How to save the content from a QTreeWidget (tree structure, model) to database

[whitefurrows]

Hi

how can i save and load the items for a QTreeWidget(TreeModel) line by line. My current table looks like this(ListModel):

CREATE TABLE tree
(
	ID integer NOT NULL  PRIMARY KEY AUTOINCREMENT, 
	entries varchar (50) NOT NULL 
);

CREATE TABLE tree
(
	ID integer NOT NULL  PRIMARY KEY AUTOINCREMENT, 
	entries varchar (50) NOT NULL 
);

To copy to clipboard, switch view to plain text mode 

and i load it by

QTreeWidgetItem* item;
for (int i=0; i<allEntries.size(); i++)
{
 	item=new QTreeWidgetItem(ui.treeWidget);
	item->setText(0, allEntries.at(i).getName());
}

QTreeWidgetItem* item;
for (int i=0; i<allEntries.size(); i++)
{
 	item=new QTreeWidgetItem(ui.treeWidget);
	item->setText(0, allEntries.at(i).getName());
}

To copy to clipboard, switch view to plain text mode 

Now i want add a field (index) to my database, and store the the current TreeModel-Index within to add rows under a row. How can i do that?
