I use this code.

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

I can not understand how to exclude some folders.

有帮助吗?

解决方案

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.

其他提示

Create a filter model and use your QFileSystemModel as its source.

For your filter, QSortFilterProxyModel has most of what you need - you'll only have to provide a reimplementation of filterAcceptsRow to make the decision of which files should be passed through.
