disconnect ( )

[26]

A helper class for iterating over a model that might change.

[27]

When populating the ListView from a model under normal circumstances, we would iterate over the range of model indices correspondning to the visual range, and basically call createItem(index++) in order to create each item.

This will also emit Component.onCompleted() for each item, which might do some weird things... For instance, it might remove itself from the model, and this might change model count and the indices of the other subsequent entries in the model.

This class takes such changes to the model into consideration while iterating, and will adjust the iterator index and keep track of whether the iterator has reached the end of the range.

It keeps track of changes to the model by connecting to QQmlInstanceModel::modelUpdated() from its constructor. When destroyed, it will automatically disconnect. You can explicitly disconnect earlier by calling
