Help on gtkmm eeview drag and drop

[Chun Yang <achunyang2010 gmail com>]

Hi All,

I am working on a project that has a treeview of items. The tree items can be draged and dropped from one place to another. I got the tree view work by following the examples.

Now I got one question:
In the process of drag&drop, I also want to operate on data structure represented by the tree view. For example when one item is dragged and dropped to another item, I want to remove the link to it from its old place and add the link to its dropped place in a data structure behind the treeview. How do I do this? What is the function to use? If you could point me to some example that would be great.

Thank you very much!
