PyQt5 Label – Checking if shadow is widget type

0 1 1 minute read

In this article we will see how we can check if the label shadow is widget type. Widget type is the property that tells if the object is widget or not.

In order to do this we use isWidgetType method

Syntax : shadow.isWidgetType()

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 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) 
  
        # adding shadow to the label 
        label.setGraphicsEffect(self.shadow) 
  
        # checking if shadow is widget type 
        check = self.shadow.isWidgetType() 
  
        # making label 
        result = QLabel(self) 
  
        # setting geometry 
        result.setGeometry(200, 200, 300, 30) 
  
        # setting text 
        result.setText("Widget 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())
