In this article we will see how we can dump the object tree of the spin box, dumping object tree means to dump a tree of children to the debug output. Object tree is a tree data structure holding child objects of spin box at the nodes.
In order to do this we use dumpObjectTree method
Syntax : spin_box.dumpObjectTree()
Argument : It takes no argument
Return : It returns None
Note: Before Qt 5.9, this function was not constant function.
