What is the difference between a List View and a List Widget?
If I'm converting a Visual Studio List Box in a dialog, which one should I use (View or Widget)?

Isn't the documentation clear enough? http://doc.qt.io/qt-5/qlistwidget.html#details
QListWidget is a convenience class that provides a list view similar to the one supplied by QListView, but with a classic item-based interface for adding and removing items. QListWidget uses an internal model to manage each QListWidgetItem in the list.

Well the ListWidget resembles more how a traditional listbox works.
That said, using a model ( ListView) allows for automatic updates to the model
if the Data in the listbox changes. This can be very handy if the data represented in the
"listbox" is shared/replicated among other widgets.
If you already have such synchronization in place, or the data is not shared,
ListWidget might be the fastest route for conversion.
So I would say it mostly depends on the way the listbox data is used/shared/what it represents. -

Thank you @mrjj for a useful answer, that's the kind of high-level overview answer I was looking for. I'm using a plain, ordinary list box where the items are displayed but not edited by the user.

hi
well if the LB items are not shared with other structures / updated often, i would
go with ListWidget as more changes to the code seems required to take full advantage of having a model.
