PyQt5 – Create translucent Push Button

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())

Output :
