QAbstractItemModel: How to signal major change?

[nonot1]

Hello,

If I've got a QAbstractItemModel based hierarchal model, and I need to make significant changes to it's structure at run time, what functions do I need to call to alert the view before and after the change?

(Rows would need to be added, removed, and relocated at the same time. Columns would not change.)

Since, I don't see any generic beginModelReorganization() and endModelReorganization() calls, what is the correct procedure?

Is it just beginResetModel()/endResetModel() to completely clear any viewer state?

Thank you

You should call "QAbstractItemModel::beginResetModel() ":http://doc.qt.nokia.com/4.7/qabstractitemmodel.html#beginResetModel and "QAbstractItemModel::endResetModel() ":http://doc.qt.nokia.com/4.7/qabstractitemmodel.html#endResetModel
