InsertChild does not its work (solved)
-
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.
Anyone can help me please? Thanks!

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:
bq. If the child has already been inserted somewhere else it won't be inserted again.
I hope I could help someone. Enjoy Qt!
