I second the answer above: ProxyWidget is the answer.

Here is my working code, Header:

class CenterScreen{
private:
    QListWidget* nameListWidget;
    QGraphicsProxyWidget* nameProxyWidget;
...

C++ source:

void CenterScreen::addListView()
{
    QGraphicsScene* scene = ui.centerGraphicsView->scene();
    nameListWidget = new QListWidget();
    nameProxyWidget = scene->addWidget(nameListWidget);
...
    nameProxyWidget->hide();    // you can control your widget as you like

What about QGraphicsProxyWidget?

QListView *listView = new QListView;
QGraphicsProxyWidget *proxy = scene.addWidget(listView);

Then (or before that) you can populate the list with anything you want. QPushButton can be added to the list using setIndexWidget(). Also you might rethink the whole idea of having a QListView, and give it a try with QScrollArea and a linear layout containing buttons. That would require a bit more logic to organize items within the scroll area, but it should be more lightweight that QListView with custom widgets.
