PyQt5 QSpinBox – Making it enabled

In this article we will see how we can make spin box enabled according to the user, disabled spin box is basically spin box which can’t be edited i.e which get disabled and enabled spin box is normal spin box, by default spin box is enabled. In order to make spin box disabled we use setDisabled method.

In order to do so we use setEnabled method.

Syntax : spin_box.setEnabled(bool)

Argument : It takes bool as argument

Return : It returns None



Implementation steps :
1. Create a spin box
2. Create a push button and add action to the push button
3. Inside the action make the spin box disabled
4. Create another push button and add action to it
5. Inside the action make the spin box enabled

Below is the implementation
