Sub window or child window ?

A terminology question - again.
I am using "MDI" example as my main widget / form.
Looking at usage of "New file" to find out it builds a "Mdichild ".

So what is a difference between "QMdiSubWindow" and "MdiChild" classes?

@AnneRanch Caught by ignoring the details - again,
MdiChild inherits form QTextEdit hence its function is not directly related to MDI.
