title: Qt - what's preferred to use - widgets or views? (Tree, Table, List)
body: <p>I started to use Qt model-view system with QStandardItemModel and some views. But then I noticed that there are also Widgets - Tree, Table, List, that happend to be almost the same in use as views. I read Qt docs <a href="http://qt-project.org/doc/qt-4.8/model-view-programming.html" rel="noreferrer">about it</a> and honesty didn't understand for what we need also widgets, why  views is not sufficient..</p>
