I am having sequence problem

[Qt Enthusiast]

Following sthe post https://forum.qt.io/topic/85736/looking-for-a-sample-example-in-which-qtreewidget-at-left-side-qsplitter-and-qstackedwidget-on-right-side/3

One more question regarding the sequnce of displayed children

   QModelIndex tempIdx  = mdl->index(0,0);
    mdl->setData(tempIdx,"Parent1");
    mdl->setData(tempIdx,m_stacked->addWidget(QLabel("A"),Qt::UserRole);
    ////////////////////////////////////////
    ///////////////////////////////////////////
    tempIdx = mdl->index(0,0,tempIdx);
    mdl->setData(tempIdx,"Child1");
    mdl->setData(tempIdx,m_stacked->addWidget(new QTextEdit("Child1",this)),Qt::UserRole);


    mdl->insertRow(0,tempIdx);
    QModelIndex tempIdx = mdl->index(0,0,tempIdx);
    mdl->setData(tempIdx,"ChildOfChidl1");
    QTableWidget* tempTable1 = new QTableWidget(2,2,this);
    tempTable1->model()->setData(tempTable1->model()->index(0,0),"ChildOfChild1 Cell 0,0");
    tempTable1->model()->setData(tempTable1->model()->index(1,0),"ChildOfChild1 Cell" ,0");
    mdl->setData(tempIdx,m_stacked->addWidget(tempTable1),Qt::UserRole);

    mdl->insertRow(0,tempIdx);
    QModelIndex tempIdx = mdl->index(0,0,tempIdx);
    mdl->setData(tempIdx,"ChildAOfChidl1");
    QTableWidget* tempTable1 = new QTableWidget(2,2,this);
    tempTable1->model()->setData(tempTable1->model()->index(0,0),"ChildOfChild1 Cell 0,0");
    tempTable1->model()->setData(tempTable1->model()->index(1,0),"ChildOfChild1 Cell" ,0");
    mdl->setData(tempIdx,m_stacked->addWidget(tempTable1),Qt::UserRole);

   mdl->insertRow(0,tempIdx);
    QModelIndex tempIdx = mdl->index(0,0,tempIdx);
    mdl->setData(tempIdx,"ChildBOfChidl1");
    QTableWidget* tempTable1 = new QTableWidget(2,2,this);
    tempTable1->model()->setData(tempTable1->model()->index(0,0),"ChildBOfChild1 Cell 0,0");
    tempTable1->model()->setData(tempTable1->model()->index(1,0),"ChildBOfChild1 Cell" ,0");
    mdl->setData(tempIdx,m_stacked->addWidget(tempTable1),Qt::UserRole);

In my case sequence is a issue ChildBOfChild1 is displayed before ChildAOfChild1 why ?

@Qt-Enthusiast said in I am having sequence problem:

mdl->insertRow(0,tempIdx);
QModelIndex tempIdx = mdl->index(0,0,tempIdx);

1. you are always inserting at position 0
2. you are overwriting/redefine the tempIdx variable multiple times

replace

mdl->insertRow(0,tempIdx);
    QModelIndex tempIdx = mdl->index(0,0,tempIdx);

with

const int rowCnt = mdl->rowCount(tempIdx);
mdl->insertRow(rowCnt ,tempIdx);
tempIdx = mdl->index(rowCnt ,0,tempIdx);

to insert at the bottom instead of at the top
