can't do a QTreeView with a QStandardItemModel

[wysota]

Maybe you also need to insertColumns() ?

no because I do it before. My problem is I don't see the children indexB but I can see the parents indexA and indexC.

Any others idea?

no because I do it before.

Are you sure you did that with "indexA" as a parent too?

Try:

m_model->insertRows(0,1,indexA);
m_model->insertColumns(0,1,indexA);
QModelIndex indexB = m_model->index(0, 0, indexA);
m_model->setData(indexB, "jaja");

m_model->insertRows(0,1,indexA);
m_model->insertColumns(0,1,indexA);
QModelIndex indexB = m_model->index(0, 0, indexA);
m_model->setData(indexB, "jaja");
