In this article we will see how we can disable the blur effect of the label according to the user instruction such that when user check the radio button blur effect should disappear and when user uncheck the radio button it should appear again. In order to make the blur effect disable and enable we use setEnabled method.
In order to do this we have to do the following : 1. Create a label 2. Create a blur effect object and set it to the label 3. Create a radio button 4. Add action to the radio button 5. Inside the action check if radio button is checked, it checked make blur effect disable 6. Else make color effect enable
Syntax : blur_effect.setEnabled(False) Argument : It takes bool as argument Return : It returns none
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 label
label = QLabel("Label", self )
# setting geometry to the label
label.setGeometry( 200 , 100 , 150 , 60 )
# setting alignment to the label
label.setAlignment(Qt.AlignCenter)
# setting font
label.setFont(QFont( 'Arial' , 15 ))
# setting style sheet of the label
label.setStyleSheet("QLabel"
"{"
"border : 2px solid green;"
"background : lightgreen;"
"}")
# creating a blur effect
self .blur_effect = QGraphicsBlurEffect()
# setting blur radius
self .blur_effect.setBlurRadius( 15 )
# adding blur effect to the label
label.setGraphicsEffect( self .blur_effect)
# creating a radio button
self .button = QRadioButton("Disable blur effect", self )
# setting geometry
self .button.setGeometry( 200 , 200 , 300 , 30 )
# adding action to the button
self .button.clicked.connect( self .do_something)
# action called by the radio button
def do_something( self ):
# radio is checked ?
if self .button.isChecked() = = True :
# making blur effect disable
self .blur_effect.setEnabled( False )
else :
# making blur color effect enable
self .blur_effect.setEnabled( True )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
