PyQt5 – How to change the text of existing push button ?
  • Last Updated : 22 Apr, 2020

In this article we will see how to change the text of existing push button. We know when we create a button, we set the text to it but sometimes, conditions occur in which re-usability of push button occur i.e button should do its normal operation just change the text of it, so it look different.

In order to do this we use setText method. This method will over-write the existing text of push button.

Syntax : button.setText(new_text)

Argument : It takes string as argument.

Action performed : It over-write the text of 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, 30)
  
        # adding action to a button
        button.clicked.connect(self.clickme)
  
        # changing the text of button
        button.setText("Over-write")
  
  
    # 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())
