Answer 1

You should implement and set your own proxy model:

void QFileDialog:: setProxyModel (QAbstractProxyModel * proxyModel)

Sets the model for the views to the given proxyModel. This is useful if you want to modify the underlying model; for example, to add columns, filter data or add drives.
