PyQt5 QCommandLinkButton – Setting Graphics Effects

  • Last Updated : 30 Jun, 2020
Geek Week

In this article we will see how we can set graphic effect to the QCommandLinkButton. Graphic effect can be shadow, blur or color effect, these effect can be changed any time also new effects can be created any time. If there already is an effect installed on this command link button, QWidget will delete the existing effect before installing the new effect.

In order to do this we use setGraphicsEffect method with the command link button object

Syntax : button.setGraphicsEffect(effect)

Argument : It takes QGraphicEffect object as argument

Return : It returns None



Note: This method will apply the effect on itself and all its children.

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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating a command link button
        cl_button = QCommandLinkButton("Press", self)
  
        # setting geometry
        cl_button.setGeometry(250, 100, 200, 50)
  
        # shadow effect
        effect = QGraphicsDropShadowEffect()
        effect.setOffset(20, 20)
  
        # setting effect to the command link button
        cl_button.setGraphicsEffect(effect)
  
          
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
