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 ())
