How to Customize the treeView?

[stereomatching]

I want to make the QTreeView show the data without files
So I inherit QTreeView and override "isIndexHidden"
But the customTreeView still show the files

[code]
class customTreeView : public QTreeView
{
protected:
bool isIndexHidden( const QModelIndex &index ) const
{
QDirModel dirModel = static_cast<QDirModel>(model());
qDebug() << dirModel->fileName(index);
if(dirModel->fileInfo(index).isFile())
return true;

    return false;
}

};

inline int customTableViewTest(QApplication &app)
{
QDirModel model;

QTreeView view;
view.setModel(&model);

customTreeView cView;
cView.setModel(&model);

QSplitter splitter;
splitter.addWidget(&view);
splitter.addWidget(&cView);
splitter.show();    

return app.exec();

}
[/code]

How could I fix it?Thanks
