I have an QAbstractItemModel implementation which exposes a tree like structure. I'm using standard QTreeView to display its data. Now, I want to let the user have an option to show/hide and move columns in any manner. The problem is if first column is hidden, decoration of tree (i.e. +s & -s to expand or otherwise the data) is also not shown, and when first column is moved, decoration of tree moves along.
What should I do
