How to exclude dirs in QFileSystemModel?

Question

I use this code.

 QFileSystemModel* fsModel = new QFileSystemModel(this);
 fsModel->setFilter(QDir::NoDotAndDotDot | QDir::Dirs );

I can not understand how to exclude some folders.

Answer 1

Subclassing from a standard model is of course possible, but is considered bad style. You'll gain a nice reusable component by implementing a generic filter proxy model. Inherit from QAbstractProxyModel and implement a filter proxy.
