In this article we will see how we can add shadow to the label by default there is no shadow to the label although we can create shadow to the label, below is the representation of how label with shadow box looks like

In order to do this we have to do the following –

1. Create a label
2. Set geometry to the label
3. Create a QGraphicsDropShadowEffect object
4. Set blur radius to the object(optional)
5. Add this object to the label with the help of setGraphicsEffect method

Syntax :

# creating a QGraphicsDropShadowEffect object
shadow = QGraphicsDropShadowEffect()

# setting blur radius (optional step)
shadow.setBlurRadius(15)

# adding shadow to the label
label.setGraphicsEffect(shadow)

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 background color of window
        # self.setStyleSheet("background-color : black;")
  
        # 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, 150, 200, 80)
  
        # setting border
        label.setStyleSheet("border : 10px solid black")
  
        # creating a QGraphicsDropShadowEffect object
        shadow = QGraphicsDropShadowEffect()
  
        # setting blur radius
        shadow.setBlurRadius(15)
  
        # adding shadow to the label
        label.setGraphicsEffect(shadow)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
