PyQt5 – How to clear the content of label | clear and setText method
In this article, we will see how we can easily clear/erase the content of the label of PyQt5 application. This can be done in two ways –
- Using
clear()method, this will clear the content of the label. - Using
setText()method with passing a blank string, this will update the content with blank string.
Using clear() method –
Syntax : label.clear()
Argument : It takes no 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__() # 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("Label", 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("Hidden Label", self) # moving position self.label_2.move(100, 150) # setting up border self.label_2.setStyleSheet("border: 1px solid black;") # clearing the data self.label_2.clear() # 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()) |

Using setText() method –
Syntax : label.setText(“”)
Argument : It takes string as argument, here string will be blank.
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__() # 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("Label", 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("Hidden Label", self) # moving position self.label_2.move(100, 150) # setting up border self.label_2.setStyleSheet("border: 1px solid black;") # replacing content with blank self.label_2.setText("") # 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()) |
