In this article we will see how we can make the shadow disappear off the label according to the user. Shadow will be shown and disappear when user make the radio button checked and will appear when radio button is unchecked.
In order to do this we use setEnabled method Syntax : shadow.setEnabled(bool) Argument : It takes bool as argument Return : None
Below is the implementation
Python3
# 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 label
label = QLabel("Label", self )
# setting alignment
label.setAlignment(Qt.AlignCenter)
# setting geometry to the label
label.setGeometry( 200 , 100 , 150 , 60 )
# setting border
label.setStyleSheet("border : 8px solid black")
# creating a QGraphicsDropShadowEffect object
self .shadow = QGraphicsDropShadowEffect()
# setting blur radius
self .shadow.setBlurRadius( 30 )
# setting Xoffset
self .shadow.setOffset( 10 )
# adding shadow to the label
label.setGraphicsEffect( self .shadow)
# creating radio button
self .button = QRadioButton("Hide Shadow", self )
# setting geometry to the radio button
self .button.setGeometry( 200 , 200 , 100 , 40 )
# adding action to the button
self .button.clicked.connect( self .hide_shadow)
def hide_shadow( self ):
if self .button.isChecked():
# making shadow off
self .shadow.setEnabled( False )
else :
# making shadow off
self .shadow.setEnabled( True )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
