_spin.setRange(11.1, 13.4)
        # 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
