PyQt5 – Set minimum window size | setMinimumWidth and setMinimumHeight method

When we create a window, by default the window size is resizable although, we can use setMinimumSize() method to set the minimum size of the window. But what if we want to set minimum length only for width or height only, in order to do so we use setMinimumWidth() method to set minimum width and setMinimumHeight() method to set minimum height. When we use these method other length will be variable i.e there will be no minimum length to it, it can shrinks as much it can.

Syntax :

self.setMinimumWidth(width)
self.setMinimumHeight(height)

Argument : Both takes integer as argument.

Action performed.
setMinimumWidth() sets the minimum width.
setMinimumHeight() sets the minimum height.

Code for setting minimum width :

# 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 width
        self.setMinimumWidth(width)

        # creating a label widget
        self.label_1 = QLabel("Minimum width", 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 :
