PyQt5 QSpinBox – Resizing it according to value

In this article we will see how we can resize the spin box according to its value. We can set the dimension of the spin box with the help of setGeometry method although it takes position argument as well therefore resizing it is not appropriate. In order to do this we use resize method with the spin box object.

Syntax : spin_box.resize(width, height) Argument : It takes two integer as argument Return : It returns None

Below is the implementation 

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)

        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 50, 50)

        # setting range to the spin box
        self.spin.setRange(50, 400)

        # adding action to the spin box
        self.spin.valueChanged.connect(self.spin_action)

    def spin_action(self):

        # getting the value of spin box
        value = self.spin.value()

        # resizing the spin box
        self.spin.resize(value, value)



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
