My Google skills must be failing me today.

I've inherited from QTreeView to create a TreeView that stores a QStandardItemModel instead of a QAbstractItemModel. I have also inherited from QStandardItem to create a class to store my data in an item as is necessary.

I've successfully inserted my derived QStandardItem into my derived QTreeView's QStandardItemModel. Now the trouble is, I can't figure out how to style it. I know that QTreeView has a setStyleSheet(QString) member, but I can't seem to get it working. It may be as simple as I'm not styling the correct attribute. Any pointers would be appreciated. Thanks.

For clarity, here are my class defs.

class SurveyTreeItem : public QStandardItem
{
public:
    SurveyTreeItem();
    SurveyTreeItem( const QString & text );
    ~SurveyTreeItem();
};

class StandardItemModelTreeView : public QTreeView
{
    public:

    StandardItemModelTreeView(QWidget* parent = 0);
    ~StandardItemModelTreeView();

    QStandardItemModel* getStandardItemModel();
};

I've tried the following StyleSheets:

StandardTreeView::Item
{
font: 87 12pt 'Arial Black';
}

StandardTreeView::QStandardItem
{
font: 87 12pt 'Arial Black';
}

QTreeView::QStandardItem
{
font: 87 12pt 'Arial Black';
}

QTreeView::Item
{
font: 87 12pt 'Arial Black';
}

QTreeView::SurveyTreeItem
{
font: 87 12pt 'Arial Black';
}

StandardTreeView::SurveyTreeItem
{
font: 87 12pt 'Arial Black';
}
