The the node to be modified is identified by

"WModelIndex selected = *treeView_->selectedIndexes().begin()"

where treeView_ is a WTreeView.

If I cannot change it, how can I remove it?

Hey Fransesco,

Given the index, you modify the underlying model at that index, and this will be automatically reflected in the view.

All changes should be made on the model.

You can use the WAbstractItemModel API to make the changes (which has as benefit that it will work with any concrete model implementation), or you can use the API of the specific model you are using, e.g. WStandardItemModel API, which is more convenient.

Regards,

koen

Hey Fransesco,

To remove a node with given index:

model->removeRow(index.row(), index.parent());
