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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
    # 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
