Expecting your answers..
I think you would have to keep track of how many rows you hide, or perhaps traverse the entire tree and look for non-hidden rows, which would be expensive. Alternatively, you could try to create a proxy model, based on QAbstractProxyModel, but that might turn out to be a challenge in itself.
