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): 
        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, 300, 70) 
  
        # making it multi line label 
        self.label.setWordWrap(True) 
  
        # getting property names 
        p_names = self.spin.dynamicPropertyNames() 
  
        # setting text to the label 
        self.label.setText(str(p_names)) 
  
# 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())
