"Locking" a QTreeWidget ?

[vkincaid]

Maybe I'm missing something from the documentation but I couldn't find a way to "lock" a QTreeWidget object, meaning no column resizing and no column drag/drop. I tried to overwrite drag*Event and dropEvent with empty bodies but that didn't do it. Would anyone know how to accomplish this?

Thanks a lot!

Take a look at QTreeWidget's base classes (QTreeView & QAbstractItemView ). You can use this code to "lock" column widths :

QTreeWidget * MyTree;
MyTree->header()->setResizeMode ( QHeaderView::Fixed );

QTreeWidget * MyTree;
MyTree->header()->setResizeMode ( QHeaderView::Fixed );

To copy to clipboard, switch view to plain text mode 

And this one to lock drag & drop :

MyTree->setDragDropMode ( QAbstractItemView::NoDragDrop );

MyTree->setDragDropMode ( QAbstractItemView::NoDragDrop );

To copy to clipboard, switch view to plain text mode

I think the author also wants QHeaderView::setMovable(false).

Yes, I forgot that one...
