PyQt5 – lower() method for Labels

In PyQt5, when we create more than one label at same position they overlap each other such that the label which was made at last should be shown at top. Although, we can set the opaque level but sometimes some label have lower priority and that’s why they should be at below level therefore, lower() method is used.

Syntax : label.lower()

Argument : It takes no argument.

Action performed : It sets lower priority to the label.

Code :

# importing the required libraries 
  
from PyQt5.QtCore import * 
from PyQt5.QtGui import * 
from PyQt5.QtWidgets import * 
import sys 
  
  
class Window(QMainWindow): 
    def __init__(self): 
        super().__init__() 
  
  
        # set the title 
        self.setWindowTitle("Python") 
  
        # setting geometry 
        self.setGeometry(100, 100, 600, 400) 
  
        # creating a label widget 
        self.label_1 = QLabel("old label ", self) 
  
        # setting up the border and background color 
        self.label_1.setStyleSheet("border :3px solid black;  
                                    background : pink") 
  
        # moving the label 
        self.label_1.move(100, 100) 
  
        # creating a new label widget 
        self.label_2 = QLabel("new Label ", self) 
  
        # setting up the border and background color 
        self.label_2.setStyleSheet("border :3px solid black; 
                                    background : green") 
  
        # setting lower priority to this label 
        self.label_2.lower() 
  
        # moving the label 
        self.label_2.move(110, 110) 
  
  
        # show all the widgets 
        self.update() 
        self.show() 
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
