[Qt-interest] how to prevent selecting multiple columns in a QTableView

[Andy Hirsh]

Hello Samuel

  mmm... maybe I'm doing something wrong, but I was not able to set this
behaviour using the two functions you talk about; what I need is to allow
multiple item selection, but only if they are on the same column.

note that setting:

   tableView->setSelectionBehavior(QAbstractItemView::SelectColumns);

will select always the entire column, while I want to be able to select only
part of it...

  thanks a lot for your help

          Andy
