QTreeWidget how to's

[bruccutler]

I'm starting to put together a tree control. I need to know if I can use the same pointer to allocate the tree nodes, or if I need to keep separate variables around for each tree node?

Example:

if (pConn)
  {
    while (pConn[i].name != NULL)
    {
      QTreeWidgetItem *subItem = new QTreeWidgetItem(m_pConnectionsItem, ITEM_CONNECTIONS);
      subItem->setText(pConn[i].name);
      i++;
    }
  }

if (pConn)
  {
    while (pConn[i].name != NULL)
    {
      QTreeWidgetItem *subItem = new QTreeWidgetItem(m_pConnectionsItem, ITEM_CONNECTIONS);
      subItem->setText(pConn[i].name);
      i++;
    }
  }

Do I need separate subItems, one for each sub-item in the tree? What is the right way to do this? Does someone have some sample working code I could look at?
