PyQt5 QSpinBox – Checking if Auto Fill Background property is enabled or not

Last Updated : 17 May, 2020

In this article we will see how we can see if the auto fill property of the spin box is enabled or not, this property will cause Qt to fill the background of the spin box before invoking the paint event. The color used is defined by the QPalette.Window color role from the spin box’s palette. By default this property is false although we can change this using setAutoFillBackground method.

In order to do this we use autoFillBackground method.

Syntax : spin_box.autoFillBackground()

Argument : It takes no argument

Return : It returns bool

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, 250, 40) 
  
        # setting prefix to spin 
        self.spin.setPrefix("Prefix ") 
  
        # setting suffix to spin 
        self.spin.setSuffix(" Suffix") 
  
        # creating a label 
        label = QLabel(self) 
  
        # setting geometry to the label 
        label.setGeometry(100, 200, 300, 30) 
  
        # checking if auto fill background is enabled 
        check = self.autoFillBackground() 
  
        # setting text to the label 
        label.setText("Auto Fill Background Enabled ? : " + str(check)) 
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
