QStandardItemModel and QStandardItem

Hello!

I have a question which concerns models and items in models and probably a bit QVariant. The question is: why will not appear a picture after executing the code presented bellow?

Qt Code:

Switch view

QStandardItem *item2 = new QStandardItem;
    QVariant v1;
    QIcon ico(":/block.png");
    v1.setValue(ico);
    item2->setData(v1, Qt::DisplayRole);
    model->setItem(0, 0, item2);
    QTreeView *tv = new QTreeView;
    tv->setModel(model);
    tv->show();

QStandardItem *item2 = new QStandardItem;
    QVariant v1;
    QIcon ico(":/block.png");
    v1.setValue(ico);
    item2->setData(v1, Qt::DisplayRole);
    model->setItem(0, 0, item2);
    QTreeView *tv = new QTreeView;
    tv->setModel(model);
    tv->show();

To copy to clipboard, switch view to plain text mode

And another question, which was born by my curiosity, is: Does QStandardItem class's method setData work only with primitive data, such strings, integers etc.? Does it depend on QVariant-class?
