    Or at least I think that should update everything from the root item to the newly created entry.

      How are you adding that new row outside the constructor ?

        With the appendRow() method (on the invisible root item) as mentioned earlier.

          I meant, where are you calling appendRow ?

            In a function that is called in response to a button click. (that function calls addRootItem multiple times)

              What about using beginInsertRows() / endInsertRow() ?

                That doesn't seem to work either.

                  Does anyone know of some piece of sample code for a dynamic model with Qt Quick and QStandardItemModel where you can add rows and edit items after the construction?

                    Oh, Damnit. I had a ProjectTreeViewModel { id:projecttreeviewmodel } in my UI components and used that instead of my treeviewmodel added as a context property.
