During the designing of the GUI (Graphical User Interface) application there is a need to display plain text as information where label is used, but sometimes information text could be large or much smaller and it is difficult to use resize() method so have to auto adjust the size of the label according to the text, in order to do so adjustSize() method can be used.

adjustSize() method will change the size of label according to the length of the text, if the length is less it will decrease the length and height of the widget and vice versa.

Syntax : label.adjustSize()

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("== Normal 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("====== Adjusted label =====", self)
  
        # moving position
        self.label_2.move(100, 150)
  
        # setting up border
        self.label_2.setStyleSheet("border: 1px solid black;")
  
        # adjusting the size of label
        self.label_2.adjustSize()
  
  
        # 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())


Output :
pyqt-adjustSize-label
