How to get a child of rootIndex() in QTreeView ?
-
I want to get all top level items in my tree view to make a loop. I do next:
@QModelIndex root(rootIndex());int row = 0; QModelIndex sessionIndex = root.child(row,SessionsTreeModel::eName); while (sessionIndex.isValid()) { sessionIndex = sessionIndex.sibling(row,SessionsTreeModel::eName); int id = m_model->data(sessionIndex,Qt::UserRole).toInt(); if (sessionID == id) { m_model->removeSession(sessionIndex.row()); update(); return; } row++; }@
But my sessionIndex always invalid. I find next in Qt Assistant : bq. QModelIndex QModelIndex::child ( int row, int column ) const
Returns the child of the model index that is stored in the given row and column.
Note: This function does not work for an invalid model index which is often used as the root index. bq.
So how can I get child of rootIndex ?
