QTreeWidget两次添加相同的项目

Question

I'm trying to make some kind of recursion. If you open P then you can open P again or do something else. And here is my problem:
I can't add same item twice.

while (*it) {
    if ((*it)->text(0) == item->text(0)){
        (*it)->setText(0,"Add_item");
        (*it)->addChild(item);
    }
}

Can I make a loop in QTree ?

Answer 1

You need to create another item. It seems you add for the same text the same item object over and over again as child. So making a copy of the item and adding that copy as child should work.
