    Okay, tried it with emit dataChanged(invisibleRootItem()->index(), rootEntry->index(), vector); which should work, but it doesn't.

      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.
