PyQt5 QLabel – Setting blur radius to the blur effect
In this article we will see how we can set blur radius to 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 setBlurRadius
method.
Syntax : blur_effect.setBlurRadius(n)
Here blur_effect is the QGraphicsBlurEffect objectArgument : It takes float value as argument
Return : It returns None
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) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
