Description
Following step by step the Editable Tree Model Example (https://doc.qt.io/qt-5/qtwidgets-itemviews-editabletreemodel-example.html) leads to an incomplete result. While the TreeItem class is mostly complete (only missing the explanation for its removeColumns method), the TreeModel itself is almost entirely omitted. It's basically missing explanations for the following:
QVariant TreeModel::data(const QModelIndex &index, int role) const QVariant TreeModel::headerData(int section, Qt::Orientation orientation, int role) const bool TreeModel::insertColumns(int position, int columns, const QModelIndex &parent) bool TreeModel::insertRows(int position, int rows, const QModelIndex &parent) bool TreeModel::removeColumns(int position, int columns, const QModelIndex &parent) bool TreeModel::removeRows(int position, int rows, const QModelIndex &parent) bool TreeModel::setData(const QModelIndex &index, const QVariant &value, int role) bool TreeModel::setHeaderData(int section, Qt::Orientation orientation, const QVariant &value, int role) void TreeModel::setupModelData(const QStringList &lines, TreeItem *parent)
The main window code is also entirely omitted.
I'm very well aware that the example is already huge and complex, but reaching the end after an hour and realizing that you actually don't have half what you need to understand the whole picture is pretty unsettling.
