Clearing *all* rows in QAbstractItemModel (tree)
Message 1 in thread
I've derived from QAbstractItemModel to implement my own "tree"
model (e.g., a file system tree).
I now want to clear *all* the nodes, and re-populate it.
Must I recursively iterate each node and call
beginRemoveRows(parent,first,last);
// ...do it
endRemoveRows();
Or, is there a simpler way to permit me to clear all (row) state
in the model?

It should be sufficient to do this only on the top-level-items.
