PyQt5 QSpinBox – Getting all the properties names

  • Last Updated : 19 May, 2020

In this article we will see how we can get all the properties name of the spin box that are added dynamically to it, 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, 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 dynamicPropertyNames method

Syntax : spin_box.dynamicPropertyNames()

Argument : It takes no argument

Return : It returns list

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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
        # 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, 300, 70)
        # making it multi line label
        # getting property names
        p_names = self.spin.dynamicPropertyNames()
        # setting text to the label
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
