QTreeWidgetItem::insertChild does not its work

I have a QTreeWidget and I would like to insert a child at a certain index. I tried with

void QTreeWidgetItem::insertChild ( int index, QTreeWidgetItem * child )

but any index I put, it inserts the child at the end of all children the parent has.

I found the solution:

My first code was this

QTreeWidgetItem* newVtxItem = new QTreeWidgetItem(parentItem);
newVtxItem->setText(0, "vtx 1");
newVtxItem->setText(1, "-1");
childOfNameProfile->insertChild(0,newVtxItem);

Then I correct it by deleting the parentItem of the new QTreeWidgetItem in this way:

QTreeWidgetItem* newVtxItem = new QTreeWidgetItem();
newVtxItem->setText(0, "vtx 1");
newVtxItem->setText(1, "-1");
childOfNameProfile->insertChild(0,newVtxItem);

The reason why the child was inserted after all children is because when you create a QTreeWidgetItem and defining a parent, Qt put it directly at the end of the children list of the parent. So insertChild, as the documentation said:

If the child has already been inserted somewhere else it won’t be inserted again.

I hope I could help someone. Enjoy Qt!
