Drag n Drop for QTableView objects
Message 1 in thread
Hi,
I have a few apps that I'm converting to Qt4, and I've come across a few
problems using the new QtableView classes. One problem I haven't been
able to solve is getting column headers to respond to drag n drop
events. I want to be able to move columns to a different position or
remove them by dragging them out. I have found a Qt help file containg a
chapter about Using Drag and Drop with Item Views, but it only mentions
MIME copies and nothing about whole columns. Does anybody knoe how to
achieve this with the new QtableView classes.

P.S. I'm using Qt4.2, winxpsp2.

For moving them around by D&D, you can use QHeaderView::setMovable.
Dragging them out of the header won't be that easy, but migth work as
well... somehow. We let the user remove columns by popping up a context
menu on the header that allows you to toggle display of columns (or rows).
