    void MyTreeWidget::createChild()
    {
    QTreeWidgetItem* new_child = new QTreeWidgetItem();
    new_child->setText(0,"Untitled Playlist");
    new_child->setFlags(new_child->flags() | Qt::ItemIsEditable);
    topLevelItem(1)->insertChild(0,new_child);
    editItem(new_child);
    }
    after this function executes, the new_child should be edited now
    but when i use qDebug() to it, it outputs "Untitled Playlist"

        Hi,

        Where are you calling that qDebug ?

          hello,
          here

          void MyTreeWidget::keyPressEvent(QKeyEvent *e)
          {
          if ( ( e->key() == Qt::Key_Return || e->key() == Qt::Key_Enter ) && !hasFocus() )
          {

              qDebug() << topLevelItem(1)->child(0)->text(0);
              emit newChildCreated(topLevelItem(1)->child(0)->text(0)); // this one has nothing to do with tree
          

          }

            You might be getting the value before it has been transferred to the model
