In this article we will see how we can check if the blur effect of the label is disabled or not, by default there is no blur effect to the label although we can add blur effect any time. In order to make blur effect enable or disable we use setEnable method. In order to check the blur effect is disable and enable we use isEnabled method.
Syntax : blur_effect.isEnabled() Argument : It takes no argument Return : It returns bool
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 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 result label
result = QLabel( self )
# setting geometry to the result
result.setGeometry( 200 , 200 , 300 , 30 )
# checking if blur effect is enabled or not
check = self .blur_effect.isEnabled()
# setting text to the result
result.setText("Blur 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 ())
