add child item in list view

Hi,
i create list view , i set model to the list like that

Code:

---

listView->setModel( model );

---

i createthe model like that

Code:

---

void MainWindow::createModel()
{
    model = new QStandardItemModel( 0,0,this );
    model->setHorizontalHeaderLabels( QStringList() << "liste" );
   createModelItems();
}
 
void MainWindow::createModelItems()
{
    QStringList choiceList;
	 QStandardItem *pItem;
 
  choiceList << "conf1" << "conf2" << "conf3";
   foreach( QString str, choiceList ){ // parent
        pItem = new QStandardItem( str );
        pItem->setTristate( true );
        model->appendRow( pItem );
  }
 
  }

---

and i added new item like that with signal slot
the sig,al is

Code:

---

void  MainWindow::add(vector3 point)
{
QStandardItem *item=new QStandardItem(QString ("Marker  %0").arg(nb_mark));		
				nb_mark++;
				emit itemAded(item);
}

---

the slot is

Code:

---

void MainWindow::itemAded( QStandardItem *pItem )
{
 
	model->appendRow( pItem );
}

---

but the problem is that it add to me new item and that's not what i want
i want to add the new item as child of an item of the "chois list"

i know that i must add this infiormation in the signal , but how i do that ? have you an idea ?

Do not implement/define signal method. (Qt will define it). Move the code in the signal into slot and remove the signal definition.

List items cannot have child item, you should use Tree (TreeView) if you want to add new items as children.

no i must add it , because it's important and there is another things i must made it in the signal.

if i use treeview i will change à lot the code ?
another thing i see in some exemple thy used listview with child

Code:

---

void MainWindow::createModelItems()
{
    QStringList choiceList, optionList;
 
    choiceList << "Alpha" << "Beta" << "Charlie";
    optionList << "Opt1" << "Opt2" << "Opt3";
 
    QStandardItem *pItem, *cItem;
 
    foreach( QString str, choiceList ){ // parent
        pItem = new QStandardItem( str );
        pItem->setCheckable( true );
        pItem->setTristate( true );
        foreach( QString str, optionList ){ // children
            cItem = new QStandardItem( str );
            cItem->setCheckable( true );
            pItem->appendRow( cItem );
        }
 
        model->appendRow( pItem );
    }
}

The signal still exists, I mean only the signal declaration should be there (class.h), and signal definition/implementation (class.cpp) should not exists. Qt framework creates the implementation for you.

The code snipet is using QStandardItemModel, this model has to set on a QTreeView.
