In this article we will see how we can adjust the size of the spin box according to the text in it. Somethings when we create a spin box and its value increases then the text size also increases there for it is required to set the size of spin box such that it covers the whole text ago it didn’t take extra space as well. The text includes the prefix, postfix and the value with its length become maximum.

In order to do this we use adjustSize method.

Syntax : spin_box.adjustSize()

Argument : It takes no argument

Action performed : It changes the size of the spin box according to the text

Below is the implementation




# 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, 250, 40)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # setting range to the spin box
        self.spin.setRange(0, 999999)
  
        # adjusting the size of the spin box
        self.spin.adjustSize()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
