PyQt5 QDoubleSpinBox – Getting Maximum Possible Value

Last Updated : 28 Jul, 2020

In this article we will see how we can get the maximum possible value to the QDoubleSpinBox. By default maximum possible value is <100 for double spin box. i.e user cant enter value greater or equal to the 100 although we can change this maximum value any time with the help of setMaximum method. By changing the maximum value we allow user to enter value which is less than the maximum value.

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

Syntax : dd_spin.maximum()

Argument : It takes no argument

Return : It returns float

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, 500, 400) 
  
        # calling method 
        self.UiComponents() 
  
        # showing all the widgets 
        self.show() 
  
    # 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 
        d_spin.setDecimals(1) 
  
        # step type 
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType 
  
        # adaptive step type 
        d_spin.setStepType(step_type) 
  
        # setting maximum value 
        d_spin.setMaximum(9.9) 
          
        # creating a label 
        label = QLabel("GeeksforGeeks", self) 
  
        # setting geometry to the label 
        label.setGeometry(100, 200, 300, 80) 
  
        # making label multi line 
        label.setWordWrap(True) 
  
        # getting maximum value 
        value = d_spin.maximum() 
  
        # setting text to the label 
        label.setText("Max Possible Value : " + str(value)) 
  
  
  
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
