Sometimes it is even desirable to have the signal private. This is the case for example in QAbstractItemModel, where otherwise, developers tend to emit signal from the derived class which is not what the API wants. There used to be a pre-processor trick that made signals private but it broke the new connection syntax.

QTreeView and QAbstractItemModel I'm new to Qt and I'm trying to make a simple tree based on a flat (or from a sqlite table) I looked into QAbstractItemModel but I have some difficulties to build the tree.
It turns out the sort method in QAbstractItemModel is not implemented. So I had to implement it myself. Hence, my previous post, How to sort a table by columns in Python. I'm not sure if this is the best way to implement the sort method, but I couldn't find anything else out there, and this seems to work for me.
bool QAbstractItemModel:: insertColumn (int column, const QModelIndex & parent = QModelIndex()) Inserts a single column before the given column in the child items of the parent specified. Returns true if the column is inserted; otherwise returns false. See also insertColumns(), insertRow(), and removeColumn().
