In GUI applications there is need of displaying information this done using labels in PyQt5, but sometimes there is also a need of changing the text of the label, in this tutorial we will see how it can be done.
setText()
method is used to change the content of the label.
Syntax : label.setText(Info)
Argument : It takes string as an argument.
Code :
# importing the required libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore
from PyQt5.QtGui import * import sys
class Window(QMainWindow):
def __init__( self ):
super ().__init__()
# informations
info = "info"
new_info = "new info "
# set the title
self .setWindowTitle( "Label" )
# setting the geometry of window
self .setGeometry( 0 , 0 , 400 , 300 )
# creating a label widget
self .label_1 = QLabel(info, self )
# moving position
self .label_1.move( 100 , 100 )
# setting up border
self .label_1.setStyleSheet( "border: 1px solid black;" )
# creating a label widget
self .label_2 = QLabel(info, self )
# moving position
self .label_2.move( 100 , 150 )
# setting up border
self .label_2.setStyleSheet( "border: 1px solid black;" )
# changing the text of label
self .label_2.setText(new_info)
# show all the widgets
self .show()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
