PyQt5 – Create translucent Push Button

Last Updated : 22 Apr, 2020

In this article we will see how to create translucent button, here translucent refer as button which are not completely opaque.

In order to do this, we have to change the alpha level of push button, alpha level is the opaque factor greater the value of alpha more the object is opaque, but unlike main window we can’t use setWindowOpacity method, therefore in order to change the alpha value we will use setStyleSheet method.

Below is the difference between normal button and translucent button.

Syntax : button.setStyleSheet(“color : rgba(0, 0, 0, 100)”)

Argument : It takes string as argument. Here Rgba refer to red, green, blue and alpha level, they all vary from 0 to 255.

Action performed : It will set the alpha level of push button

Code :

# importing libraries 
from PyQt5.QtWidgets import * 
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 a push button 
        button = QPushButton("CLICK", self) 
  
        # setting geometry of button 
        button.setGeometry(200, 150, 100, 40) 
  
        # setting alpha level 
        button.setStyleSheet("color : rgba(0, 0, 0, 100)") 
  
        # adding action to a button 
        button.clicked.connect(self.clickme) 
  
    # action method 
    def clickme(self): 
  
  
        # printing pressed 
        print("pressed") 
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
