We know that we can resize the window of PyQt5 application, but while shrinking the window size we can set minimum size so that it can’t be shrank any more. In this article, we will see how to do this.

In order to do this we will use setMinimumSize() method.

Syntax : self.setMinimumSize(width, height)

Argument : It takes two integer as argument.

Action performed : It sets the minimum 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 = 200
        height = 200
  
        # setting the minimum size
        self.setMinimumSize(width, height)
          
        # creating a label widget
        self.label_1 = QLabel("Minimum size", self)
  
        # moving position
        self.label_1.move(0, 0)
  
        # 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-setMinimumSize-window
