How to add a branch to a QTreeView? Add child branch?

Answer 1

Like this:

QTreeWidgetItem* top_level = new QTreeWidgetItem(m_three);

QTreeWidgetItem* child_item = new QTreeWidgetItem(top_level);

Or:

QStandardItemModel model(rows, columns);

QStandardItem *item = new QStandardItem("top");
QStandardItem *child = new QStandardItem("child");

model.setItem(row, column, item);
