QTreeView::setFirstColumnSpanned() for all attached views of a model

[tgru]

The user can insert an item in a QAbstractItemModel (beginInsertRows and so on). Now I would like to call setFirstColumnSpanned() on all attached views (depending on some type of inserted item).

How can I run some code on all attached views or is there some different approach?

Thank you!
Thomas

There's no need to do anything that radical.

Ok, this one is working.
But what about
https://bugreports.qt-project.org/browse/QTBUG-31384
This is happening in my case too.

Thanks again,
