In this article we will see how we can access the blur radius of the label blur effect. The blur radius (required), if set to 0 the shadow will be sharp, the higher the number, the more blurred it will be. By default the blur radius value is 5.0 we can change it any time.
In order to do this we use blurRadius method.
Syntax : blur_effect.blurRadius()
Here blur_effect is the QGraphicsBlurEffect object
Argument : It takes no argument
Return : It returns float value
Below is the implementation
Python3
# 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 )
# getting blur radius
b_radius = self .blur_effect.blurRadius()
# setting text to the result
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 ())
