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 :
