You seem to be confused about the type of model you want to use. Do you want to have one item per row, or do you need columns? If you need columns (and it looks like you do), then QStringListModel isn't suitable for your purpose.

I found the error my self now data display in listview but my expected out put is not in there after one item display in listview there are huge gap between first and second items in listview any body have better idea about that.

my current code

@ model2 = new QStandardItemModel();

QFile file(" file name");
file.open(QIODevice::ReadOnly | QIODevice::Text);

QTextStream in(&file);
while(!in.atEnd()){
QString line = in.readLine();

QList<QStandardItem *> items;
QStringList fields = line.split(">");

QStringList fields3 = fields.filter("#");

foreach (QString text, fields3)
items.append(new QStandardItem((QString)text));

model2->appendRow(items);

}
ui.listView->setModel(model2); @

Hi,

You don't check for empty strings when appending items, you might be seeing a result from that.

Thank you all problem was solved i got my expected output

@

model2 = new QStandardItemModel();

QFile file("file name ");
