PyQt5 QSpinBox – Getting property value

In this article we will see how we can get the property value of the spin box, properties are the information added by the developer to tell about the properties of the spin box, for example, if spin box has ability to loop the values, the developer will add this property so that other developer can see this and get to know about the property. Properties are added using setProperty method.

In order to do this we use property method

Syntax : spin_box.property(property)

Argument : It takes string as argument

Return : It returns integer

Below is the implementation

# importing libraries

from PyQt5 import QtCore, QtGui

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")

        # adding property to the spin box
        self.spin.setProperty("Dynamic", 1)

        # adding property to the spin box
        self.spin.setProperty("Has suffix", 1)

        # creating label
        self.label = QLabel(self)

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

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

        # property
        property_name = "Dynamic"

        # getting property value
        value = self.spin.property(property_name)

        # setting text to the label
        self.label.setText("Property Name :  " + property_name +
                           "  Property Value : " + str(value))

# 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())

Output :
