In this article we will see how we can check if the blur effect of the label is window type or not. Window type allows user to know if blur effect object is window type just like main window, pop-up etc or not.

In order to check the blur effect is window type or not we use isWindowType method.

Syntax : blur_effect.isWindowType()

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 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 window type
        check = self.blur_effect.isWindowType()
  
        # setting text to the result
        result.setText("Window type ? : " + str(check))
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
