In this article, we will see how to stop resizing of the main window. While making a window, we get options like going full screen and using cursor to change its size. By using setFizedSize() method we can prevent the resizing of the image.

Syntax : self.setFixedSize(width, height)

Argument : It takes two integer as argument i.e width and height.

Action performed : It set the fixed size of window.

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")
  
        width = 500
        height = 400
        # setting  the fixed size of window
        self.setFixedSize(width, height)
  
        # creating a label widget
        self.label_1 = QLabel("Fixed size window", self)
  
        # moving position
        self.label_1.move(100, 100)
  
        # setting up the border
        self.label_1.setStyleSheet("border :3px solid black;")
  
        # resizing label
        self.label_1.resize(120, 80)
  
        # 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-stop-resize-window
