How to access to the model from an editor? was created by
Hi,
i want to make a custom editor for a combobox. For the items of the combobox i want to get form the data method of the model (Qt::UserRole) as a QStringList. Over the GridEditorSite i can get the ModelIndex, but how i can get the pointer to the model? Or do you have a better idea to fill the list of the combobox without using a relation model?

QModelIndex has link to the model that hold it.
const QAbstractItemModel * QModelIndex::model() const.

Other way you can get the model reference from dataBinding:
site->dataBinding()->controller()->model().

Additionaly the dataBinding() has the method to get relation model:
site->dataBinding()->relationModel().

Can i use the relation model with a QStringListModel? How can i set the foreign key with this model?

I think not. This model contains only one column. No place to put the foreign key in it.
I'd suggest QStandardItemModel instead of QStringListModel.
