If you need columns in your list, then you should use table (not list), list is always one column.

Start exploring use of QTableView

You get that error because there is no c-tor like you which there were. Further it is more a table than a list you are creating. Have a look at QStandardItemModel and the first example in the detailed description is what you are looking for.

You can also fix your code:

QStandardItemModel *listmodel = new  QStandardItemModel(this);
    QStandardItem * root = listmodel->invisibleRootItem();
    QList<QStandardItem *> row;
    row << new QStandardItem("col1")  << new QStandardItem("col2")  << new QStandardItem("col3") ;
    root->appendRow(row);

QStandardItemModel *listmodel = new  QStandardItemModel(this);
    QStandardItem * root = listmodel->invisibleRootItem();
    QList<QStandardItem *> row;
    row << new QStandardItem("col1")  << new QStandardItem("col2")  << new QStandardItem("col3") ;
    root->appendRow(row);
