PyQt5 QSpinBox – Setting Properties

In this article we will see how we can set properties to 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 a ability to loop the values, developer will add this property so that other developer can see this and get to know about the property.

In order to do this we use setProperty method

Syntax : spin_box.setProperty(property, value)

Argument : It takes two argument one is string and other is integer

Action performed : It add this property to the spin box



Below is the implementation
