PyQt5 QSpinBox - Getting top margin

Last Updated : 19 May, 2020

In this article we will see how we can get the top margin of the spin box, by default it is set to zero although we can change this using setTop method with the margin object of spin box. In order to do this we use margin.top method.

Syntax : margin.top() Here margin is the QMargin object of the spin box Argument : It takes no argument Return : It returns integer

Below is the implementation

Python3 1==

# 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, 999999)

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

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

        # creating label
        label = QLabel(self)

        # setting geometry to the label
        label.setGeometry(100, 200, 200, 70)

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

        # setting content margins
        self.spin.setContentsMargins(1, 2, 2, 1)

        # getting content margins
        margin = self.spin.contentsMargins()

        # getting top margin value
        top = margin.top()

        # setting text to the label
        label.setText("Top Margin = " + str(top))

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

# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())
