PyQt5 QSpinBox – Checking if there is over line or not

In this article we will see how we can check if there over line to the text of spin box. An over line, overscore, or over bar, is a typographical feature of a horizontal line drawn immediately above the text. By default there is no over line to the text although we can set the over line with the help of setOverline method.

In order to do this we use overline method with the QFont object of the spin box

Syntax : font.overline()

Argument : It takes no argument

Return : It returns bool

Below is the implementation
