PyQt5 QSpinBox – How to get the size hint

In this article we will see how we can get the size hint of the spin box. Size hint is the recommended size for the spin box. Recommended size is related to the layout size if the window size is large and there are few widgets then size hint would be larger than normal.

In order to do this we use sizeHint method with the spin box object.

Syntax : spin_box.sizeHint()

Argument : It takes no argument

Return : It returns QSize object

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 range to the spin box
        self.spin.setRange(0, 9)

        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")

        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")

        # creating a label
        self.label = QLabel(self)

        # making label multi line
        self.label.setWordWrap(True)

        # setting label geometry
        self.label.setGeometry(100, 200, 250, 60)

        # getting the size hint
        value = self.spin.sizeHint()

        # setting text to the label
        self.label.setText("Recommended Size : " + str(value))


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

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

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

Output :
