In this article we will see how we can get the preferred height of the spin box according to the width. Height depending on the width means that when ever the width changes height also changes. By default height don’t depends on the width.

In order to do this we use
heightForWidth method with the spin box object.
Syntax : spin_box.heightForWidth(width)
Argument : It takes integer as argument
Return : It returns integer
Below is the implementation
