QStandardItemModel :: removeRows（）是否递归？

Question

在具有树结构的QStandardItemModel上调用removeRows() ，是否递归为所有子级QStandartItem释放了内存？

Answer 1

Is QStandardItemModel::removeRows() recursive?

No. It can't be since a model isn't a tree of models.

does this free the memory for all the children QStandartItem s recursively?

Yes, but this has little to do with removeRows() . The ~QStandardItem() destructor disposes of the children. So any method that destroys a QStandardItem will also destroy and dispose of the children. Nothing will leak.
