In this article we will see how we can get the size increment value of spin box or not. Size increment is used when spin box size is changeable with the main window size. Base size is used to calculate a proper spin box size if the spin box defines sizeIncrement. By default, for a newly-created spin box, this property contains a size with zero width and height. WE can set the size increment value with the help of
Below is the formula for getting new spin box size when main window get bigger.
width = baseSize().width() + i * sizeIncrement().width() height = baseSize().height() + j * sizeIncrement().height() Here i, j are the size increment in the main window
In order to do this we use
sizeIncrement method with the spin box object.
Syntax : spin_box.sizeIncrement()
Argument : It takes no argument
Return : It returns QSize object
Below is the implementation
