Well, view's are meant to be used with models and give you the full
control over their behaviour, however it takes more time to understand
all parts. Widgets on the other hand hide a good part of the model-stuff
but allow for much easier setup of simple stuff like showing a small
table of items.

You mean you want to insert multiple new rows at once? no problem,
create a button for that and call the models insertRows() function
(button may be a context menu entry too). As for updates, like setting
all values of a column to a specific value, same thing except this time
you'd have to call the models setData() for each row and the changed
column.

If you want a validator on the input create a custom delegate which
provides a lineedit (or whatever you want there) widget which has a
validator set on it as editing widget.
