The QLabel Widget PyQt5 Python

1 - Creation of a QLabelPyQt5

To create labels within a window, PyQt5 offers us the QLabel class. You just have to instantiate this class by adding the parent container as a parameter:
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLabel

app = QApplication(sys.argv)
widget = QWidget()
widget.setGeometry(50,50,320,200)
widget.setWindowTitle("Label Example")

# create a QLabel
qlabel = QLabel(widget)
qlabel.setText("Hello World !")

# define the qlabel dimensions & position
qlabel.setGeometry(50 , 50 , 200 , 50)

widget.show()
sys.exit(app.exec_())

2 - Use a design style for a QLabel

A QLabel object has the setStyleSheet() method which allows you to add a qss (Qt Style Sheet) style:
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLabel

app = QApplication(sys.argv)
widget = QWidget()
widget.setGeometry(50,50,350,200)
widget.setWindowTitle("Label Example")

# create a QLabel
qlabel = QLabel(widget)
qlabel.setText("Hello World !")

# define the qlabel dimensions & position
qlabel.setGeometry(50 , 50 , 250 , 50)

# Use QSS designe
qlabel.setStyleSheet("background: darkblue; border: 2px solid red; color:yellow; font:broadway; font-size:36px;")

widget.show()
sys.exit(app.exec_())

 

 


3 - QLabel PyQt5 according to the object approach

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLabel

class Window(QWidget):
    
    def __init__(self  , window):
        super().__init__()
        self.window = window
        
    # create build method
    def build(self):
        self.window.setWindowTitle("Example of QLabel by OOP approach")
        self.window.setGeometry(100 , 100 , 400 , 200)
        
        # create a QLabel
        myLabel = QLabel(self.window)
        myLabel.setText("Example of QLabel by object approach !")
        myLabel.setGeometry(50 , 50 , 300 , 50)  
            
            
if __name__ == "__main__":
    app = QApplication(sys.argv)
    win = QWidget()
    
    myWin = Window(win)
    myWin.build()
    
    win.show()
    app.exec_()
