Simple way to expand all nodes on a QTreeView?

[jpn]

This might not be the most efficient way..

QModelIndexList indexes = model->match(model->index(0,0), Qt::DisplayRole, "*", -1, Qt::MatchWildcard|Qt::MatchRecursive);
foreach (QModelIndex index, indexes)
	tree->expand(index);

QModelIndexList indexes = model->match(model->index(0,0), Qt::DisplayRole, "*", -1, Qt::MatchWildcard|Qt::MatchRecursive);
foreach (QModelIndex index, indexes)
	tree->expand(index);
