How to reparent using tree.hh

Question

Here I have a window with a list of groups of rows. In the image above, Path 2 to 6 are children of Group1.

The container used for this tree is tree.hh. What function would I use to make Group1 (and its children) be child of Path 10. I don't want to delete rows and put them back again, just re-parent. Thanks!

I guess you should look at ::move_after()
