QTreeView PARENT & CHILD

[zeeb100]

hi i do this code:

QItemSelectionModel *sel=dirv->treeView->selectionModel();
 
QModelIndexList modelindex;
 
QVariant data;
 
QAbstractItemModel *am=dirv->treeView->model();
 
modelindex=sel->selectedIndexes();
 
int i=0;
 
QList<QModelIndex> index(modelindex);
 
for(i=0; i<index.size();++i){
        QModelIndex mi=index.at(i);
        QVariant data=am->data(mi,0);
 
        QString s = data.toString();
        QByteArray bytArr = s.toLatin1();
        char *pr = bytArr.data();
 
        QModelIndex mi2= index.at(1).parent();
        QVariant data2=am->data(mi2,0);
        QString s2 = data2.toString();
        QByteArray bytArr2 = s2.toLatin1();
        char *pr2 = bytArr2.data();
 
        cout << i << "child:::" << pr << "---parent:::" << pr2 << endl;
    }

QItemSelectionModel *sel=dirv->treeView->selectionModel();

QModelIndexList modelindex;

QVariant data;

QAbstractItemModel *am=dirv->treeView->model();

modelindex=sel->selectedIndexes();

int i=0;

QList<QModelIndex> index(modelindex);

for(i=0; i<index.size();++i){
        QModelIndex mi=index.at(i);
        QVariant data=am->data(mi,0);

        QString s = data.toString();
        QByteArray bytArr = s.toLatin1();
        char *pr = bytArr.data();

        QModelIndex mi2= index.at(1).parent();
        QVariant data2=am->data(mi2,0);
        QString s2 = data2.toString();
        QByteArray bytArr2 = s2.toLatin1();
        char *pr2 = bytArr2.data();

        cout << i << "child:::" << pr << "---parent:::" << pr2 << endl;
    }

To copy to clipboard, switch view to plain text mode 

why if i selected 5 different item in different folder
the parent is the first selected item ????????

exemple:
i select
x.jpg ---> image
and
y.jpg ---> img

output:
child:::x.jpg---parent:::image
child:::y.jpg---parent:::image

sorry i'm very tired the error was

QModelIndex mi2= index.at(1).parent();

correct is
QModelIndex mi2= index.at(i).parent();



but after 8 hours on pc..
