Which Class should inherit a QMainWindow? : <p>I am new to Qt and this is probably a very stupid question. I am working on a Project with several sub-projects in Visual Studio (C++). The whole project has a single User-interface (UI), and for that, the Qt is used. </p>

<p>Among all the sub-projects, only 2 classes are inherited from QMainWindow.</p>

<p>As a newbie, I am wondering, which classes should inherit QMainWindow?</p>
