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 :
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
def __init__( self ):
super ().__init__()
self .setWindowTitle( "Python " )
self .setGeometry( 100 , 100 , 600 , 400 )
self .UiComponents()
self .show()
def UiComponents( self ):
button = QPushButton( "CLICK" , self )
button.setGeometry( 200 , 150 , 100 , 40 )
button.setStyleSheet( "color : rgba(0, 0, 0, 100)" )
button.clicked.connect( self .clickme)
def clickme( self ):
print ( "pressed" )
App = QApplication(sys.argv)
window = Window()
sys.exit(App. exec ())
