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 ())
