如何以编程方式移动到Qt中的选定行

Question

我使用QTreeView和QSortFilterProxyModel

// Here I determine the index, that was saved before (_lastAddObjectIndex - QModelIndex)
QModelIndex next_index = _proxyModel->index(_lastAddObjectIndex.row(), 0);

// Here I select the row programmatically, and after that I'd like to move to that row (because table might have many rows)
view->selectionModel()->select(next_index, QItemSelectionModel::ClearAndSelect | QItemSelectionModel::Rows | QItemSelectionModel::SelectCurrent);

Answer 1

我认为移动意味着滚动。如果是这样，您可以通过使用以下API：来实现这一点

view->scrollTo(next_index);

如果将第二个参数传递给该方法，您甚至可以更改滚动提示。这取决于您是否对默认值满意，默认值只是确保项目可见。

您可以参考文档来进一步微调这种行为，以备不时之需。
