0.) QTextBrowser is an actual light-weight browser with limited HTML 
support of a sub-set of HTML 4, but it is good enough for many tasks - 
especially when the HTML is generated inside the program itself and 
displays only relatively simple content. It can be used for 
documentation, if you can live without complex CSS. It is not good 
enough to display external web pages.

1.) QtWebView is not exactly light-weight. For Windows and Linux it uses 
QtWebEngine for rendering, on Apple OSes it uses the system browser 
engine (derived from the same code base as WebEngine).

Use this if you want to be compatible with all platforms, since e.g. the 
iOS app store forbids you to use your own browser component and forces 
the use of the system component.

2.) No idea, never used it. Hopefully someone else will answer that.

3.) Correct.

4.) See above. And you can always call QDesktopServices::openUrl to open 
the system browser.
