PyQt5 – Checking if the blur effect is disabled or not

0 0 1 minute read

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

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())
