What is the "main widget" in QT?

I've seen the main widget referenced in a few QT docs. Does this simply refer to the first widget created after QApplication?

If so, is it automatically the widget to which all user events are sent by default?

If not, could you explain what i'm missing?

They probably refer to the QMainWindow class.

In Qt, any parentless widget is a top-level window by default. Any widget type could be your "main" window. You can have more than one. It's a convention, not a technicality.

QMainWindow incorporates a lot of common features and I recommend you start there unless you want something unusual.

The mainWidget is a Qt 3 relic, and is no longer actively supported. Its Qt 4 counterpart is the QMainWindow class.
