この QAbstractItemModel と QSortFilterProxyModel の相互作用の何が問題になっていますか? 画面の左側で QAbstractItemModel の実装を接続し、右側で QSortFilterProxyModel を実行しました。
UPD:コードをアップロードします: git@bitbucket.org:h0x0d9/myfilterproxymodel.git
コード:
ListsRegisterModel *model = new ListsRegisterModel(this);
QSortFilterProxyModel *proxyModel = new QSortFilterProxyModel(this);
proxyModel->setSourceModel(model);
QTreeView *view = new QTreeView(this);
view->setModel(model);
QTreeView *view2 = new QTreeView(this);
view2->setModel(proxyModel);
