//the textedit should show up the item value here which i select from right click item on TreeWidget, but i don't know how to get the value

}

You can select the item on to which the user has right-clicked and then change the text. Here's the code

Code:

---

void MyProgram::customContentsMenu( const QPoint &pos )
{
    QTreeWidgetItem *item = ui.treeWidget->itemAt(pos);
    if (!item)
        return;
    ui.treeWidget->setCurrentItem(item);
 
    menu->exec(ui.treeWidget->viewport()->mapToGlobal(pos));
}
 
void MyProgram::RegisterMenu()
{
    QTreeWidgetItem *item = ui.treeWidget->currentItem();
    if(item)
        item->setText("Text that you want");
}
