[Marble-devel] Adding placemarks using Marble bindings for Python

[Dennis Nienhüser]

Hi,

your approach looks right to me. The Python bindings indeed lack the
treeModel (and some other) methods. I created bug 322573 [0] to track it
down. Hopefully we can extend them to cover more of our API.

Regards,
Dennis
