In this article we will see how we can access the blur radius of the shadow of the label. The blur radius, if set to 0 the shadow will be sharp, the higher the number, the more blurred it will be, by default the blur radius is 0, we use setBlurRadius
method to set the blur radius
In order to access the blur radius of the shadow of label we use
blurRadius
methodSyntax : shadow.blurRadius(n)
Here shadow is the QGraphicsDropShadowEffect objectArgument : It takes no argument
Return : It returns float value
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 , 100 , 150 , 60 )
# setting border
label.setStyleSheet( "border : 8px solid black" )
# creating a QGraphicsDropShadowEffect object
shadow = QGraphicsDropShadowEffect()
# setting blur radius
shadow.setBlurRadius( 15 )
# adding shadow to the label
label.setGraphicsEffect(shadow)
# creating label to show the blur radius
result = QLabel( self )
# setting geometry
result.setGeometry( 200 , 200 , 200 , 30 )
# getting blur radius
b_radius = shadow.blurRadius()
# showing text through label
result.setText( "Blur Radius : " + str (b_radius))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
